Let’s suppose a gene exists as a functional wild-type allele and anonfunctional mutant allele. At the organism level (i.e., at the levelof visible traits), the wild-type allele is dominant. In a heterozygote,discuss whether dominance occurs at the cellular or molecularlevel. Discuss examples in which the issue of dominance dependson the level of examination.

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
