Part a, Leslie Bohm; part b, Anthony Griffiths. Surface currents, the Ekman spiral, and Ekman transport. The genes on the differential regions of the sex chromosomes show patterns of inheritance related to sex. Inheritance patterns with the other reciprocal cross homozygous recessive female with hemizygous dominant male diverge from the Mendelian pattern more quickly.

Discoveries in fruit fly genetics can be applied to human genetics. Because of the location of the eye-color gene, reciprocal crosses do not produce the same offspring ratios. A daughter will not be affected, but she will have a 50 percent chance of being a carrier like her mother.
The genes on the differential regions of the sex chromosomes show patterns of inheritance related to sex. The sex chromosomes are fewer in number, and, generally in diploid organisms, there is just one pair.
The most famous gene on the Y chromosome is the one that turns on maleness. The fruit has XX and XY sex chromosomes in the female and male respectively. It allows criss-cross inheritance. American biologist, Thomas Hunt Morgan  explain sex-linked inheritance in the fruit fly, Drosophila melanogaster.
The sex chromosomes are one pair of non-homologous chromosomes.
No females have white eyes because they received one of their X-chromosomes from their hemizygous dominant, red-eyed father. In females, the presence of one dominant red encoding allele X W will produce red eyes even if the individual is heterozygous for the white allele.
