Question

Answer the following. Letters only. 1. In mice, black color (B) is dominant over brown (b), and a solid pattern (S) is dominant over white spotted (s). Color and spotting are controlled by genes that assort independently. A homozygous black, spotted mouse is crossed with a homozygous brown, solid mouse. All the F1 mice are black and solid. What are the genotypes of the parents? * a. BBSs and bbss b. BBSs and bbSS c. BbSs and bbSs d. BBss and bbss e. BBss and bbSS f. None of the choices 2. In mice, black color (B) is dominant over brown (b), and a solid pattern (S) is dominant over white spotted (s). Color and spotting are controlled by genes that assort independently. A homozygous black, spotted mouse is crossed with a homozygous brown, solid mouse. All the F1 mice are black and solid. What will be the genotypic probability of the first filial (F1) generation offspring? * a. 100% BBSS b. 100% BbSs c. 50% BBSS and 50% BbSs d. 25% BBSS; 50% BbSs and 25% bbss e. 100% black, solid mice f. None of the choices 3. In mice, black color (B) is dominant over brown (b), and a solid pattern (S) is dominant over white spotted (s). Color and spotting are controlled by genes that assort independently. A homozygous black, spotted mouse is crossed with a homozygous brown, solid mouse. All the F1 mice are black and solid. A test cross is then carried out by mating the F1 mice with brown, white spotted mouse. What will be the probability of having brown, solid mice offspring (F2 or second filial generation)? * a. 25% b. 50% c. 75% d. 100% e. 0% f. none of the choices 4.

A homozygous black, spotted mouse is crossed with a homozygous brown, solid mouse. All the F1 mice are black and solid. A test cross is then carried out by mating the F1 mice with brown, white spotted mouse. What will be the probability of having heterozygous black and white spotted mice offspring (F2 or second filial generation)? * a. 25% b. 50% c. 75% d. 100% e. 0% f. none of the choices 5.
