the father
The sperm from the father can supply either an X-bearing or a Y-bearing chromosome. The egg from the mother can only supply an X-bearing chromosome. An XY combination produces a boy baby. An XX combination produces a girl baby. It might seem that the father therefore determines the sex of the baby, but some recent evidence suggests that the mother can select either an X-bearing or a Y-bearing sperm. See the Wikipedia article on "Maternal influence on sex determination."
The male sex chromosome is XY, and females are XX. The X comes from the female, and an X or a Y from the male. When they meet, that determines whether the baby will be a boy or a girl.
Male - in humans the sex is determined by the presence of a Y chromosome. In other animals sex can be determined by the ratio of sex chromosomes, or the total number of chromosomes.
the sex, color blindness (the gene is on the X chromosome), other sex linked traits.
The sex of a baby at fertilization is determined by the chromosomes the baby possesses. If these chromosomes are XY it's a boy. If they are XX, it's a girl. http://en.wikipedia.org/wiki/XY_sex-determination_system
In humans, which sex chromosome determines if an offspring is a male or female?
The sex chromosomes...XX for a female, XY for a male, with some other relatively rare variations.
I believe the father of the baby determines the sex of the baby.
For humans x or y chromosome from father
Normal male humans have the sex chromosomes XY. The presence of the Y chromosome determines sex in humans - so a person with XXY will be male.
In humans it is the Male.
The chromosome in the male's gamete determines the gender of the baby. If it is a Y chromosome, the baby will be a boy. If the chromosome is a X, the baby will be a girl.
Yes, the male determines the sex of a baby. He possesses the either X or Y chromosome. The X is a girl I believe & the Y is a boy, I'm pretty sure that that's what they stand for. I'm positive that the male determines the sex of a baby though.
