Refer to the crosses that you worked out on the front of this page to answer questions 1-8
1.
What crosses will result in all dominant phenotype offspring?
2.
What cross will result in all recessive phenotype offspring?
3.
What cross will result in half dominant and half recessive phenotype offspring?
4.
What cross will result in a ratio of 3 dominant phenotype offspring for every 1 recessive offspring?
5.
What cross will result in a 1:2:1 genotype ratio in the offspring?
6.
What cross will result in all homozygous recessive offspring?
7.
What cross will result in half homozygous dominant offspring and half heterozygous offspring?
8.
What cross will result in all heterozygous offspring?
In dogs, black fur (B) is dominant over yellow fur (b). A homozygous black dog is mated with a yellow dog.
Do a punnett square to show the cross and predict the offspring (phenotypes and genotypes)
9.
In dogs, black fur (B) is dominant over yellow fur (b). A heterozygous black dog is mated with a yellow dog.
