Consider the following linked traits in fruit flies:       V= vermillion eyes (v+ is red eyes)       cv = crossveinless wings (cv+ have crossveins)       ct = cut wing margins (ct+ have uncut margins)   You perform the following cross: v+v+ cv+cv+ ct+ct+       x    vv cvcv ctct   You then cross an F1 fly with a fly recessive for all three traits: v+v cv+cv ct+ct    x    vv cvcv ctct   These are the offspring you observed from this cross:   Red, crossveins, uncut 580 Vermillion, crossveinless, cut 592 Red, crossveinless, cut 89 Vermillion, crossveins, uncut 94 Red, crossveinless, uncut 45 Vermillion, crossveins, cut 40 Red, crossveins, cut 3 Vermillion, crossveinless, uncut 5   Draw a map of these 3 genes on the fly chromosome they inhabit.

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.
