Sex determination in humans is primarily governed by the presence of specific sex chromosomes, with females typically having two X chromosomes (XX) and males having one X and one Y chromosome (XY). The sex of an offspring is inherited from the parents through the combination of these chromosomes during fertilization; the father's sperm can contribute either an X or a Y chromosome, while the mother's egg always contributes an X chromosome. Thus, if the sperm carries an X chromosome, the offspring will be female (XX), and if it carries a Y chromosome, the offspring will be male (XY). This genetic mechanism is a key aspect of human reproduction and inheritance.

How are fetus sex and inherited traits determined?
Fetus sex is determined by the combination of sex chromosomes inherited from the parents; typically, an XX combination results in a female and an XY combination results in a male. The father contributes either an X or a Y chromosome, while the mother always contributes an X chromosome. Inherited traits are determined by genes located on these chromosomes, with each parent passing down a set of alleles that influence various characteristics. The interaction of these alleles, along with environmental factors, ultimately shapes the traits expressed in the offspring.
How are a fetus sex and inherited traits determined?
A fetus's sex is determined by the combination of sex chromosomes inherited from the parents: typically, a female has two X chromosomes (XX), while a male has one X and one Y chromosome (XY). The sperm from the father carries either an X or a Y chromosome, which, when combined with the X chromosome from the mother, determines the sex of the fetus. Inherited traits are determined by genes, which are segments of DNA located on chromosomes. Each parent contributes one allele for each gene, influencing the offspring's traits based on dominant and recessive inheritance patterns.
What sex of offspring is determined by a chromosome pair?
The sex of offspring is determined by the combination of sex chromosomes inherited from the parents. In humans, females have two X chromosomes (XX) and males have one X and one Y chromosome (XY). The presence of a Y chromosome determines the development of male characteristics.
What is allele inherited on sex chromosomes?
Sex-linked gene
What is a physical trait determined by inherited genes?
Eye color is a physical trait that is determined by inherited genes. The specific combination of genes inherited from parents determines the color of an individual's eyes.
How is the genetic sex of a child determined?
The genetic sex of a child is determined by the combination of sex chromosomes inherited from the parents. Typically, a child with two X chromosomes is female, while a child with one X and one Y chromosome is male.
What determines the sex in humans, and how is it determined by sex chromosomes?
The sex of a human is determined by the presence of sex chromosomes. Females have two X chromosomes (XX), while males have one X and one Y chromosome (XY). The combination of sex chromosomes inherited from the parents at conception determines the biological sex of the individual.
How are fetus sex and inherited traits determined?
Fetus sex is determined by the combination of sex chromosomes inherited from the parents; typically, an XX combination results in a female and an XY combination results in a male. The father contributes either an X or a Y chromosome, while the mother always contributes an X chromosome. Inherited traits are determined by genes located on these chromosomes, with each parent passing down a set of alleles that influence various characteristics. The interaction of these alleles, along with environmental factors, ultimately shapes the traits expressed in the offspring.

How is sex determined in humans?
Sex in humans is determined by the combination of sex chromosomes inherited from the parents. Females have two X chromosomes (XX) and males have one X and one Y chromosome (XY). The presence of a Y chromosome typically leads to the development of male characteristics.
How is kitten sex determination determined?
Kitten sex determination is determined by the chromosomes inherited from the parents. Female kittens have two X chromosomes (XX) and male kittens have one X and one Y chromosome (XY). The presence of the Y chromosome determines the male sex.
How is the sex of an embryo determined?
The sex of an embryo is determined by the combination of sex chromosomes inherited from the mother and father. Typically, females have two X chromosomes (XX) and males have one X and one Y chromosome (XY). The presence of a Y chromosome triggers the development of male characteristics.
How are sex-linked traits inherited?
Sex-linked traits are inherited from the organism's parents.
How is sex determined in biological organisms?
Sex in biological organisms is determined by the combination of sex chromosomes inherited from the parents. In humans, females have two X chromosomes (XX) and males have one X and one Y chromosome (XY). The presence of the Y chromosome typically leads to the development of male characteristics.
Is the sex of a child determined by genetics or other factors?
The sex of a child is determined by genetics, specifically by the combination of sex chromosomes inherited from the parents. Typically, a child with two X chromosomes is female, while a child with one X and one Y chromosome is male. Other factors do not play a significant role in determining a child's sex.
Is human eye color a sex linked character?
No, human eye color is not a sex-linked trait. It is determined by multiple genes and is inherited in a complex manner involving both genetic and environmental factors.
What example best describes an inherited trait that can be determined by looking at a individual?
Eye color is an example of an inherited trait that can be determined by looking at an individual. The color of a person's eyes is determined by the combination of genes inherited from their parents. This trait is visible and easily observed, making it a clear example of an inherited characteristic.
