You are attempting to map the chromosome of a silk moth. You know that red eyes and white banded wings are recessive to the wild type eyes and wings. You cross a homozygous recessive moth with a homozygous dominant moth. The f1 generation has all wild type traits. You then allow the f1 progeny to interbreed and acquire the following numbers: Wild type eyes and wild type wings -418 Red eyes and wild type wings -16 Wild eyes and white banded wings- 16 Red eyes and white banded wings - 426 Determine the recombination frequency of Red eyes and white banded genes. Also, determine the distance between them.

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.
