A phenotype trait that is depending on several genes is said to be:

Cystic fibrosis (CF) is an autosomal recessive trait. A three-generation pedigree is shown below for a family that carries the mutant allele for cystic fibrosis. Note that carriers are not colored in to allow you to figure out their genotypes.      Normal allele =  F      CF mutant allele =  f        What is the genotype of individual #13? A) ff B) FF C) Ff  D) it is impossible to tell

A set of true breeding white cows were crossed with true breeding black cows to produce all brown colored offspring. If the F2 generation yielded 113 brown, 47 black and 50 white what type of inheritance would that reflect? Full credit will only be awarded when you show your work and explain your reasoning. The type of inheritance reflected is Codominant since 50% of the offsprings doesn’t reflect the color of either parent. A single new phenotype is presented when one allele of dominance and one allele for recessive trait is paired heterozygous. This shows that for a specified gene, there are three possible phenotypes that can arise from pairing, a phenotype for homozygous dominant, homozygous recessive. For heterozygous, the allele that is dominant, W, is codominant to the allele that is recessive, w, and when paired together neither is expressed but a blended, or mixed phenotype is expressed.

The gene for flower position in pea plants exists as axial or terminal alleles. Given that axial is dominant to terminal, list all of the possible F1 and F2 genotypes and phenotypes from a cross involving parents that are homozygous for each trait. Express genotypes with conventional genetic abbreviations.
