The Y chromosome is larger and carries fewer genes than the X chromosome?

No. The Y chromosome is much smaller than the X chromosome. There are only about 70 active genes on the Y chromosome and many more deleteriously mutated one. The X chromosome contains many more active genes and only crosses over marginally with the Y chromosome.

Only some of the genes located on the X chromosome control female sexual characteristics.

∙ 16y agoIt is said that the Y chromosome used to be just a component of the X chromosome whic has broken off. That is why it is smaller.
Wiki User
∙ 15y agoThe X chromosome is much larger; about 2,000 genes compared to the Y chromosome which contains only about 50 genes.

∙ 11y agoNo x and y chromosomes have both 24 pairs in humans
Wiki User
∙ 10y agoNo, it is the X chromosome which is larger than the Y chromosome. The X chromosome also has more genes than the Y chromosome.

Which chromosomes carries the fewest numbers of genes?
The y chromosome, which only contains a few hundred genes.
If a characteristic is sex-linked then where is the gene for it found?
Genes for sex-linked traits can be found on the sex chromosomes - X and Y. Almost all sex-linked traits are determined by the X chromosome, because it is much larger than the Y chromosome and can thus carry more genes. A few sex-linked traits are known on the Y chromosome, including - believe it or not - hairy ears.
Is there more genes located on female sex chromosomes then on the male sex chromosome?
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.
Which trait will a male exhibit if he carries a recessive allele on the X chromosome?
A male carrying a recessive allele on the X chromosome will exhibit the recessive trait. This is because the Y chromosome generally does not have matching genes for the X chromosome, unlike the other 22 pairs if chromosomes in the nucleus.
What part of a chromosome carries information and controls a trait?
genei think its in the genetic code that comes from the order the bases are in on a strand of DNA the DNA is in a gene witch is in a chromosome
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
How do X and Y chromosome differ?
men have a x and y chromosome while women have two x chromosomes the y chromosomes determine the sex of the baby
What is larger a nucleosome or chromosome?
A chromosome is made up of many genes.
If a characteristic is sex-linked then where is the gene for it found?
Genes for sex-linked traits can be found on the sex chromosomes - X and Y. Almost all sex-linked traits are determined by the X chromosome, because it is much larger than the Y chromosome and can thus carry more genes. A few sex-linked traits are known on the Y chromosome, including - believe it or not - hairy ears.
Is a chromosome larger than a gene?
There are 25,000 human genes on 23 chromosomes. There are hundreds of genes on the smaller chromosomes and thousands on the bigger ones.
What is the name of genes that are carried on the same chromosome?
The genes that are carried on the same chromosome are called as the linked genes.
Is there more genes located on female sex chromosomes then on the male sex chromosome?
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.
What chromosomes are sex linked genes located?
The sex chromosomes, mostly on the X sex chromosome because it is much larger than the Y chromosome and has more alleles.
Which trait will a male exhibit if he carries a recessive allele on the X chromosome?
A male carrying a recessive allele on the X chromosome will exhibit the recessive trait. This is because the Y chromosome generally does not have matching genes for the X chromosome, unlike the other 22 pairs if chromosomes in the nucleus.
