What is the number of chromosomes in the zygote if the parent's reproductive cells or gametes contain 12 chromosomes each?
It will be 24 in the zygote since zygote is diploid cell and gametes are haploid.
If a cell has 14 chromosomes and undergoes meiosis how many chromosomes will each cell have?
The daughter cells will have 14 chromosomes, the same as the parent cell. Not only are the numbers of chromosomes the same, but they are also genetically identical to each other and the parent cell.
What is true about any two normal gametes from a human female parent?
They have the same number of chromosomes
Why do gametes have half the number of chromosomes as somatic cells?
Since you need 46 chromosomes total to function properly, and each of your parents have 46 chromosomes, you need to get 23 chromosomes from each of your parents in order to have the correct number of 46 chromosomes. You get 22 somatic chromosomes (autosomes) and 1 sex chromosome from each parent. Of course, during oogenesis or spermatogenesis, there could be nondisjunction, resulting in you receiving more or less chromosomes than you should. An example of this is Down Syndrome, where you receive an extra copy of Chromosome 21 from either parent. However, generally you will only receive 23 chromosomes from each parent (through their gametes) so that when they combine, you will have the correct 46 chromosomes. That is why gametes (haploid) have half the number of chromosomes as somatic cells (diploid).
What is gamete fusion?
It is the process during the formation of a zygote when two gametes, each carrying a different set of chromosomes, fuse together. This ensures that the developing zygote has a set of chromosomes from each parent and the cells can divide properly.The fusion of gametes is called sexual reproduction. There must be two gametes present for sexual reproduction to occur and they must have to correct number of chromosomes.
Where do zygotes get chromosomes from?
A zygote is produced by the merger of two gametes, which are an ovum and a sperm. The gametes are produced by the two parent organisms. That's where the chromosomes come from. This process is known as heredity.

It will be 24 in the zygote since zygote is diploid cell and gametes are haploid.

How many chromosomes in rafflesia?
the number of chromosomes present in the somatic cells of rafflesia flower is 12... but as in gametes,gametes are formed by meiosis or reductional division ( in which the number of chromosomes becomes half the parent cell so that after fertilization, the original chromosome count is restored and the organism is identical), the number of chromosomes found in the games of raffleisa will be 12/2 or 6 chromosomes.
How many chromosomes do horses have in their parent cells?
A horse has 64 chromosomes arranged as 32 pairs.
How many chromosomes does a gamete cell have?
75
How many chromosomes in meiosis?
The original question was not asking about "each new cell," but rather they were asking about the parent cell which is the start of meiosis. The answer is, each parent cell, NOT gamete cell, contains 46 chromosomes or is diploid, (2n). After the two divisions that occur in meiosis, the end result will be four haploid (n) cells or rather, four cells with 23 chromosomes each.
How does the number of chromosomes in gametes of an organism that reproduces sexually differ from the numbers of chromosomes in other cells?
Unlike somatic (body) cells, gametes have two time the number of chromosomes as body cells. Gametes (2n). Body cells (n). For example, human 46 chromosomes in gamete cells but half of that (23) in body cells.
Hypothesize why you may not look exactly look like a brother or a sister if you have the same parents?
This is because every person gets a set of chromosomes from one parent, and another set from another parent. That parent also got their chromosomes, one from each parent. Every human cell has 46 chromosomes, with the exception of gametes (sex cells). During meiosis, the 46 chromosomes replicate to 92. In prophase of meiosis I, crossing over occurs, when the homologous chromosomes exchange genetic material to create a recombinant. Furthermore, during metaphase I, there is independent assortment: the chromosomes from the parent A and parent B can be in any arrangement. When anaphase I occurs, the homologous chromosomes are pulled apart. The two cells will not be the same. When meiosis II takes place, the result is 4 gametes, each containing different genes due to crossing over and independent assortment. This happens in both parents. Therefore, when parent A and parent B have a second child, it is impossible for the second child to look exactly the same as the first child.
