White eyes are recessive in flies. can two red eyed flies have white eyed offspring

Considering that white eyes are a recessive trait in flies, it is possible for two red-eyed flies to have offspring with white eyes only if both are heterozygous for this trait.

Explanation:

For two individuals with dominant phenotype for a trait to have offspring with the recessive trait, both must have a heterozygous genotype.

In the case of the characteristic eye color of the flies :

Red eye (R) is dominant trait. White eyes (r) is the recessive trait.

When both parents are heterozygous, their genotype is Rr

In Punnett Square it can see the result of the crossing of these individuals:

Punnett Square :

Rr X Rr

Alleles     R     r

R              RR   Rr

r               Rr    rr

In the offspring, the probabilities are:

50% heterozygous individuals Rr, with red eye phenotype. 25% pure dominant individuals RR, with red eyes 25% individuals with the recessive rr genotype, white eyes.

This is the possibility of two red-eyed flies having white-eyed offspring.

Explanation:

The neuroconstructivist states that the gene and environment interactions are crucial for the development of the brain and provide us with distinct evolutionary functions. These gradually become specialized over a period of time.
