I don't know much about this but I do know that chromosomes are inside a cell. So the cell of the sperm is what carries the Chromosone.
About half of us DO have an XY chromosome. Males. XX chromosomes are female.
If two fraternal twins have the XY sex chromosomes, they will be male.
Two aspects of biological sex are chromosomes (XX for female, XY for male) and reproductive anatomy (ovaries and uterus for female, testes and penis for male).
46 chromosomes or 23 pairs of chromosomes where 44+xx or 44+xy xx are girls xy are boys
XY chromosomes SDT
XY Chromosomes = Males XX Chromosomes = Females
xy chromosomes mostly fall on male gender.
The biological sex of an individual with XY sex chromosomes in humans is typically male.
xy
the genotype for a male is XY thank you, Allyson
Sex chromosomes (XX = female and XY = 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.
