Answer:
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.
