If two fraternal twins have the XY sex chromosomes, they will be male.
No, XY combination of chromosomes produces a male baby. To produce a female baby, the combination of chromosomes must be XX. The mother's egg is always X, so the deciding vote goes to the father's sperm to choose an X or a Y chromosome - to see whether we'll be a boy, or a girl.
xy chromosomes mostly fall on male gender.
Sex chromosomes determine an individual's biological sex. Typically, females have two X chromosomes (XX) and males have one X and one Y chromosome (XY). A combination of XX would result in a female, while XY would result in a male.
the genotype for a male is XY thank you, Allyson
XX for a girl and XY for a boy
The two letters that express a male chromosomes combination is XY.
XY
XY
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 combination of sex chromosomes is shown in the image: XY (APEX)
Xy=male xx=female
Y chomozomes, I think. It says on Wikipedia.
About half of us DO have an XY chromosome. Males. XX chromosomes are female.
46 chromosomes or 23 pairs of chromosomes where 44+xx or 44+xy xx are girls xy are boys
XY chromosomes SDT
No, XY combination of chromosomes produces a male baby. To produce a female baby, the combination of chromosomes must be XX. The mother's egg is always X, so the deciding vote goes to the father's sperm to choose an X or a Y chromosome - to see whether we'll be a boy, or a girl.
XY Chromosomes = Males XX Chromosomes = Females
