There are two types of chromosome, called X and Y.
Semen contains X sperm and Y sperm.
If the Y sperm fertilises the female ovum, the child will be male.
If the X sperm fertilises the female ovum, the child will be female.
A man's chromosomes will be XY and a woman's chromosomes will be XX. The man's sperm always determines the gender of the baby.
What else can I help you with?
What kind of egg does a female produce?
the female gamete, the egg or ovum
What Kind of cells can mitosis not make?
Mitosis can't produce gametes as sperms and ova, which have 23 chromosomes. It only produces somatic cells which are used in the rest of the body that contain 46 chromosomes.
What kind of chromosomes do females transmit to offspring?
Female transmit 23 chromosomes to the offspring. She has that unique chromosome called as X chromosome. This is transmitted to the offspring. From male you get either X or Y chromosome. From XX chromosome you get female child. From XY chromosome you get male child.
Can two animals have a different kind of animal?
Yes they can,a horse and a donkey produce a MULE also a male tiger and a female lion produce a TIGON, on the reverse a male lion and a female tiger produce a LIGER, and both are recognised species of animal.
What kind of chromosomes do the body cells of humans have?
All Human Body Cells, also called somatic cells, have 46 chromosomes. These 46 occur is 23 pair. The first 22 pair are called autosomes. The 23rd pair are the sex chromosomes, xx for female, xy for male.
When DNA is combined from two different sources what kind of organism does it produce?
If the two different sources of DNA are a sperm and egg cell, they produce a diploid organism, which means that it has two sets of chromosomes in its body cells.
Why is it necessary to have a haploid cell at the end of meiosis?
In most plants and animals, each cell has two copies of each chromosome. Cells having 2 of each kind of chromosome are called diploid. For instance, human cells have 46 chromosomes (23 different kinds of chromosomes, and 2 copies of each kind). They are diploid. Now think about what happens when a sperm fertilizes an egg. If a sperm has 46 chromosomes, and an egg has 46 chromosomes, then you might think that the fertilized egg would have 92 chromosomes since it is formed by putting together the sperm and the egg. But this doesn't happen. Why not?Sperm cells and egg cells are produced by a process of cell division called meiosis that cuts the number of chromosomes in half (each sperm cell has 23 chromosomes and each egg cell has 23 chromosomes). Then when the sperm and egg combine during fertilization, they produce a cell that has the normal number of chromosomes again. (23 + 23 = 46). Meiosis reduces the number of chromosomes by putting one of each kind instead of two of each kind in each sperm and in each egg. Cells that have only one copy of each kind of chromosome are called haploid. Sperm cells and egg cells are haploid. All other cells in the body have two of each kind of chromosome and are called diploid.
What kind of chromosome do females transmit of offspring?
Female transmit 23 chromosomes to the offspring. She has that unique chromosome called as X chromosome. This is transmitted to the offspring. From male you get either X or Y chromosome. From XX chromosome you get female child. From XY chromosome you get male child.
Why might this kind of reproduction be easier than having only male cells or female cells?
pollenation is necessary for reproduction
Gametes have what kind of Chromosomes?
Gametes have haploid chromosomes, which means they have half the number of chromosomes of other cells in the body.
What kind of protein does mosquitoes needs to develop their eggs?
Female mosquitoes need a blood meal to obtain the protein necessary for developing their eggs. This blood meal provides essential nutrients, including proteins and lipids, that are used to produce eggs. Without a blood meal, female mosquitoes are unable to reproduce effectively.
What kind of cells has chromosomes?
all
