What factor besides alleles affect phenotypes?
Enviroment, development, and behavior are all factors besides alleles that can affect phenotypes.
Explain how stabilizing selection would affect a graph of the distribution of phenotypes for a trait?
I would make the graph narrower.
How many phenotypes does the trait have?
Aa AA aa If A dominant, two phenotypes.
Which occurrence is when an individual inherits a dominant gene but does not fully express the dominant phenotype?
Incomplete penetrance
How are phenotypes and genotypes related to natural selection?
Natural selection favours phenotypes that bestow a reproductive advantage, thereby increasing the frequency of alleles (genotype) producing those phenotypes.
How does the environment affect phenotypes?
The nervous system

What are ict gadgets?
nd support ICT proper functioning and expressivity. - Iginla S.L. (MEGATREE CONCEPT)
Which can you physically see genotypes or phenotypes?
You can see the phenotype. A good way to remember is that a photograph is what you see. The genotype is the graphic representation of the trait.
Which occurrence is when an individual inherits a dominant gene but does not fully express the dominant phenotype?
Incomplete penetrance
What is incomplete penetrance?
Referring to the presence of a gene that is not phenotypically expressed in all members of a family with the gene.
How are phenotypes and genotypes related to natural selection?
Natural selection favours phenotypes that bestow a reproductive advantage, thereby increasing the frequency of alleles (genotype) producing those phenotypes.
When two extreme phenotypes are selected in natural selection the intermediate phenotypes become?
Highly reduced, or, nonexistent.
Describe how phenotypes can be used to predict genotypes in a pedigree?
When enough phenotypes in a family are known the genotypes can be infered.
Define and distinguish between pleiotropy and polygenic inheritance?
Pleiotropy: one gene affects many traits (phenotypes) Polygenic: many genes affect one trait (phenotype)
