Answer and Explanation:
- The phenotype of the heterozygous plant is
green pods
- The genotype of the heterozygous plant is Aa
- The genotype of the plant with yellow pods is aa
- The genotype of the gametes produced by the heterozygous plant is 50% A 50% a
- The genotype of the gametes produced by the plant with yellow pods is 100% a
- The expected frequency of F_1 plants with yellow pods is 50%
- The expected frequency of F_1 plants with the genotype AA is 0%
Cross) a heterozygous plant is crossed with a plant that has yellow pods
Parental) Aa x aa
Phenotype) Green pods Yellow pods
Gametes) A a a a
50% 50% 100%
Punnet Square) A a
a Aa aa
a Aa aa
F1) 2/4 = 1/2 = 50% Aa, Plant with Green pods
2/4 = 1/2 = 50% aa, Plant with Yellow pods
Amylase is the starch digesting enzyme. This enzyme is found in both saliva (to break down starch in our mouth) and also in out small intestine after it's released from the pancreas.
Hope this helped.
males only have one x chromosome (d)
in sex linked traits males always express it as they have x y chromosomes and can't cover up the trait whereas females have two x chromosomes and can cover up the trait
