Q4.5. A scientist came across two populations of beetle species, each pure-breeding. One population was all red in color; the other was all black. The scientist mated one red beetle with one black beetle, and the offspring were all red. What is the dominance relationship between the two alleles? Black is dominant over red. Red is dominant over black. Black and red are codominant. More crosses are needed to determine the dominance relationship.

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.
