Question

what is the probability of heterozygous offspring?100%50%0%25%punnett square:| | b | b ||---|---|---|| b | bb | bb || b | bb | bb |

Explanation:

Step1: Identify heterozygous genotypes

Heterozygous = $Bb$

Step2: Count total offspring genotypes

Total genotypes: $BB, Bb, Bb, bb$ → $n=4$

Step3: Count heterozygous genotypes

Number of $Bb$: $2$

Step4: Calculate probability

$\text{Probability} = \frac{\text{Number of } Bb}{\text{Total genotypes}} = \frac{2}{4} = 50\%$

Answer:

50%
