Question

In a large genetic cross, 50% of the offspring have the dominant phenotype and 50% have the resessive phenotype. What are the most probable geneotypes of the parents used in this cross?

Answer 1

A 25 percent cross between the dominant and resessive geneotypes of the offspring.......Do you own work loser......

Answer 2

When you get two phenotypes in equal numbers, you have probably done a test cross. In a test cross, one parent is heterozygous and the other is homozygous recessive. Try that cross with a Punnett square and see what you get.
