According to the Law of Segregation, how many alleles are passed from each parent during reproduction?

• A. One
• B. Two
• C. Three
• D. Four

Answer: (A)

The correct response is based on the Law of Segregation, a fundamental principle of genetics proposed by Gregor Mendel. This law states that during the formation of gametes—sperm and egg cells—each parent contributes only one allele for each gene. The alleles that segregate are the different forms of a gene that may exist. For example, if a parent has two alleles for a trait (like flower color), during gamete formation, only one of those alleles will be passed on. This ensures that offspring inherit one allele from each parent, leading to the potential for a combination of alleles in the offspring, which may result in varied traits. Therefore, one allele is passed from each parent, making the answer accurate in reflecting this genetic principle.
