Question
Which cross will produce only heterozygous offspring?Aa × aaAA × AaAa × AaAA × aa
Solution
The cross that will produce only heterozygous offspring is AA × aa.
Here's the step by step explanation:
-
AA represents a homozygous dominant individual, meaning both alleles for a particular trait are the same and dominant (A).
-
aa represents a homozygous recessive individual, meaning both alleles for a particular trait are the same and recessive (a).
-
When these two individuals cross, the only possible combination for the offspring is Aa, which is heterozygous (meaning the two alleles for a particular trait are different).
So, all offspring from this cross will be heterozygous (Aa).
