An individual with contrasting alleles is called

Correct answer: C. Heterozygous

  • A. Homozygous
  • B. Monoecious
  • C. Heterozygous
  • D. Dioecious

Explanation

An individual with contrasting alleles is called Heterozygous. This means that the organism has two different alleles (such as Tt) for a particular trait, allowing for genetic variation. The term Homozygous refers to having identical alleles (such as TT or tt), which does not involve contrasting alleles. Monoecious and Dioecious are terms related to the reproductive structures of organisms and do not pertain to allelic composition.

About Mendel's Laws of Inheritance

Mendelian inheritance explains how alleles separate into gametes and assort during reproduction, producing predictable genotype and phenotype ratios. Questions cover dominance, recessiveness, homozygous and heterozygous conditions, the laws of segregation and independent assortment, monohybrid and dihybrid crosses, test crosses and the limits caused by linked genes.
