Which of the following is NOT one of the four related concepts of Mendel's model?

  • A: Alternative versions of genes (alleles) account for variations.
  • B: For each character, an organism inherits two alleles, one from each parent.
  • C: If two alleles differ, the dominant allele determines the appearance.
  • D: Alleles for different characters are always inherited together.

Explanation

This statement is incorrect and describes dependent assortment. Mendel's fourth concept is the law of segregation, which states alleles separate. The law of independent assortment discussed later states that alleles for different characters are inherited independently, not together.
