To determine the percentage of offspring in the F1 generation that are affected by a trait, we need to consider the genetic cross involved (for instance, a monohybrid cross).
– If we have a dominant trait (A) and a recessive trait (a), and we cross two heterozygous parents (Aa x Aa), we would have the following genotype ratios:
– AA: 25%
– Aa: 50%
– aa: 25%
In this case, the offspring that show the dominant trait (AA and Aa) would be 75% (25% + 50%).
So, if this is a typical monohybrid cross with one dominant trait, the correct answer would be 75%.
Answer: 75%
Explanation: In a typical monohybrid cross of heterozygous parents (Aa x Aa), 75% of the offspring would exhibit the dominant trait.
