Half the chromosomes are inherited from the father and the other half from the mother. There are 2 types of sex chromosomes - X and Y. An individual with one X and one Y sex chromosome will usually have male body parts. The X and Y chromosomes also known as the sex chromosomes determine the biological sex of an individual.

Males normally have one X and one Y chromosome. Thus females are XX and males are XY. The equivalent situation females who have XY instead of XX chromosomes can occur for a variety of reasons and overall is similar in frequency. Numerous studies show XXY boys and men possess the same capabilities as XY boys and men.

XXY men are identical in physical appearance and mental capacity to XY men. However one of the X chromosomes is inactivated. A chromosome is a strand of DNA. By University of Montreal.

The chromosomes contain genes which determine an individuals characteristics such as eye color and height. In human thought the body that appears to have external genital organs has been named male in modern times has been found to usually have a Y to match the X and is expected to follow a certain life style while those without this are called female usually have two X chromosomes and are expected to foll Continue Reading. XXY male. XX male syndrome also known as de la Chapelle syndrome is a rare congenital intersex condition in which an individual with a 46 XX karyotype otherwise associated with females has phenotypically male characteristics that can vary among cases.

Through this mechanism we understand that X chromosomes will regulate female while Y is male. It is the presence of this Y chromosome that determines a persons biological sex. In humans and other mammals most insects eg Drosophila and many plants eg Coccinia Melandrium females have two X-chromosomes XX whereas males have one X and a morphologically distinct Y-chromosome XY. The male Y chromosome does more than we thought.

The Superman syndrome occurs when males receive an extra Y chromosome at conception creating an XYY combination. Female mammals have two X chromosomes in every cell. New light is being shed on a little-known role of Y chromosome genes specific to. Biologically male people always inherit their X chromosome from their mother.

Y-chromosome though different in size and shape pairs with X during meiosis. Females inherit an X chromosome from the father for a XX genotype while males inherit a Y chromosome from the father for a XY genotype mothers only pass on X chromosomes. It is caused by the presence of an extra Y chromosome. Females have two X chromosomes while males have one X and one Y chromosome.

Women have 22 normal chromosomes and 2 X chromosomes ie 22 XX and men have 22 normal chromosomes and 1 X 1 Y ie 22 XY.

The presence or absence of the Y chromosome is critical because it.

They determine the biological sex reproductive organs.

The X and Y chromosomes commonly referred to as the sex chromosomes are one such pair. Affected individuals are usually very tall. The X chromosome is about three times larger than the Y chromosome containing about 900 genes while the Y chromosome has about 55 genes. XYY syndrome is a rare chromosomal disorder that affects males.

This means that in the United States there are about 7500 men without a Y chromosome. Boys typically have one X chromosome and one Y chromosome or XY but boys with XYY syndrome have an extra Y chromosome or XYY.
