What structures carry genes to the offspring?
According to the chromosome theory of inheritance, genes are carried from parent to their offspring on chromosomes.
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).
What kind of charomosome do females transmit to offspring?
Females transmit an X chromosome to their offspring, as they carry two X chromosomes (XX). Males contribute either an X or a Y chromosome, determining the sex of the offspring (XX for female, XY for male).
How can the sex of an offspring be determined?
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).
How many chromosomes dose each parent pass to their offspring?
When a parent is going to have an offspring the offspring only gets half a chromosome from each parent, they combine to make one chromosome then that chromosome gets copied until there are 23 pairs of chromosome's. This is how you get your features.
Which gamete determines the gender of the young?
In humans females are homogametic and males are heterogametic. It is the male biological parent who contributes the sex chromosome that determines the sex of any child.Human females are XX and all their ova carry an X chromosome. Females always give their children an X chromosome.Human males are XY and half their spermatozoa carry an X chromosome and half carry a Y chromosome. Depending on the sex chromosome in its biological father's spermatozoon, a child receives an X or a Y chromosome from its biological father.If a child receives an X chromosome from its father she will be XX and a girl. If a child receives a Y chromosome from its father he will be XY and a boy.
Which gamete has the chromosome that determines a person's sex?
The sperm gamete carries either an X or a Y chromosome, which determines the sex of the offspring. If the sperm carries an X chromosome, the offspring will be female, while if it carries a Y chromosome, the offspring will be male.
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.
What are the x and y chromazones?
The Y chromosome is the male sex chromosome, but males also carry a X chromosome from their mother. XY. The female sex chromosome is the Y chromosome; YY is female. ( generally, as sex chromosome number in both sexes can vary )
Difference between male and female sperm?
Although only males produce sperm, that does not mean that all sperm is male. There are two types of sperm: male and female. Male sperm carry the 'y' chromosome; female sperm carry the 'x' chromosome. If all sperm where male, then there would be no females born. Thus, the difference between male and female sperm is that male sperm carries the 'y' chromosome and produces male offspring and female sperm carries the 'x' chromosome and produces female offspring.
What carry genes that determine the sex of offspring?
Men do they are the carriers of the X and Y chromosome. Girls only have X chromosomes. Two X chromosomes mean it will be a girl and a X and a Y mean it will be a boy.
What is the largest to smallest bases DNA gene chromosome nucleus?
The largest structure is the nucleus, which contains all the genetic material of a cell. Within the nucleus, chromosomes are structures made of DNA that carry genes. Each chromosome consists of tightly coiled DNA, which is made up of sequences of bases (adenine, thymine, cytosine, and guanine). Therefore, the order from largest to smallest is: nucleus, chromosome, DNA, and bases.
