In a karyotype chromosomes are distinguished by number, size and centromere position. This is obtained by certain staining methods. The G method (geimsa staining) indicating the banding pattern of the chromosome by light and dark staining of the bands which are unique to each chromosome or by the Q method (quinicrine fluorescence) where bands indicate fluorescently that are Adenine and Thiamine rich. Other methods are the R method (reverse banding) where chromosomes are first heated before being geimsa stained and indicate in reverse to that of the G method, and the C method (centromeric heterochromatin) involving the staining of the centromere.

What chromosomes typically make up the sex chromosomes in a human male, and how do they determine the individual's biological sex?
The sex chromosomes in a human male typically consist of one X chromosome and one Y chromosome. The presence of a Y chromosome determines the individual's biological sex as male, while the absence of a Y chromosome results in a female biological sex.
What are chromosomes that determine the sex of a child?
There are two kinds of sex chromosome X and Y that result in two different sex types: XX in females and XY in males. A child will always get a X chromosome from their mother, but the sex depends on which chromosome the male gives, which is completely random, you could get the X chromosome making you female or you could get the Y chromosome making you male.
What are sex chromosomes and how do they determine an individual's biological sex?
Sex chromosomes are a pair of chromosomes that determine an individual's biological sex. In humans, females typically have two X chromosomes (XX), while males have one X and one Y chromosome (XY). The presence of the Y chromosome triggers the development of male characteristics, while the absence of the Y chromosome results in the development of female characteristics.
What is a sex chromosome and how does it determine an individual's biological sex?
A sex chromosome is a specialized chromosome that carries genes related to determining an individual's biological sex. In humans, females typically have two X chromosomes (XX) and males have one X and one Y chromosome (XY). The presence of a Y chromosome triggers the development of male characteristics, while the absence of a Y chromosome results in the development of female characteristics. This genetic combination determines an individual's biological sex.
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.
One pair of chromosomes that determine the sex of an individual?
sex chromosome
What determine the sex of a human being?
Whether they have 2 X chromosomes= girl, of one X chromosome and one Y chromosome= boy
Explain how the sex chromosomes determine the sex of the offspring?
The sex chromosomes inherited from the parents determine the sex of the offspring. Females have two X chromosomes (XX), while males have one X and one Y chromosome (XY). The presence of a Y chromosome results in the development of male characteristics, while the absence of a Y chromosome leads to the development of female characteristics.
In humans what are the chromosome pairs 1 through 22 called?
Chromosome pair 23 in humans is the pair of sex chromosomes. In females, both sex chromosomes are the X sex chromosome, and in human males one sex chromosome is the X and the other is the Y chromosome.
What chromosomes typically make up the sex chromosomes in a human male, and how do they determine the individual's biological sex?
The sex chromosomes in a human male typically consist of one X chromosome and one Y chromosome. The presence of a Y chromosome determines the individual's biological sex as male, while the absence of a Y chromosome results in a female biological sex.
Men have one of y?
The y chromosome. The chromosome pair that determine sex (gender) can have x and y chromosomes; men have one X and one Y chromosome, women have to X chromosomes.

How sex is determined in Valanga Sp with regard to its chromosome?
Valanga sp. sex is determined by using the XO system. This system use only one type of sex chromosome, the X. Females are XX while males have only one sex chromosome (XO). Sex of the offspring is determined by whether the sperm cell contain and X chromosome or no sex chromosome.

What is X chromosome?
The x chromosome is one of the sex chromosomes, the other being the y chromosome. In mammals there are two of the sex chromosomes in each organism. Females generally contain two x chromosomes, and males contain one x chromosome and one y chromosome.
