To determine the percentage of offspring that resemble the parents, we need to know more about the genetic scenario in question, such as whether the trait is dominant or recessive and the genotypes of the parents.
Here’s a brief overview based on different scenarios:
1. **If both parents are homozygous for a trait (e.g., both are dominant traits):** 100% of the offspring will look like the parents.
2. **If one parent is homozygous dominant and the other is homozygous recessive:** 100% of the offspring will look like the dominant parent.
3. **If both parents are heterozygous (e.g., Aa x Aa):** 75% of the offspring will show the dominant trait, whereas 25% will show the recessive trait.
4. **If one parent is heterozygous (e.g., Aa) and the other is homozygous recessive (aa):** 50% of the offspring would look like the dominant trait.
Given the options and without specific parent genotype information, the best answer might generally depend on multiple interpretations depending on the intended context of the question. However, often 75% is a common result in simple Mendelian inheritance scenarios involving dominant traits.
So, based on a standard Mendelian cross involving a dominant trait, **D (75%)** is a common answer regarding how many offspring look like at least one of the parents if both are heterozygous for a given trait.
