Yes and no to the question above. Yes to the comparison you probably intended between X and Y, not XX and XY.
The X chromosome is far larger than the Y chromosome. Therefore to the question above, the total number of genes is greater for XX than for XY but XY carries more variety because it has two distinct sets of genes whereas XX only repeats itself.
Chromosomes contain genes, which are the units of inheritance that carry genetic information. Genes are located on specific locations on chromosomes, known as gene loci. Each chromosome carries hundreds to thousands of genes that determine an individual's traits and characteristics.
The chromosome that carries the genes determining the sex of a child as male or female is the X and Y chromosomes. Males have one X and one Y chromosome, while females have two X chromosomes.
Sex linked genes are located on the sex chromosomes.
Yes, not all genes located on the X chromosome control female sexual characteristics. The SRY gene on the Y chromosome is responsible for male sexual development. However, genes on the X chromosome like the XIST gene are involved in the regulation of X chromosome inactivation, a process critical for normal development in females.
Genes located on the X or Y chromosome are referred to as sex-linked genes. This is because the inheritance of these genes is dependent upon the sex of the individual. For example, only males can inherit genes located on the Y chromosome (because males have XY and females have XX).
Genes are located within every chromosome.
genes located on sex chromosomes are called sex-linked genes. In humans, there are two types of sex chromosomes: X and Y chromosomes.Genes located on the X chromosome are called X-linked and genes located on the Y chromosome are called Y-linked chromosomes.

Yes, not all genes located on the X chromosome control female sexual characteristics. The SRY gene on the Y chromosome is responsible for male sexual development. However, genes on the X chromosome like the XIST gene are involved in the regulation of X chromosome inactivation, a process critical for normal development in females.
Genes in the X chromosome of males are always expressed because males have only one X chromosome, so there is no second copy to mask the expression of genes. This is different from females, who have two X chromosomes and undergo a process called X inactivation to balance gene expression between the X chromosomes.
The dumpy and sepia genes are both genes for the house fly, Drosophilia. These genes appear on the third chromosome.
Genes located on the X or Y chromosome are referred to as sex-linked genes. This is because the inheritance of these genes is dependent upon the sex of the individual. For example, only males can inherit genes located on the Y chromosome (because males have XY and females have XX).
No. The human cell has 23 chromosome pairs (total 46 chromosomes). Each chromosome has many genes.
