Which of the following statements is NOT true according to Mendel's Law of Segregation?

• A. Alleles segregate independently during gamete formation.
• B. Each individual has two alleles for each gene, one inherited from each parent.
• C. Offspring inherit one allele for each trait from each parent.
• D. During gamete formation, the two alleles for a trait separate.

Answer: (A)

Verified step by step guidance

1. Understand Mendel's Law of Segregation: This law states that during the formation of gametes, the two alleles for a trait separate so that each gamete receives only one allele.
2. Review the statement 'Alleles segregate independently during gamete formation': This statement is actually related to Mendel's Law of Independent Assortment, not the Law of Segregation. The Law of Independent Assortment states that alleles of different genes segregate independently of one another during gamete formation.
3. Examine the statement 'Each individual has two alleles for each gene, one inherited from each parent': This is true according to Mendel's Law of Segregation, as each parent contributes one allele for each gene.
4. Consider the statement 'Offspring inherit one allele for each trait from each parent': This is consistent with Mendel's Law of Segregation, as offspring receive one allele from each parent for each trait.
5. Analyze the statement 'During gamete formation, the two alleles for a trait separate': This is a direct description of Mendel's Law of Segregation, confirming its truth.
