What is the expected phenotype of F1 progeny from a cross between two homozygous recessive mutants disrupted in different genese
LenaWriter [7]

Answer:

The correct answer would be - wildtype.

Explanation:

Let assume there are four genes which are :

A-B-C-D

In mutant first, the genotype would be:---a-b-C-D

In the mutant second, the genotype would be:--A-B-c-d

If both of these genotypes are crossed with each other, the recessive genes a, b of mutant first is dominated and masked the expression by the dominant genes present in the mutant second.
