Question

A dihybrid tall plant bearing yellow flowers was crossed with a dwarf plant bearing white flowers. What is the percentage of progeny expected to be homozygous tall bearing yellow flowers?

• A. $0\%$
• B. $25\%$
• C. $50\%$
• D. $75\%$

Answer 1

The correct option is A $0\%$

A dihybrid tall plant bearing yellow flowers was crossed with a dwarf plant bearing white flowers, to give heterozygous offspring showing tall height and yellow flowers. But, none of the offsprings will be homozygous for the tall height allele along with yellow flower allele.

So, the correct option is '0%'.
