autosomal recessive, autosomal dominant, x-linked recessive, or x-linked dominant
I-1, I-2, II-4, II-5, III-1
A white rabbit is crossed with a brown rabbit, half of the resulting progeny are brown and half are white. When the brown brown rabbits from this cross are interbred, all of the offspring they produce are brown. On the basis of these results, what can you conclude?
One of the parental rabbits is heterozygous while the other is homozygous recessive.
Because of the inferred genotypes for the for the parental generations we can say the parental cross was a testcross.
Because of the interbreeding of the brown rabbits produced only brown offspring, this indicates their genotype is homozygous recessive.
