dominant traits show up in the first generation so any disorders have a 50% percent chance of showing up in offspring. recessive traits skip a generation therefore any diseases would have on a 25% chance.
Not necessarily. I think the dominant genes are more common, but there are lot of exceptions out there. For example, having six fingers in humans is a dominant gene, but it isn't all that common.
If the recessive genotype is selected for more often than the dominant genotype, the recessive allele will become more common than the dominant allele in the gene pool.
Dominant traits are expressed over recessive traits because the dominant allele codes for a functional protein that masks the effects of the recessive allele. In a heterozygous individual carrying one dominant and one recessive allele, the dominant allele is expressed, leading to the dominant trait being observed.
They're not necessarily, but they can be. When a recessive trait is more common, it likely because it was advantageous to have that trait so the species evolved to have more of it in the gene pool. Also, since dominant traits are expressed over recessive traits, natural selection has more of an effect on them.
dominant-appears in first generation recessive-seems to dissapear

Dominant allele because its more likely to be received by the next generation.
yes,of course
There are no such things as dominant and recessive genes. There are only dominant and recessive alleles. Dominant alleles are parts of a gene that present its features over the recessive allele, which is the one that is always masked by the dominant allele. The recessive allele's trait only shows if both of the alleles in a trait are recessive.

There would likely be more children with the dominant phenotype because it only requires one copy of the dominant allele to express the dominant trait, whereas the recessive phenotype requires two copies of the recessive allele.
A recessive trait is a trait that is not shown or expressed physically but is retained within the persons genes, whereas a dominant trait is a trait which opresses the recessive trait and is prodominantly shown or expressed physically. For example it is possible for two red-haired parents, both with recessive dark haired genes, to have a dark haired child. they must both have the recessive gene or the dominant gene of red - hair will be expressed in the child
Dominant trait is the one which is expressed when the homologous pair of genes controlling it are either homozygous or Hetrozygous dominant; on the other hand recessive trait has both genes to be homozygous recessive. in fact trait is controlled by the form of genes. Dominant gene expresses even when it is in the company of recessive gene. However recessive gene expresses only when in company of recessive gene
Recessive genes do not become dominant. Dominant genes mask the expression of recessive genes in the presence of both alleles. However, if a recessive gene is selected for over time through breeding, it can become more prevalent in a population.
Characteristics that are more common than others are dominant. Recessive traits are not expressed when paired with a dominant trait.
