Why do gametes have different combinations of alleles?
Crossing over and random alignment of chromosomes
How many chromosomes in total would be in a sperm cell a grasshopper?
If it had 180 chromosomes in it's diploid stage (a normal body cell) you could expect to find 90 in its gametes.
What is the significance of the chromosome number in gametes?
Chromosome numbers in gametes are always half that of normal cell. For example human cells have 46 chromosomes but a human gamete (sex cell e.g sperm/eggs) will have half that number which in this case will be 23. The number is chromosomes is halfed in gametes so that when the sperm meets the egg and the fuse to make a zygote that you get half the genetic material from your Mother and half from you Father, meaning you are not a clone.
Why is it important that gametes have half the usual number of chromosomes?
So that the number of chromossomes of of the next generation don't change. In some living thins they do changed based on generation, such as plants, but in animals that reproduce sexually meiosis has to occur to keep the number of chromosomes of a species constant.
Do ALL cells contain forty-six chromosomes?
No gametes or sex cells each have 23 chromosomes. Meaning that a sperm would have 23 chromosomes (not pairs) and an egg would have 23 (also not pairs), which are called haploid cells. So when united, they pair and have 23 pairs of chromosomes, or 46 chromosomes.
A particular organism has 40 chromosomes in one of its muscle cells How many chromosomes would be found in one of its gametes?
20 chromosomes
What might happen inf the gametes of a species has the same number of chromosomes as the species' body cells?
in human being's normal cells 46 chromosomes are found whereas in gametes half of the chromosomes,that is;23 are found if gametes will have same no. of chromosomes as in normal cells than in offspring (46+46=92)chromosomes will be found but it can't happen
If a diploid organism has a genome consisting of twenty two chromosomes its gametes will have how many chromosomes?
Gametes have half the number of chromosomes - therefore if the diploid number is 22, the gametes would have 11 chromosomes.
If somatic cell has 30 chromosomes how many are in the gametes?
Since gametes are haploids, they would each contain haploid number of chromosomes, 15 chromosomes.
How many chromosomes would be found in the gametes that produced this monkey?
Half the number the monkey hasThe number of chromosomes depends on the species of monkey. So for which ever monkey you are talking about, the gametes that came together to form it each had half the total number the monkey has.
How many unique gametes can be produced via assortment for an organism with a diploid number of 6 chromosomes?
When a zygote is diploid it obtains two sets of chromosomes. Gametes contain one set of chromosomes. Therefore, 6 chromosomes would amount to 3 sets of gametes.
How many unique gametes can be produces via independent assortment for an organism with a diploid number of 6 chromosomes?
When a zygote is diploid it obtains two sets of chromosomes. Gametes contain one set of chromosomes. Therefore, 6 chromosomes would amount to 3 sets of gametes.
If gametes were diploid like somatic cells how many chromosomes would the zygote contain?
If gametes were diploid, that would mean the zygote would get 46 chromosomes (in humans that is) from his father and 46 chromosomes from his mother, that would add up to 92.
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.
Why it is important for gametes to have half as many chromosomes as normal body cells?
Gametes are involved in sexual reproduction. In order for the resulting cell from two gametes merging to have the correct number and arrangement of chromosomes, the gametes themselves need to each have exactly half of the chromosomes. If this fraction varied in any way, extreme defects would occur due to the highly different genes the resulting cell would have.
Process by which the number of chromosomes per cell is cut half used by organisms to produce gametes?
Meiosis takes a cell from 2N (Diploid) to N (haploid) and produces 4 daughter cells at 23 chromosomes. These are the sex gametes. A normal 2N cell would have 46 chromosomes.
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.
