In garden peas, height is determined by a single gene with tall being dominant to short. In his original experiment Mendel crossed a pure tall plant with a pure short plant. Show this cross!
What is (see board).
400
This chart is used to find all possible allele combinations in a cross.
What is a Punnett Square.
500
In guinea pigs, long hair (H) is dominant to short hair (h). A guinea pig is homozygous recessive. What is its genotype?
What is hh.
500
True or false: organisms can acquire new traits over the course of a lifetime.
What is false!
500
In garden peas, height is determined by a single gene with tall being dominant to short. If two heterozygous plants are crossed, what is the probability of having tall offspring will be homozygous dominant? Use a Punnett square to show your work.
What is 25% (see board for punnett square).
500
If two parents are carriers of a recessive genetic disorder (like cystic fibrosis), is it possible for their child to get the disease? Why?
What is yes, the parents could each pass on the recessive allele giving the child a homozygous recessive genotype and therefore the disease.
