Projection

The Two Different Means of Achieving Dosage Compensation for X-linked Genes Employed by Drosophila awed with one dose, while the female receives two doses of the euchromatic region of the X. During the course of evolution of this insect, the dosage compensation mechanism must have developed one by one for each individual X-linked gene.

Three Different Consequences of X-autosome Translocationers ranging from a high of 80 to a low of 17. This indicates that during extensive speciation from a common ancestor, autosomal linkage groups have undergone countless rearrangements. Yet, the original X-chromosome of a common ancestor has apparently been preserved in its entirety by a great majorit

The Consequences of Y-autosome Translocation and the XO as the Normal Female of Certain Mammalian Spn does not handicap bearers of X-autosome translocation. This type persisted in certain species and produced the XY.Y./XX scheme of the sex-determining mechanism. In this chapter, two unusual sex-determining mechanisms which are produced as a result of Y-autosome translocation shall be discussed.

While sex-linked genes are Mendelian genes which behave in a predictable manner, the sex-determining factors are elusive entities which have not permitted close scru

Time and Place of Action of Sex-determining Factors in Ontogenynetic constitutions, different somatic cell types in different parts of the body perform different functions. This is because many of the genes are turned on only in certain somatic cell types. The gene loci for component polypeptides of hemoglobin function only in erythropoietic cells. Skin cells a
