4.) Multiple alleles control the intensity of pigment in rabbits. The gene R1 is full colour, R2 is dilute colour and R3 is deadly when homozygous. R1 is dominant to R2 which is dominant to R3. When a full colour male is mated to a dilute colour female, the offspring ration is 2 full colour to one dilute to one dead. What are the genotypes of the parents?

Step 1
However, we don't know the second allele yet. It could be R1, R2, or R3. Second, we know that the dilute color female must have the genotype R2R2. This is because R2 is recessive to R1, so the female cannot have an R1 allele or she would be full color. And she Show more…

Four alleles control fur color in rabbits. C is brown, cch is chinchilla, ch is Himalayan, and cc is albino. These alleles form this allelic series: C > cch = ch > cc You cross a Ccch X chc If they produce 100 offspring together in their lifetimes, how many would you expect to exhibit the albino phenotype?

In rabbits, an allelic series helps to determine coat color: $C$ (full color), $c^{\mathrm{ch}}$ (chinchilla, gray color), $c^{\mathrm{h}}$ (Himalayan, white with black extremities), and $c$ (albino, all-white). The $C$ allele is dominant over all others, $c^{\text {ch }}$ is dominant over $c^{\text {h }}$ and $c, c^{\text {h }}$ is dominant over $c$, and $c$ is recessive to all the other alleles. This dominance hierarchy can be summarized as $C>c^{\mathrm{ch}}>c^{\mathrm{h}}>c .$ The rabbits in the following list are crossed and produce the progeny shown. Give the genotypes of the parents for each cross: (FIGURE CANNOT COPY)
