Which chromosomes carries the fewest numbers of genes?
The y chromosome, which only contains a few hundred genes.
Is there more genes located on female sex chromosomes then on the male sex chromosome?
No, the female sex chromosomes (XX) typically have the same number of genes as the male sex chromosomes (XY). The Y chromosome is typically smaller and contains fewer genes compared to the X chromosome.
Which chromosome carries the genes that determine the sex of a child as either male or female?
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.
Most sex-linked genes are found on which chromosome x y?
Many sex-linked genes are found on the X chromosome. More than 100 sex-linked genetic disorders have now been mapped to the X chromosome. The human Y chromosome is much smaller than the X chromosome and appears to contain only few genes.
Is a gene the same thing as a chromosome?
No - genes are sections of DNA found on chromosomes that encode for a functional product (like a protein).Chromosomes are compact structures of DNA and proteins.
How do X and Y chromosome differ?
The X chromosome is larger and carries more genetic information than the Y chromosome. The Y chromosome carries the genes that determine male sex characteristics, while the X chromosome carries genes that are important for both male and female development. Males typically have one X and one Y chromosome, while females have two X chromosomes.
Why does the y chromosome not carry any alleles?
The Y chromosome is smaller than the X chromosome and contains fewer genes. It carries the genes necessary for determining male sex and some other genes, but it lacks many of the genes present on the X chromosome. This is why the Y chromosome does not carry any alleles in the same way that the X chromosome does.
Which chromosomes carries the fewest numbers of genes?
The y chromosome, which only contains a few hundred genes.
What are chromosomes function?
a chromosome carries millions of genes
What is larger a nucleosome or chromosome?
A chromosome is made up of many genes.
Genes that are carried on either the X or the Y chrmosome?
Genes that are carried on the X or Y chromosome are referred to as sex-linked genes. The X chromosome contains a larger number of genes compared to the Y chromosome, which has fewer genes primarily associated with male sex determination and spermatogenesis. Inheritance patterns of these genes can lead to sex-linked traits, such as hemophilia or color blindness, which are often more prominent in males due to their single X chromosome. Traits linked to the Y chromosome, however, are passed from father to son and are less common.
Is there more genes located on female sex chromosomes then on the male sex chromosome?
No, the female sex chromosomes (XX) typically have the same number of genes as the male sex chromosomes (XY). The Y chromosome is typically smaller and contains fewer genes compared to the X chromosome.
Can you live with a y-chromosome and no x-chromosome?
No. The human X chromosome contains over 1000 genes, many of which are essential for life. The Y chromosome in comparison has only about 120 genes. A zygote with Y0 or YY (one or two Y chromosomes) would not be viable.
Which chromosome carries the genes that determine the sex of a child as either male or female?
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.

No - genes are sections of DNA found on chromosomes that encode for a functional product (like a protein).Chromosomes are compact structures of DNA and proteins.
What is true of Y chromosomes?
The Y chromosome is one of the two sex chromosomes in humans, determining male biological sex when paired with an X chromosome. It carries genes that are crucial for male sex determination and spermatogenesis, including the SRY gene, which triggers the development of testes. Unlike the X chromosome, the Y chromosome is much smaller and contains fewer genes, and it is passed from father to son, allowing for paternal lineage tracing. Additionally, the Y chromosome has a higher mutation rate, contributing to genetic diversity among male populations.
