Answer to Question #214550 in Genetics for moe

Question

2.6) Albino mice lack pigment in their fur and eyes, Hybrids between pure coloured and pure albino mice are coloured (heterozygotes). If coloured and albino are alternatives for the gene locus, then:

• Is the albino or coloured allele dominant?

• What frequency of albino progeny (offspring) is expected from the crosses between heterozygous coloured mice?

• What types of progeny are expected if albino mice are mated?

• Why can’t you make an exact prediction of the types of progeny if coloured mice are mated?
