Who is responsible for sex determination in humans the male or the female parent?
The sex determination in humans is determined by the male parent through the presence of the X or Y chromosome in the sperm. The female parent always contributes an X chromosome. If the sperm carries an X chromosome, the resulting offspring will be female (XX), and if it carries a Y chromosome, the offspring will be male (XY).
Which chromosmoes contains sex-linled genes?
Sex-linked genes are located on the sex chromosomes, particularly on the X and Y chromosomes. On the X chromosome, X-linked genes are inherited differently between males and females, while the Y chromosome carries genes related to male sex determination and fertility.
Why does the father ultimately determine thesex if the baby?
The father's contribution to the baby's sex determination is through the sperm, which carries either an X (female) or Y (male) chromosome. The mother's egg always carries an X chromosome. When a sperm carrying a Y chromosome fertilizes the egg, the baby will be male; when a sperm carrying an X chromosome fertilizes the egg, the baby will be female.
Are all sex-linked traits located on the X chromosome?
No, not all sex-linked traits are located on the X chromosome. Some sex-linked traits can also be located on the Y chromosome.
If a characteristic is sex-linked then where is the gene for it found?
Genes for sex-linked traits can be found on the sex chromosomes - X and Y. Almost all sex-linked traits are determined by the X chromosome, because it is much larger than the Y chromosome and can thus carry more genes. A few sex-linked traits are known on the Y chromosome, including - believe it or not - hairy ears.
What is the female chromosome?
The X chromosome is one of the two sex-determiningchromosomes in many animal species, including mammals (the other is the Y chromosome). It is a part of the XY sex-determination system and X0 sex-determination system. The X chromosome was named for its unique properties by early researchers, and this resulted in its counterpart being named the Y chromosome for the next letter in the alphabet when it was discovered later.
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.
Chromosome that plays the largest role in human sex determination is?
The chromosome that plays the largest role in human sex determination is the X and Y chromosomes. In males, the presence of a Y chromosome leads to the development of male characteristics, while in females, two X chromosomes are present.
How is x chromosome involved with sex determination?
In humans, normal females have XX chromosomes, and males have XY. It is the presence of a Y chromosome that makes an individual a male, not the ratio of X to Y or the presence of only one X. Therefore someone with XXY would be male.
Who is responsible for sex determination in humans the male or the female parent?
The sex determination in humans is determined by the male parent through the presence of the X or Y chromosome in the sperm. The female parent always contributes an X chromosome. If the sperm carries an X chromosome, the resulting offspring will be female (XX), and if it carries a Y chromosome, the offspring will be male (XY).
Sex determination in the unborn baby?
Sex determination in an unborn baby is determined by the combination of sex chromosomes inherited from the parents. Typically, females have two X chromosomes (XX) and males have one X and one Y chromosome (XY). During fertilization, the father's sperm can contribute either an X or a Y chromosome, determining the genetic sex of the offspring. This process occurs at the moment of conception and is responsible for the development of the baby's sex characteristics.
How is the sex determination of kittens determined?
The sex determination of kittens is determined by their chromosomes. Female kittens have two X chromosomes (XX) and male kittens have one X and one Y chromosome (XY).
What does an x and y chromosome identify?
In the cytological terminology x and y chromosomes are identified as sex chromosomes. In human being these chromosomes are responsible for determination of sex in the offspring.
What is X chromosome?
The x chromosome is one of the sex chromosomes, the other being the y chromosome. In mammals there are two of the sex chromosomes in each organism. Females generally contain two x chromosomes, and males contain one x chromosome and one y chromosome.
How is cat sex determination determined?
Cat sex determination is determined by the presence or absence of a specific pair of sex chromosomes. Female cats have two X chromosomes (XX), while male cats have one X and one Y chromosome (XY). The combination of these chromosomes determines the sex of the cat.
Which chromosmoes contains sex-linled genes?
Sex-linked genes are located on the sex chromosomes, particularly on the X and Y chromosomes. On the X chromosome, X-linked genes are inherited differently between males and females, while the Y chromosome carries genes related to male sex determination and fertility.
What is the link between sex-linked disorders and sex chromosome disorders?
sex-linked is normally involving X chromosome sex chromosome normally involving Y chromosome
