Answer 2

Answer:

25% of ab gametes produced by AaBb parent.

A parent with AaBb alleles or characters will produce the following alleles:

AB Ab aB ab

So there are 4 possible gametes that can be obtained from the AaBb allele, each of which have equal chance or potential of expression. Hence, the percentage of ab gamete produced by
