When a trait has more than two different forms it would be best described by what terms. A. Recessive B. Dominant C. Incomplete dominance D. Phenotypic E. Multiple alleles?
E. Multiple alleles. Multiple alleles refers to a gene that has more than two alleles which can result in a larger number of possible trait variations. This is different from traits that are controlled by dominant and recessive alleles, or exhibit incomplete dominance.
What are the genotypic andphenotypic expectancies for a cross between a heterozygous and homozygous individual?
In this case, the genotypic expectancy would be 50% heterozygous and 50% homozygous offspring. The phenotypic expectancy would depend on the specific traits being studied and whether they exhibit dominance or recessiveness. If the trait is dominant, the phenotypic ratio would likely be 100% expressing the dominant trait.
What does an alleles for a hybrid tall pea represent?
An allele for tall in a hybrid pea plant represents the gene that codes for the trait of tall height. In the case of a hybrid plant, there are two alleles for height, one inherited from each parent. If both alleles are for tall height (TT or Tt), the plant will exhibit the tall trait.
What is the phenotypic ratio for a F1 cross?
The phenotypic ratio for a monohybrid cross in the F1 generation is typically 3:1. This means that three-quarters of the offspring will exhibit one phenotype, while one-quarter will exhibit a different phenotype. This ratio is based on Mendelian inheritance patterns.
What do genes that have more than two possible alleles have?
Genes with more than two possible alleles exhibit multiple variations of a particular trait or characteristic. This increased genetic diversity can lead to a wider range of phenotypic expressions within a population. An example of this is blood type, which can have multiple alleles (A, B, O) resulting in different blood types.

Which phenomenon is demonstrated by light but not by sound waves?
Interference is a phenomenon demonstrated by light but not by sound waves. Interference occurs when two or more waves overlap in space and combine to produce a resultant wave. Light waves can exhibit interference patterns such as in Young's double-slit experiment, while sound waves do not exhibit similar interference effects.
Why are many harmful alleles recessive?
Many harmful alleles are recessive because they usually interfere with normal biological processes or functions. To exhibit their harmful effects, both copies of the recessive allele need to be present in an individual, leading to a higher threshold for expression. In contrast, dominant alleles only need one copy to be expressed, making harmful effects more immediate and noticeable.
What is the phenotypic ratio of the following dihybrid cross AaBb x AaBb?
The phenotypic ratio of the cross AaBb x AaBb is 9:3:3:1, which represents the different possible combinations of genotypes for the offspring based on the principles of Mendelian genetics. This ratio indicates that 9 out of 16 offspring will exhibit the dominant phenotype for both traits, while 3 out of 16 will exhibit one dominant and one recessive phenotype, 3 out of 16 will exhibit the other dominant and recessive phenotype, and 1 out of 16 will exhibit both recessive phenotypes.
Some alleles are neither dominant or recessive and many traits are controlled by what?
Each person has two alleles of one particular gene, which controls one particular characteristic, such as a person's blood group. An allele may be either dominant, recessive, or codominant. A dominant allele would dominate the other allele in the chromosomes, meaning only the dominant allele would contribute to an organism's characteristics. An example of this is the A blood group, which is dominant to the O allele. However, if an individual has both A and B alleles, A and B are codominant, as they both exhibit effects on an organism's characteristics (the blood group). This results in an AB blood group - a combination of the effects of two genes!
Can antibiotics exhibit side effects four days after completing the course?
Unfortunately antibiotics can and do exhibit side effects four days after completing the course. I never start antibiotics without taking acidophilus and eating lots of yogurt.
What is the phenotypic ratio for a F1 cross?
The phenotypic ratio for a monohybrid cross in the F1 generation is typically 3:1. This means that three-quarters of the offspring will exhibit one phenotype, while one-quarter will exhibit a different phenotype. This ratio is based on Mendelian inheritance patterns.
How are the symbols written for alleles that share incomplete dominance?
For alleles that exhibit incomplete dominance, a capitalized letter is used to represent the dominant allele, and a lowercase letter of the same symbol represents the recessive allele. When writing these alleles, you can denote the incomplete dominance by writing superscripts (e.g., A^1, A^2).
Does the story his grandfather's old ram exhibit certain effects of a bad memory?
yes
What type of graph would represents a polygenic trait?
A histogram or a bell curve would be suitable for representing a polygenic trait, as these traits are influenced by multiple genes and exhibit a continuous range of phenotypic values in a population.
Does matter dual nature?
Yes. Sub-atomic particles exhibit both particle effects (no surprise) but also wave effects. This has been known since about 1927.
What is a hybrid genotype?
Mm, Ff, Gg, Ll, Ss and ect
