Which statement is not part of Mendel's laws as listed?

• A. Genetic linkage
• B. Dominance and Uniformity
• C. Segregation
• D. Independent assortment

Answer: (A)

Mendel's laws describe how traits are inherited and expressed across generations. The laws he outlined include segregation, which says that each individual has two alleles for a gene and these alleles separate during gamete formation so offspring inherit one from each parent; independent assortment, which states that alleles of different genes segregate independently, leading to the classic dihybrid 9:3:3:1 outcome; and dominance with uniformity, where a dominant allele masks the recessive in heterozygotes and the F1 from true-breeding parents is uniform for that trait. Genetic linkage, however, is not one of Mendel's listed laws. It describes how genes that are close together on the same chromosome tend to be inherited together, which means they do not assort completely independently. This concept was discovered after Mendel and shows a limitation of applying strict Mendelian independent assortment to all genes. So the statement about genetic linkage is not part of Mendel's laws as listed.
