Both genders usually have 2 sex chromosomes. Females have two X chromosomes and males typically have an X and a Y. Since a male can give an X and a Y, it is the male who determines the gender of the fetus.
Now there are variations because of chromosomal and genetic errors and differences. A woman with Turner's Syndrome has just one X chromosome, and a man with Kleinfelter's syndrome has two X chromosomes in addition to his Y chromosome. There are also women with three X chromosomes and men with a X chromosome and two Y chromosomes. Then, with CAIS, there are sterile XY females, and there is Fragile X Syndrome where a female has an X chromosome with portions of it missing, so it may look like a Y.
XY and female has YY
21
x,y
x and y
Males have 44 homologous chromosomes, or 22 pairs. Females are 46 and 23 respectively since they have homologous sex chromosomes.
Males have both X & Y chromosomes
XY Chromosomes = Males XX Chromosomes = Females
Humans have 46 chromosomes, with 22 pairs of autosomes and 1 pair of sex chromosomes. Males have XY sex chromosomes while females have XX sex chromosomes. However, genetic disorders do occur whereby some males have XYY or XXY chromosomes, making the total number of chromosomes to be 47. Females have their own share of genetic disorders: Turner's Syndrome (single X chromosome) or Trisomy X (XXX). In normal cases the short answer would be: XY for males, XX for females.
Human females have two X chromosomes (XX) while human males have one X and one Y chromosome (XY). This difference in sex chromosomes determines biological sex and leads to different developmental pathways in males and females.
Female have two X chromosomes while males have an X and a Y chromosome.
in cells are diffrnet from chromosomes do not grow up.
No. This is a myth resulting from the fact that the majority of biological females have XX chromosomes and the majority of biological males have XY.For example, there are males with XX chromosomes (see https://en.wikipedia.org/wiki/XX_male_syndrome)There are also many other variations.
Humans have two sex chromosomes, the X and the Y. Human females have two X sex chromosomes and are said to be XX. Human males have one X and one Y chromosome and are said to be XY.
the sex chromosomes. females are XX and males XY. the males chromosmes is where onewould find the difference
Each human normally has 46 chromosomes separated into 23 pairs. In males, the 23rd "pair" is not really a pair since males have an X and a Y sex chromosome.
The 22 pairs of chromosomes in human somatic cells that are same in males and females are called autosomes.
