What are the sex chromosomes that make an individual male?
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.
What combination of chromosomes is a female an a male?
Normal females have XX chromosomes and normal males have XY chromosomes. I believe there are two of each in a human body and the rest are autosomes.
What pair of chromosomes can contain two very different chromosomes and still be considered normal?
the sex chromosomes. females are XX and males XY. the males chromosmes is where onewould find the difference
Do males and females have the same number of chromosomes in their sex cells?
Yes, male wolves have the same number of chromosomes as females. There is no research at this time on the DNA found in the X chromosome and the Y chromosome and the Wolf. The Wolf has 78 chromosomes.
What sex chromosomes are found in males?
Males have both X & Y chromosomes
How many x and y genes a female human have?
Normal biological females have two x chromosomes and zero y chromosomes; while males have one of each
What are the sex chromosomes in men and women?
X and Y are the human sex chromosomes. Normal females have XX, normal males have XY. In humans, it is the presence of a Y chromosome that makes a person male, not the ratio to or number of X chromosomes. (Therefore a person with XXY would be male).
Why do males produce two different gametes with respect to sex chromosomes?
Males have two different sex chromosomes, X and Y. Each sperm only carries half the amount of chromosomes of normal (non-sex) cells. This is so that when sperm and egg combine, the new organism has the correct number of chromosomes, half from each parent. So each sperm will carry 22 autosomes (non-sex chromosomes) and either an X or Y chromosome - because this is half the male's genetic information.
Name one pair of chromosomes not homologous in a normal karyotype?
The X (female) and Y (male) chromosomes. A person with XX is female. A person with XY is male.
Contrast the sex chromosomes found in human females and human males?
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.
What are gametes and which ones are produced by males?
gametes are sex cells that have haploid number of chromosomes. Sperm are the ones produced by males, or pollen in plants.
How many total sex chromosomes are found in normal human cells?
Two. X and Y in males. Two Xs in females.
