Question

If the heterozygous, Ww, is crossed with a homozygous dominant, WW, then the probability of having a homozygous. Recessive offspring is? .

Answer 1

Answer;

Zero

The probability of having homozygous recessive offspring is Zero.

Explanation;

During expression of traits a dominant allele will mask a recessive allele.

When a heterozygous, Ww, is crossed with a homozygous dominant, WW, the offspring will either be homozygous dominant or heterozygous.

50 percent of the offspring will be heterozygous and 50 percent of the offspring will homozygous dominant.

Since, there will be no offspring that is homozygous recessive then the probability of getting homozygous recessive from the cross is zero.

Answer 2

Answer;

Zero

The probability of having homozygous recessive offspring is Zero.

Step-by-step explanation;

• During expression of traits a dominant allele will mask a recessive allele.
• When a heterozygous, Ww, is crossed with a homozygous dominant, WW, the offspring will either be homozygous dominant or heterozygous.
• 50 percent of the offspring will be heterozygous and 50 percent of the offspring will homozygous dominant.
• Since, there will be no offspring that is homozygous recessive then the probability of getting homozygous recessive from the cross is zero.
