Question
In mice, the yellow coat allele (Ay) is dominant for coat color but acts as a homozygous recessive lethal allele. What phenotypic ratio is expected among the surviving offspring of a cross between two yellow (AyA) mice?
Correct Answer
Option A is the correct answer.
Detailed Explanation
Homozygous AyAy mice die in early embryonic development, altering the classic 3:1 ratio among surviving offspring to 2 yellow (AyA) : 1 agouti (AA).
