Question

Short hair in rabbits is governed by a dominant allele, L, and long hair by its recessive allele,

1. Black hair results from the action of the dominant genotype BB or Bb, and brown hair from the recessive genotype bb. The two loci are independent of each other. Provide the expected genotypic percentages of offspring produ from a cross between and Libb animals: (Indicate the response as a whole number rounded to one decimal place [i.e., 13.5).)
1) Fill-in-the-Blank From the mating, the percentage of offspring expected to be LLBb: % (percent)
2) Fill-in-the-Blank From the mating, the percentage of offspring expected to be LLob: % (percent)
3) Fill-in-the-Blank From the mating, the percentage of offspring expected to be LIBb: % (percent)
4) Fill-in-the-Blank From the mating, the percentage of offspring expected to be Libb: % (percent) % (percent)
5) Fill-in-the-Blank From the mating, the percentage of offspring expected to be 11Bb:
6) Fill-in-the-Blank From the mating, the percentage of offspring expected to be libb: % (percent)
7) Multiple Choice/Select One Indicate the possible gametes from a doe with the genotype.

Answer 1

The expected genotypic percentages of offspring produced from a cross between Libb animals are 50% LLBb and 50% Libb. The genotype LLob, LIBb, 11Bb, and libb are not possible based on the given information. The possible gametes from a doe with the genotype Libb are LB and Lb.

Step-by-step explanation:

The cross between two rabbits with genotypes Libb is used to determine the genotypic percentages of their offspring.

1. From the cross, the percentage of offspring expected to be LLBb is 50%.
2. The percentage of offspring expected to be LLob is 0% since the long hair is a recessive trait and is represented by the genotype 1.
3. The percentage of offspring expected to be LIBb is 0% since the genotype Libb is not possible based on the given information.
4. From the cross, the percentage of offspring expected to be Libb is 50%.
5. The percentage of offspring expected to be 11Bb is 0% since the genotype 11Bb is not possible based on the given information.
6. The percentage of offspring expected to be libb is 0% since the genotype libb is not possible based on the given information.

The possible gametes from a doe with the genotype Libb are LB and Lb.
