Please be sure to answer each part of the question below
The allele for brown eyes is dominant and represented by the letter E. 1. How would the recessive allele be represented? 2. Please look at the image provided of the mother and father then look at the image of their child. Is this outcome possible? If so, can you explain how it could occur? In two to five sentences use lesson vocabulary and content to explain your answer. 3. Make sure you include the parent's and child's genotypes in your answer.
You may use the following word bank: parent, offspring, allele, genotype, recessive, dominant, heterozygous, homozygous, and phenotype.
Mom has brown eyes
Dad has brown eyes
Child has blue eyes
1. The recessive allele for brown eyes would be represented by the lowercase letter e.
2. No, this outcome is not possible. Since brown eyes are dominant and both parents have brown eyes, the child must inherit at least one dominant allele for brown eyes. This means that the child's genotype must be either homozygous dominant (EE) or heterozygous (Ee) for brown eyes. Therefore, it is not possible for the child to have blue eyes.
3. Based on the given information, the parent's and child's genotypes can be deduced. Since both parents have brown eyes, they must have at least one dominant allele for brown eyes. Therefore, their genotypes could be either homozygous dominant (EE) or heterozygous (Ee). As for the child, given that the child has blue eyes, the child's genotype must be homozygous recessive (ee).
