An X and a Y would indicate a male.
And just in case you were wondering; an X and X would indicate a female.
In humans and other mammals, a male has XY sex chromosomes. In birds, a male has XX chromosomes. In amphibians, male chromosomes look the same as female chromosomes.
A male formula is commonly referred to as "male" in the context of biological sex determination. In genetics, particularly in the context of sex chromosomes, the male formula is represented as XY, where "X" and "Y" indicate the specific sex chromosomes that typically characterize males in many species, including humans.
A karyotype can be determined to be male or female based on the presence of the sex chromosomes. In females, the karyotype typically shows two X chromosomes (46,XX), while in males it typically shows one X and one Y chromosome (46,XY).
We call these sex chromosomes. Whether you are a male or female depends on the presence or absence of certain chromosomes. The sex chromosomes are the X chromosome and the Y chromosome. If you have two XX, you will show female characteristics and If you have XY you will show male characteristics.
XY chromosomes SDT
Male sex chromosomes are the X and Y chromosomes. The presence of a Y chromosome typically determines male biological sex, while the absence of a Y chromosome typically results in female biological sex. The combination of sex chromosomes inherited from parents determines an individual's biological sex.
The sex chromosomes for a male are XY. The presence of a Y chromosome determines male biological sex, while the absence of a Y chromosome results in female biological sex.
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.
XY Chromosomes = Males XX Chromosomes = Females
The biological sex of an individual with XY sex chromosomes in humans is typically male.
Xy chromosomes= boy xx chromosomes= female
There are two sex chromosomes, X and Y. A female has XX and a male has XY.
