What happens if the gametes aren't haploid?
The whole purpose of reducing the gamete to contain half the number of normal chromosomes is so that normal chromosome numbers can be achieved again when the gametes fuse to form a zygote. If the gamete is not halved, polyploidy results. This is a generic term to describe having more than the normal number of chromosomes.
What cells contain one half the amount of chromosomes and DNA in humans?
Gametes, or sex cells such as the sperm or ova contains half the number of chromosomes so that when they combine they have a normal and full set of chromosomes.
How are sperm formation and egg formation similar?
These are similarities between human spems and egg cells:Number of chromosomes: Normally both contain a haploid chromosome set, i.e. 23 chromosomes, as opposed to normal diploid body cells with 46 chromosomes.Both are developed in a process called meiosis from germ cells.Both are gametes or reproductive cells.
Are most animal gametes diploid or haploid?
Gametes are haploid, meaning they contain half the genetic material of normal (somatic) cells. This is so that when the two different gametes fuse (during sexual reproduction), the resulting organism will once again have the correct amount of chromosomes - half from each gamete.
How many chromosomes does the egg cell of a fruit fly have?
A zygote is formed from the union of two gametes. The number of chromosomes differs from different species, but in humans, there are 46 chromosomes. 23 from the male gamete and 23 from the female gamete.
Normal mice gametes contain 20 chromosomes. How many chromosomes do normal mice zygotes contain?
The answer is 40
How mice gametes contain 20 chromosomes. How many chromosome do normal mice zygotes contain?
Since the gametes contain one half the number, the zygote will have to have the full number of 40.
How many chromosomes are in a normal persons gametes?
23

What term is used to describe the single set of 23 chromosomes contained in the gametes?
23 pairs of chromosomes is called the diploid number.--- DNAJamiana:Genotypewhich one dang it don't put two of these answers in this
What cells contain one half the amount of chromosomes and DNA in humans?
Gametes, or sex cells such as the sperm or ova contains half the number of chromosomes so that when they combine they have a normal and full set of chromosomes.
How does the number of chromosome in a persons gametes compare with the numbers of chromosomes in the body cells?
There are half as many chromosomes in gametes than in normal body cells.
How many chromosome do normal mice zygotes contain?
40.
Are gametes haploid or diploid?
gametes are haploid (half the normal number of chromosomes)
How are sex cells different from others human cells?
Sex cells, called gametes, are different to other cells in that they contain half the number of chromosomes. So in a human sex cell, there are 23 chromosomes, whereas a normal human cell has 46 chromosomes.

How many sex chromosomes does a human have?
In an average somatic (body) cell, two. and in human gametes there is , one all chromosomes in human body is , 46 chromosomes. in normal female somatic cell is (44+XX) . in normal male somatic cell (44+XY) in normal female gametes (22+X) in normal male gametes (22+X) or (22+Y) .
