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.

How are autosomes similar to sex chromosomes?
Sex chromosomes and autosomes are from the same chromosome, The chromosome has 46 chromosomes and 2 of them are sex chromosomes and the rest are called autosomes
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.

In humans what are the chromosome pairs 1 through 22 called?

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.
Explain how the sex chromosomes determine the sex of the offspring?

Chromosome that determine the sex of an individual are called?
Parent Cells
What is the difference between an autosome and a sex chromosome?
An autosome is any of the 23 chromosomes which is not an X or Y chromosome. A sex chromosome is effectively the same as an autosome, apart from depending upon whether you inherit a Y chromosome or not, a sex chromosome will determine your gender. Hence the name.
