Answer:
The correct genotypic ratios for the F1 progeny is 1 round eyes : 1 raisin eyes (Option c)
Explanation:
<u>Available data:</u>
- round eyes (rai+) are dominant to raisin eyes (rai)
- round eyes are found in wild-type flies,
- raisin eyes are the result of a mutant allele
Cross: A heterozygous parent (rai+ rai) is crossed with a homozygous recessive parent (rai rai)
Parental) rai+ rai x rai rai
Gametes) rai+ rai rai rai
Punnet square) rai+ rai
rai rai+ rai rai rai
rai rai+ rai rai rai
F1) Progeny genotype: 2/4= 1/2 rai+ rai, round-eyed individuals
2/4=1/2 rai rai, raisin-eyed individuals
The correct genotypic ratios for the F1 progeny is 1 round eyes : 1 raisin eyes
