What is relationship between gametes and genetic variation?

Gametes are specialized cells involved in sexual reproduction that carry genetic information. Through the process of meiosis, gametes undergo genetic recombination, resulting in new combinations of genes and increasing genetic variation in offspring. This genetic variation is essential for the diversity and adaptability of species.


What To maintain the chromosome number of an organism the gametes must?

Be produced by meosis.


What chromosome is the sex determining chromosome?

That would be the chromosome number 23. Regarding the [sex] chromosome number 23, the female gametes always have a [haploid] X chromatid, whereas the male gametes are just as likely to possess a [haploid] X chromatid as they are to possess a [haploid] Y chromatid.


Is it true that meiosis and the joining of gametes generate genetic variation in offspring?

true


A specie with a diploid chromosome number of 4 if gametes were formed by mitosis rather than meiosis what would happen to the chromosome number of the offspring of these organisms over generations?

If gametes were formed by mitosis instead of meiosis in a species with a diploid chromosome number of 4, the chromosome number of the offspring would remain constant from generation to generation. Mitosis produces daughter cells with the same number of chromosomes as the parent cell, so the offspring would continue to have 4 chromosomes per cell. This would result in no variation in chromosome number over generations.

How many possible chromosome combinations are there for the gametes of an organism with a haploid number equal to 4?

2^n possible combinations


What effect does nondisjunction have on the chromosome number of the gametes?

It gives one of the gametes an extra chromosome and leaves the other gamete with one less chromosome.


Name the 2 human gametes and tell their chromosome number?

The human gametes are Male gametes are sperm and female gametes are eggs. And the gametes chromosome numbers are 42.


Do somatic cells or gametes have no matched chromosome pairs present?

Gametes only have one of each chromosome, whereas somatic cells have a pair.


How many chromosome are in dog gametes?

39


What are 2 possible end results of meiosis?

There could be 4 daughter cells with half the chromosomes as the original. Another outcome is crossing over in which one allele from one chromosome changes positions with an allele from another chromosome.


Why does meiosis exist?

Meiosis exists to ensure genetic diversity and reduce chromosome number in gametes, helping to maintain the correct chromosome number in the offspring. It also facilitates sexual reproduction by producing haploid gametes that combine to create genetically unique offspring.

How does nondisjunction during meiosis I and II affect the distribution of chromosomes in gametes?

Nondisjunction during meiosis I and II can lead to an unequal distribution of chromosomes in gametes. This can result in gametes having an extra chromosome (trisomy) or missing a chromosome (monosomy), which can lead to genetic disorders in offspring.


Does sperm contain x and y chromosome?

In humans the male sperm contains EITHER an X chromosome, or a Y chromosome since human gametes are haploid (n) in chromosome number.


How are the gametes produced by meiosis alike?

Gametes produced by meiosis have half the number of chromosomes as the parent cell. They each undergo two rounds of cell division in meiosis to reduce the chromosome number and create genetically diverse gametes. Additionally, meiosis involves crossing over and random assortment of chromosomes, contributing to genetic variation in gametes.
