In mice, having hairs (A) is dominant over being hairless (a) and white color (D) is dominant over black color (d). Scientists performed an experiment in which they crossed a hairless black female mice with a heterozygous for both traits male mice.

1.)What is the male mice's phenotype?

2.)The male has a genotype of AaDd. What is the genotype for the female?

3.)What are two possible genotypes for a hairless white mice?

4.) What is the possibility of having a white mice? Write answer as a percentage.

Purple flowers (P) are completely dominant over white flowers (p) in pea plants. A plant that is heterozygous for purple flowers (male) is crossed with another plant that has white flowers (female). Use a Punnett square to determine the expected genotypic and phenotypic ratios for the offspring. What is the purple pea plant's genotype? What is the white pea plant's genotype? What are the purple pea plant's gametes? What are the white pea plant's gametes? What is the expected genotypic...

In cattle, roan color (mixed red and white hairs) occurs in the heterozygous (Rr) offspring of red (RR) and white (rr) homozygotes. When two roan cattle are crossed, the phenotypes of the progeny are found to be in the ratio of one red: two roan: one white. Which of the following crosses could produce the highest percentage of roan cattle? a) red x white; b) roan x roan; c) white x roan; d) red x roan e) all of the...

3a. In a certain breed of dog long hair is dominant over short hair; the gene involved is autosomal. Another gene, B controls hair colour, which is X-linked, one allele B1 produces gray coloured hair; the other allele B2 produces red coloured hair; and the heterozygous combination B1B2 produces brindle coloured hair (a mix with patches of both gray and red coloured hairs). If a red male homozygous for long hair is mated with a brindle short-haired female, what kind...

Simple Dominance with 2 genes A gene in cats causes them to be black (dominant) or brown (recessive). A second gene causes cats to be agouti (have stripes on their hairs) or non-agouti (solid colored hairs). If you did a dihybrid cross between two black haired agouti cats, what fraction of the offspring would be expected to have each phenotype? If a dihybrid black agouti cat mated with a brown cat that was heterozygous for the agouti gene, what fraction...
