In fruit flies, gray is dominant over ebony body color and wild is dominant over curled wings.  A heterozygous gray, normal female is crossed with an ebony, curled male and the following results were obtained:                         gray, normal        98                         gray, curled       106                         ebony, normal   101                         ebony, curled      97             Based on these data, are these two loci linked? Fully explain your answer.

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.
