46 chromosomes.... but regarding to sex cells theres 23...
All humans have two copies of chromosomes 1-22.
Females have two copies of the X chromosome, whereas males only have one X chromosome (and a Y chromosome).
x chromosomes
Boys have one x chromosome and a y chromosome, whereas a girl has two x chromosomes.
because in metaphase 2 of meiosis there are 2 different cells, which means the chromosomes duplicated
the chromosomes pairs line in the center of the cell the chromosomes pairs line in the center of the cell
my college bio proffessor told me that even though chromosomes are still in the duplicated state, the chromosomes are duplicated so technically they do have "23" chromosomes but they instead have 2 sets of it. these 2 sets are the same so they dont count as a "full" set of 46 chromosomes. :) hope this helps!!
There are 46 chromosomes in a human diploid cell (22 paired autosomes, 2 sex chromosomes).
Gender is determined by chromosomes A male has an X and a Y chromosome. a female has 2 X chromosomes
46 chromosomes or 23 pairs of chromosomes where 44+xx or 44+xy xx are girls xy are boys
Boys have one x chromosome and a y chromosome, whereas a girl has two x chromosomes.
2 chromosomes
i believe its 2
Answer We label the human sex chromosomes with X's and Y's. For example. A boy's chromosomes are XY. A girls chromosomes are XX. When a child is born, they get an X from their mother, and either an X or Y from their Father, thus determining their sex.
1 pair of sex chromosomes Female pair is XX Male pair is XY
because in metaphase 2 of meiosis there are 2 different cells, which means the chromosomes duplicated
its a 50/50 since the girls chromosomes are xx and the guys chromosomes are xy the pairs which can be created are xx,xx,xy,xy for the offspring to become a male its a 2/4 chance which is 50% :)
The ones that determine our sex are, X Y, girls are X X
2 pairs of chromosomes....i.e.46 no. of chromosomes...
there are 23 pairs of chromosomes in human body............
