X
Both sexes have an X chromosome. Females have 2 X's and males have a X and a Y. Males, therefore determine sex.
X
What differentiates a male from a female based off the chromosomes that are present is that a male organism will have X and Y chromosomes whereas a female organism will have X and X chromosomes.
Y chromosome is autosomal dominant chromosome. When it is present, the sex of the child is male. When both the chromosomes are X, then the sex of the child is female. X chomosome is called as autosomal recessive chromosome.
23 chromosome pairs in BOTH male and female.
In humans, which sex chromosome determines if an offspring is a male or female?
The human male has both an X and Y chromosome which determines the sex of an offspring. Female only have the X chromosome.
What differentiates a male from a female based off the chromosomes that are present is that a male organism will have X and Y chromosomes whereas a female organism will have X and X chromosomes.
TDF (testicular determining factor) is a gene found on the Y chromosome that will determine if one is male or female. If it is present, one is a male. If it is absent, one is a female.
Y chromosome is autosomal dominant chromosome. When it is present, the sex of the child is male. When both the chromosomes are X, then the sex of the child is female. X chomosome is called as autosomal recessive chromosome.
23 chromosome pairs in BOTH male and female.
In humans, which sex chromosome determines if an offspring is a male or female?
The Y chromosome is the male sex chromosome, but males also carry a X chromosome from their mother. XY. The female sex chromosome is the Y chromosome; YY is female. ( generally, as sex chromosome number in both sexes can vary )
In humans, which sex chromosome determines if an offspring is a male or female?
It is on the X Chromosome (male have XY chromosome Females have XX Chromosome)
One of the two types of sex chromosomes, present twice in female cells and once in male cells.
The human male has both an X and Y chromosome which determines the sex of an offspring. Female only have the X chromosome.
If it has a x and y chromosome it is from a male if it has two x chromosome or is from a female
The reason the chance of a zygote being a male of female is the same is due to simple genetics. Females only possess the X chromosome while males posses both an X chromosome and a Y chromosome. Since females only have an X chromosome they can only "give" an X chromosome while a male may give either an X or Y chromosome.
