The sex of an offspring is primarily determined by the combination of sex chromosomes inherited from the parents. In humans, females typically have two X chromosomes (XX), while males have one X and one Y chromosome (XY). The sperm cell from the male parent can carry either an X or a Y chromosome, which, when combined with the X chromosome from the female parent, determines the sex of the offspring. If the sperm carries an X chromosome, the offspring will be female (XX); if it carries a Y chromosome, the offspring will be male (XY).
What else can I help you with?
Is the sex of the offspring is determined by the female parents chromosomes?
No. it is determined by the male parent's chromosomes.
Is the sex of the offspring determined by the female parents chromosomes?
No, the sex of the offspring is determined by the combination of chromosomes from both parents. In mammals, females have two X chromosomes (XX) while males have one X and one Y chromosome (XY). The sex of the offspring is determined by whether the father contributes an X or Y chromosome during fertilization.
The sex of offspring is determined by the chromosome the female parent gives true or false?
True. The sex of offspring is determined by the sex chromosome contributed by the female parent. Females have two X chromosomes, while males have one X and one Y chromosome.
Is the sex offspring is determined by the chromosome the female parent gives?
Yes, the sex of the offspring is determined by the chromosomes contributed by the parents. The female parent always gives an X chromosome, while the male parent can contribute either an X or a Y chromosome, determining whether the offspring will be male (XY) or female (XX).
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.
Can a female kangaroo determine the sex of its offspring?
No, a female kangaroo cannot determine the sex of its offspring before giving birth. The sex of the joey is determined by the chromosomes contributed by the male kangaroo during fertilization. However, once the joey is born, the mother can influence its development through factors like nutrition and environmental conditions, but she does not have control over the sex of the offspring.
What scientist discovered that sex chromosomes differ in size?
Nettie Stevens discovered that sex chromosomes differ in size in 1905. She observed that the sex chromosomes in mealworms determined the sex of the offspring.
What determines the sex of offspring in humans and why is it important in the process of reproduction?
The sex of offspring 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). This is important in the process of reproduction because it determines the biological characteristics and reproductive capabilities of the offspring.
Is the sex of a human offspring determined by the mother fathe r or neither?
Technically, the sex is determined by the father. The egg is always an x chromosome. The sperm can be either an x or a y chromosome. An xx makes a female, and an xy makes a male.
The sex of a child is determined by?
In humans the sex of the offspring is determined by which sperm is able to fertilize the ovum. If a sperm containing the X chromosome fertilizes the ovum, a female offspring results. If a sperm containing the Y chromosome fertilizes the ovum, a male offspring results
Why does the sperm determine the sex of the offspring not the egg?
The sex of offspring is determined by the sperm because sperm carries either an X or Y chromosome, while eggs always carry an X chromosome. If a sperm carrying an X chromosome fertilizes the egg, it results in a female offspring (XX), while a sperm carrying a Y chromosome leads to a male offspring (XY).
Is the sex of the offspring of a cow determined by the egg or sperm?
The sex of the offspring is always determined by the sperm: this is the same in pretty well all animal life, including human reproduction. The gamete in a cow always carries the X chromosome. The gametes in a bull carry both X and Y chromosomes, which mean that if the sperm with an X chromosome fuses with the gamete of the cow, the offspring will be female. If the sperm carries a Y chromosome and fuses to the female gamete of the cow, then the offspring will be male.
