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?
Stabilizing selection would result in a graph showing a peak at the intermediate phenotype, with fewer individuals at the extreme phenotypes. This is because individuals with intermediate phenotypes are favored, leading to the reduction of extreme phenotypes in the population over time.
Is Rett syndrome dominant or recessive?
Rett syndrome is a rare genetic disorder that is typically caused by a mutation in the MECP2 gene located on the X chromosome. It is not classified as dominant or recessive in the traditional sense because it primarily affects individuals with two X chromosomes. It is considered an X-linked dominant disorder with variable expressivity and reduced penetrance.
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 does the environment affect phenotypes?
The nervous system

Describe how phenotypes can be used to predict genotypes in a pedigree?
By observing the phenotypes of individuals in a pedigree (such as their physical characteristics or traits), one can infer the genotypes that may be responsible for those traits. By looking at patterns of inheritance within the pedigree, such as autosomal dominant, autosomal recessive, or X-linked inheritance, one can make educated guesses about the genotypes of individuals based on their observed phenotypes. However, the presence of genetic variability, incomplete penetrance, or phenocopies can complicate the prediction of genotypes solely based on phenotypic information.

What are ict gadgets?
nd support ICT proper functioning and expressivity. - Iginla S.L. (MEGATREE CONCEPT)
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.
Distinguish between parental and recombinant phenotypes?
Parental phenotypes are the phenotypes that are seen in the offspring that are the same as the phenotypes of the parents. Recombinant phenotypes are the phenotypes that are the result of recombination events during genetic crossing, resulting in combinations of traits not present in the parents.
When two extreme phenotypes are selected in natural selection the intermediate phenotypes become?
The intermediate phenotypes tend to be selected against, resulting in stabilizing selection that favors the extreme phenotypes. This can lead to a reduction in genetic variation within the population, as individuals with intermediate traits are less likely to survive and reproduce.
Can phenotypes OB produce genotypes As?
No.
