Question

6) In fruit flies, red eyes are dominant (E). White eyes are recessive (e). If the female fly has white eyes and the male fly has homozygous dominant red eyes, what are the possible phenotypes and genotypes of their offspring?

Genotypes:
EE:
Ee:
ee:
Phenotypes:
Red Eyes:
White Eyes:​

Answer 1

Step-by-step explanation:

Here we have to cross

• Male : Red eyes ( homozygous dominant)
• Female: white eyes .

The genotype of the male fruitfly will be w+w+ and for female it will be ww .

For cross refer to the attachment.

From the cross,

• Genotype of all oppsprings =
  `\bf w^+ w`
• Phenotype= Red eyes in all oppsprings.
