The process by which genotype becomes expressed as phenotype is called recombination. Recombination usually occurs naturally and during meiosis.

In a population of horses an extreme phenotype is favored and the distribution of genes in that population shifts toward that phenotype This process is called selection?
the process is called an DIRECTIONAL selection.
What process does differential selection and reproduction of phenotype occurs?
cellular differentiation
Crossing over causes the offsprings to be different from the parent?
Chromosomal cross-over is what causes the offspring to be different from the parent. The chromosomal cross-over process occurs during meiosis I.
What advantage does the process of crossing over bring to the reproductive process?
It produces offspring with genetic variation, different from the parent gametes. This is opposed to asexual reproduction where identical offspring are the product. This is the diversity that is created on the levels of genotype and phenotype.
When an ADP molecule gains a phosphate it becomes an ATP molecule. This process is called .?
phosphorilation
Is recessive the process in which DNA changes to form new alleles?
No, recessive traits refer to the inheritance pattern of the allele. In the simple case where a trait is either expressed or not, if it is a recessive trait it will only be the expressed phenotype when it is homozygous. Dominant allele phenotypes will show if the genotype is heterozygous.

What are phenotypes and their difference to genotypes?
A phenotype (from Greek phainein, 'to show' + typos, 'type') is the composite of an organism's observable characteristics or traits: such as its morphology, development, biochemical or physiological properties, phenology, behavior, and products of behavior (such as a bird's nest). Phenotypes result from the expression of an organism's genes as well as the influence of environmental factors and the interactions between the two. Genotype vs Phenotype Genotype and phenotype are terms used to differentiate between the genetic makeup of an organism and the way it expresses itself. A genotype refers to the actual set of genes that an organism carries inside. When these genes are expressed under observable conditions, they are called phenotypes and the expressions are called phenotypic expressions. Wondering how they are different? After all, how can a man be different from the genes he has inherited? The fact is, phenotypes are dependent on the genes they inherit. However, their expression is also influenced by environmental factors. The influence of the environment modifies the role that the genes play to a certain extent. The expression of the genes, modified by environmental factors, produces a phenotype. A genotype basically determines the type of traits that a phenotype can have. For instance, the genotypic traits of an organism will determine his susceptibility to a certain disease. However, the phenotypical aspect of the organism displays observable aspects of this disease. The symptoms related to the particular aspect of the disease, the presence or even the absence of such a disease are phenotypic expression. Let us take up another example. It is the genotypic variation between XX or XY chromosomes that create the difference between the two sexes. Once again, the differences that you see before you are phenotypic, but the reason behind them is genotypic! Finally, every organism is a single genotype class. The only exceptions are identical twins. Even in these twins, there may be different phenotypes, though they belong to the same genotype! In practical terms, the two terms are not used in an absolute manner. Their descriptions are used in a partial manner to explain certain characteristics in organisms. Summary: 1. Genotype decides the genetics and inherited traits of an organism, but phenotypes refer to the actual display of these traits 2. Genotypes are decided by inherited genes, while phenotype are determined by the effect of environmental factors 3. The genotype largely determines the ultimate phenotype of an organism. 4. The more complex a biological process, the more is the effect of environmental factors on it and therefore the chances of a predominant phenotype. Source : Internet
What is the difference between phenotypes and genotypes?
Genotype are the unseen differences in genetic combinations of an individual. Phenotypes are the expressed and seen differences of an individual.A genotype is the genetic makeup of an organism with reference to a single trait, set of traits, or an entire complex of trait; that is, genotype is the type of genes you have. A phenotype is the physical characteristic of an organism. So the genotype decides the genetics and inherited traits of an organism, but phenotypes refer to the actual display of these traits. Genotypes are decided by inherited genes, while phenotypes are determined by the effect of environmental factors as well. The more complex a biological process, the more is the effect of environmental factors on it and therefore the chances of a predominant phenotype.For example, say recessive allele t codes for albinism (a congenital disorder) and dominant allele T is normal. Two individuals have different genotypes: TT and Tt. Because they both have an allele T, neither have albinism; therefore, they have different genotypes but the same phenotype. An individual with a genotype tt would have albinism and would therefore have a different phenotype than the previous two.Another example: Identical twins have the same genes and the same genotype. Every now and then a gene in one of the twins will be expressed differently from the gene in the other twin. They will have different phenotypes. So phenotype is a fancy word used when a gene works one way under certain conditions and a different way under other conditions.An easy way to remember that (from what I've learned from my science teacher) is to think "Pheno" as "Photo", like if you take a picture, you'll only be able to see the outside of somebody; what they look like..In more detail:Take alleles R and r. If R and R display a "complete dominance" relationship, then RR , Rr, and rr are different genotypes, but two are the same phenotype. RR and Rr display the same trait because R is completelycovering up r's trait, but rr will show the recessive trait.EX: A flower with R as a red trait and r as a white trait has the following phenotypes for each genotype:RR: redRr: redrr: whiteAdditional information:If R and r display a "codominance" relationship, then RR, Rr, and rr are different genotypes and phenotypes. RR shows the dominant trait, while rr shows the recessive trait. Rr shows a combination of the two, as if the two were dominating cooperatively.EX: A flower with R as a red trait and r as a white trait has the following phenotypes for each genotype:RR: redRr: red and whiterr: whiteIf R and r display a "incomplete dominance" or "incomplete inheritance" relationship, then RR, Rr, and rr are different genotypes and phenotypes. RR shows the dominant trait, while rr shows the recessive trait. Rr shows when R incompletely dominates r, allowing some of its qualities show. EX: A flower with R as a red trait and r as a white trait has the following phenotypes for each genotype:RR: redRr: pinkrr: white

How do cells work inside a body?
Cells are actually the elemental constituents of body who unite together to form tissues and these later unite to form an organ, then organism. So it can be said that cells are building blocks of human body. The cells can be haploids or diploids and they form chromosomes. the Chromosomes can be either sex linked chromosomes or non sex linked chromosomes. These cells undergo cell division process either through "MITOSIS" or "MEIOSIS" to form chromosomes. Depending upon there linkage as sex or non-sex they help in determining the genotype and phenotype of the organism. Thus we see that it's the cells that determine the genotype or the genetic constituent of the organism and also the phenotype or the physical characteristics of the organism.
