In mice, the dominant allele Gs of the X-linked gene Greasy produces shiny fur, while the recessive wild type Gs+ allele determines normal fur. The dominant allele Bhd of the X-linked Broadhead gene causes skeletal abnormalities including broad heads and snouts, while the recessive wild-type Bhd+ allele yields normal skeletons. Female mice heterozygous for the two alleles of both genes were mated with wild-type males. Among 100 male progeny of this cross, 49 had shiny fur, 48 had skeletal abnormalities,...

1) (4 pts) Black hair in rabbits is determined by a dominant allele, B, and white hair by homozygosity for a recessive allele, b. Two heterozygous rabbits mate and produce a litter of seven offspring. With what frequency would we expect to find: a) four whites and three black offspring? b) one white and six black offspring?

The dominant allele of gene A encodes for long ears in rabbits whereas the recessive allele encodes for short ears. The dominant allele for gene B encodes for pointy ear tips while the recessive encodes for round tips. Genes A and B are 70 map units apart. A rabbit with AB/ab genotype is test crossed. What phenotypic ratios do you expect to see in the F1? Select one: a. 3 long and pointy : 1 short and round b. 20...

1.) Black hair in rabbits is determined by a dominant allele, B, and white hair by homozygosity for a recessive allele, b. Two heterozygous rabbits mate and produce a litter of five offspring.

In some mice, black fur (B) is dominant to white (b). At a different locus, a dominant allele (A) produces a band of red just below the tip of each hair. The expression of the recessive allele (a) results in solid coat color. If rabbits that are heterozygous at both loci are crossed: -what proportion of their offspring is expected to have a solid color? -what proportion of their offspring is expected to be white with a red band? -what...
