Select the correct answer from each drop-down menu.

If a heterozygous male with the genotype Ww is mated with a homozygous recessive female of genotype ww, there is a chance that the offspring will be heterozygous.

\begin{array}{|c|c|c|}
\hline & w & w \\
\hline w & Ww & ww \\
\hline w & Ww & ww \\
\hline
\end{array}

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

Answer :

Certainly! Let's go through the scenarios step-by-step.

### First Scenario:
We have a heterozygous male with the genotype Ww mating with a homozygous recessive female with the genotype ww.

1. Parent Genotypes:
- Male: Ww
- Female: ww

2. Possible Offspring Genotypes:
- When W from the male combines with w from the female, the offspring is Ww.
- When w from the male combines with w from the female, the offspring is ww.

3. Offspring Genotype Distribution:
- Ww
- ww
- Ww
- ww

4. Probability of Heterozygous Offspring (Ww):
- There are 2 Ww out of 4 possible offspring.
- Therefore, the chance of the offspring being heterozygous (Ww) is 2 out of 4, or 50%.

### Second Scenario:
A heterozygous individual with genotype Ww is crossed with a homozygous dominant individual with genotype WW.

1. Parent Genotypes:
- Heterozygous: Ww
- Homozygous Dominant: WW

2. Possible Offspring Genotypes:
- When W from Ww combines with W from WW, the offspring is WW.
- When w from Ww combines with W from WW, the offspring is Ww.

3. Offspring Genotype Distribution:
- WW
- Ww
- WW
- Ww

4. Probability of Homozygous Recessive Offspring (ww):
- There are no ww genotypes possible in this case.
- Therefore, the probability of having homozygous recessive offspring (ww) is 0 out of 4, or 0%.

In summary:
- The chance of heterozygous offspring in the first scenario is 50%.
- The chance of homozygous recessive offspring in the second scenario is 0%.
