Answer:
The scientist is correct in stating that the genotype of person B is Ff based on the information provided.
Step-by-step explanation:
Genotype refers to the genetic composition of an individual, specifically the combination of alleles they possess for a particular gene. In this case, the gene being referred to is represented by the letter "F."
The genotype of person B is stated to be Ff, which indicates that person B carries two alleles for the gene. In genetics, uppercase letters typically represent dominant alleles, and lowercase letters represent recessive alleles.
Therefore, with the genotype Ff, we can deduce that person B has one dominant allele (F) and one recessive allele (f) for the gene in question. This suggests that person B is heterozygous for the gene, meaning they inherited one copy of the dominant allele from one parent and one copy of the recessive allele from the other parent.
It's important to note that without additional information or context, we cannot definitively determine the precise genetic makeup of an individual. However, based on the given statement, the scientist's assertion that person B's genotype is Ff is plausible.
