Question 1

(True False)

Free
Mendel's law of independent assortment suggests that the inheritance of one gene or trait does not influence the inheritance of a separate unlinked trait.

Question 2

(Multiple Choice)

This question is about Mendel's pea experiments. What genotype and phenotype proportions are expected from a cross between two plants that are heterozygous for pea color and shape? The parent plants have round, yellow peas. Please select all that apply.

A) 1/16 YY RR
B) 4/16 yy rr
C) 3/4 yellow peas
D) 1/4 wrinkled peas
E) 1/2 Yy Rr

Answer

Question 3

(Short Answer)

Free
When considering the inheritance of multiple independent traits, it is often simpler to multiply the probability of each individual trait to determine the probability of the overall phenotype. Assuming inheritance is independent, in a cross between two tall pea plants with yellow round peas and purple flowers, genotype YyRrTtPp, what is the probability that offspring will be tall and have white flowers and produce yellow wrinkled peas? Your answer should be the value of A in the fraction A/256
