Answer :
- Analyze the Punnett square to identify possible offspring genotypes.
- Count the number of heterozygous (Ww) offspring.
- Divide the number of heterozygous offspring by the total number of offspring to find the probability: $\frac{2}{4} = \frac{1}{2}$.
- Convert the probability to a percentage: $\frac{1}{2} \times 100 = \boxed{50\%}$.
### Explanation
1. Analyze the problem
We are given a mating between a heterozygous male (Ww) and a homozygous recessive female (ww). We need to determine the probability that their offspring will be heterozygous (Ww). The Punnett square provided shows the possible genotypes of the offspring.
2. Identify possible outcomes
From the Punnett square, we can see the following possible genotypes for the offspring:
* Ww
* ww
* Ww
* ww
There are a total of 4 possible outcomes.
3. Calculate the probability
Out of the 4 possible outcomes, 2 of them are heterozygous (Ww). Therefore, the probability of an offspring being heterozygous is $\frac{2}{4} = \frac{1}{2}$.
4. Convert to percentage
To express this probability as a percentage, we multiply by 100: $\frac{1}{2} \times 100 = 50\%$.
### Examples
Understanding the probability of inheriting certain traits is crucial in genetics. For example, if you're breeding plants for a specific flower color, knowing the genotypes of the parent plants and the probabilities of different offspring genotypes helps you predict the outcome of the cross and plan your breeding strategy effectively.
