The presence of both X and Y chromosomes in the inheritance pattern adds diversity, allowing for the expression of various traits associated with these chromosomes. This diversity is particularly evident in determining the biological sex of offspring, where the combination ...

Half of the children are boys, and the other half are girls because the father can contribute either an X or a Y chromosome. The combination of the X received from the mother and either the X or Y from ...

The sex of offspring is determined by the inheritance of sex chromosomes from the parents. All children inherit an X chromosome from their mother. If a child inherits an X chromosome from the father, they will be a girl, and ...

Women have a homologous pair of X sex chromosomes (XX), while men have a mismatched pair consisting of one normal-sized X and a short Y chromosome (XY).

Unlike most human chromosomes, which are paired with a maternal and a paternal copy, the sex chromosomes do not always form a perfect pair. Humans have 22 pairs of autosomes, but the sex chromosomes, X and Y, do not always ...

Although individuals inherit similar gene sets from both parents, it is the combination of these genes, particularly those on the sex chromosomes, that determines sex. In humans, the presence of either XX (female) or XY (male) sex chromosomes inherited from ...

In human beings, the sex of an individual is predominantly genetically determined. The genes inherited from parents play a key role in deciding whether the individual will be male or female.

In certain reptiles, such as some turtles, the temperature at which fertilized eggs are kept determines the sex of the developing animals. This environmental cue influences whether the offspring will be male or female.
