OK, we know that these genes are linked and we know the genotypes of the male's and female's parents. The male's parents' genotypes are DDll and ddLL. The female's parents had genotypes of DDLL and ddll. The male and female each received one chromosome from each parent. Knowing this, which of the images below represent the male's pair of homologous chromosomes and which the female's?

Now return to the question page and select the correct answers.

Now that you know which genes are linked in the male, what gametes will he produce?

Crossing over occurred in the female so what gametes will she produce now?

Now that you know what gametes the male and female will produce, perform a punnett square to determine what the offspring will be.

Your punnett square should look similar to the one below. If it does not, review the material on gamete formation and how to set up the punnett square and try again.

	DL	Dl	dL	dl
Dl	DDLl	DDll	DdLl	Ddll
dL	DdLL	DdLl	ddLL	ddLl

Count up how many of the offspring have each of the genotypes and phenotypes.

Now return to the question page and select the correct answers.
