Thus, he first performed a test cross between the white-eyed male fly and several purebred, red-eyed females to see whether white eyes might also occur in the next generation. The F1 flies both male and female were all red-eyed indicating that white eye colour is recessive to the normal red eye colour. A daughter on the other hand will always be a carrier some of which may present with symptoms due to aforementioned skewed X-inactivation , unless the condition is dominant, in which case she will always be affected. In birds and butterflies the sex chromosomes Z and W are also unequal in shape and size, Z being larger than W. Since humans have several times as many genes on the female X chromosome than on the male Y chromosome , X-linked traits are much more common than Y-linked traits. Homologous chromosomes have the same genes arranged in the same order. A character from father goes to daughter F1 and then from daughter to grandson in the next generation F2. A red eye and mutant white eye in Drosophila. One gene on the Z chromosome affects feather color ; three different alleles make feathers blue, ash-red, or brown. Vascular plants show a variety of sexual arrangements. In other words, character is transferred from mother to the son and never from father to the son. Male birds make sperm, which always have a Z chromosome.

    In classical genetics , a mating experiment called a reciprocal cross is performed to test if an animal's trait is sex-linked. Since humans have several times as many genes on the female X chromosome than on the male Y chromosome , X-linked traits are much more common than Y-linked traits.
