In flies, long wings are a dominant trait, and short wings are a recessive trait. Medium wings are the heterozygous trait. Based on this information, if a homozygous long-winged fly is crossed with another a heterozygous fly, their offspring will have which percentages for long, medium, and short wings? Assume random chromosome segregation. A) 25% long, 75% medium, 0% short B) 50% long, 259% medium, 25% short C) 50% long, 50%% medium, 0% short D) 100% medium, 0% long, 0% short

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.
