The element responsible for determining male sex in humans is the Y chromosome.
Yes, individuals with Down syndrome have an X chromosome, just like everyone else. Down syndrome is typically caused by the presence of an extra copy of chromosome 21, resulting in three copies instead of the usual two. This condition is not directly related to the X chromosome, which is one of the sex chromosomes involved in determining biological sex. Both males and females with Down syndrome have one X chromosome and one Y chromosome (for males) or two X chromosomes (for females).
The female sex chromosome, known as the X chromosome, plays a crucial role in determining the biological sex of an individual. Females typically have two X chromosomes, while males have one X and one Y chromosome. The presence or absence of the Y chromosome determines whether an individual develops as male or female.
Autosomes and sex chromosomes are both types of chromosomes found in the nucleus of cells. The main difference is that autosomes contain genes responsible for determining most traits, while sex chromosomes determine an individual's biological sex. Additionally, humans typically have two sets of autosomes (one from each parent) and one pair of sex chromosomes (XX for females and XY for males).
It doesn't. We all have X chromosomes.
That would be the chromosome number 23. Regarding the [sex] chromosome number 23, the female gametes always have a [haploid] X chromatid, whereas the male gametes are just as likely to possess a [haploid] X chromatid as they are to possess a [haploid] Y chromatid.
Autosomes are chromosomes that are not involved in determining the sex of an organism; they typically carry genes that influence a wide range of traits. In humans, there are 22 pairs of autosomes. In contrast, sex chromosomes are specifically involved in determining the sex of an individual, with humans having one pair: XX for females and XY for males. This distinction is crucial in understanding genetic inheritance and the expression of certain traits.
