sex chromosome

Karyotype reveal that in most cells all but sex chromosomes are present as two copies, referred to as homologous pairs.

The only biological certainty is that the differing sex chromosomes almost invariably result in differing reproductive kit and body shape.

In diploid cells, there is a pair of sex chromosomes; the remainder are termed autosomes .

Failure of the butterfly's sex chromosomes to separate during fertilisation is behind this rare sexual chimera.

This works for diploid plants, but numerous plant species are polyploid and must therefore have multiple sex chromosomes.

But sometimes a person has an abnormal number of sex chromosomes, which can result in various disorders that range in severity.

Choose your towel by the applicable set of sex chromosomes.

Heterogametic sex The sex with dissimilar sex chromosomes, one (in mammals the Y chromosome)being shorter than the other(the X chromosome).

Sex chromosomes normally contain much less genetic information.

Homogametic sex The sex with homologous sex chromosomes, in mammals, designated XX.

A complicated chain triggered by temperature in the gecko, by sex chromosomes in humans.

Wang and his team found that sex chromosomes did play a role in meiosis.

In people, females have two X (sex) chromosomes, while males have one X and one Y.

When it comes to sex chromosomes, women are XX and men are XY.

The researchers revealed the animal has 52 chromosomes, including 10 sex chromosomes.

But unlike humans, the X and Y are not sex chromosomes.

Autosomes Paired somatic chromosomes that play no part in sex determination. Compare sex chromosomes.

They can also occur when an egg with two sex chromosomes, instead of a single one, gets fertilized by two sperm.

One pair are called the sex chromosomes because they contain genes that determine sex.
