albinism occurs commonly in animal and it is always recessive to the normal pigmentation. six brown and five albino mice born to parents which were likewise brown and albino. what is the genotype of the brown parent?

The genotype of the brown parent would be heterozygous.

Explanation:

As albino is a recessive trait, both the alleles should be recessive for this trait to occur.

A punnet square is a diagram which is made to illustrate the possible genotype of the offsprings.

If the brown parent will be homozygous, then a cross with albino parent  will produce offsprings with brown colour having heterozygous geneotype.

For production of albinos the brown parent should be heterozygous for the trait.

the correct answer is - ability to find a mate
