Question
If a cross is made between AA and aa, the genetic nature of F1 progeny will be:Select an answerAAABAaCaaDAaAa
Solution
The genetic nature of F1 progeny from a cross between AA and aa will be Aa. This is because each parent contributes one allele to the offspring. The AA parent will contribute an A allele and the aa parent will contribute an a allele. Therefore, the F1 progeny will be heterozygous (Aa). So, the correct answer is D. AaAa.
