If crossing over didn't happen during meiosis in humans, the haploid daughter cells would all have the same genes. The crossing over creates variation and causes each daughter cell to have slightly different genes.

Is it true crossing over decreases the genetic variability in humans?
yes, generally it does but does he opposite in animals
What are the differences between human fruit fly and pea plant genetic?
the procces of meiosis happends the same way in humans as in fruit flies.
How does crossing over explain genetic variability?
Normally the genes on a chromosome are inherited as a complete set. If you get that chromosome you get all the genes on it. In the process of crossing over similar sections of DNA are swapped from one chromosome to another. This means that different pairings of genes will be inherited together going forward.
Which would most likely decrease the genetic variation in the human population?
If the human population was reduced to a very small number of interbreeding individual then this small population, denied outbreeding, would have very little genetic variation. Humans, who went through a bottleneck event about 70,000 years ago, are considered a " small " species because they have little genetic variation in comparison to many other species. Google cheetah to see how this concept works.
Are men slaves to science and technology?
no men are not slaves of science and technology we cant just look past it because we are used to having it. If you were to take all technology on earth away what would happen? nearly all humans would go crazy!
What would happen if crossing over during meiosis didn't happen in humans?
If crossing over didn't happen during meiosis in humans, the haploid daughter cells would all have the same genes. The crossing over creates variation and causes each daughter cell to have slightly different genes.
What would happen if crossing over didn't happen in meiosis in humans?
If crossing over didn't happen during meiosis in humans, the haploid daughter cells would all have the same genes. The crossing over creates variation and causes each daughter cell to have slightly different genes.
What would happen if crossing over in meiosis didn't happen in humans?
If crossing over didn't happen during meiosis in humans, the haploid daughter cells would all have the same genes. The crossing over creates variation and causes each daughter cell to have slightly different genes.
What causes genetic variations in humans?
meiosis... for example.. crossing over
What would be the result if crossing over didnt happen during meiosisin humans?
There would be less genetic variation in humans
Is crossing over a chromosomal abnormality?
No, crossing over is a normal genetic process that occurs during meiosis when homologous chromosomes exchange genetic material. Chromosomal abnormalities are structural or numerical changes to the chromosomes that can result in genetic disorders.
Which is responsible for most genotypic and phenotypic variation among humans 1 meiosis 2 budding 3 mitosis or 4 regeneration?
Meiosis is responsible for most genotypic and phenotypic variation among humans because it produces haploid gametes with unique combinations of parental genes through crossing over and independent assortment during prophase I.
When do organisms complete meiosis?
Organisms complete meiosis during the formation of gametes, which are specialized cells involved in sexual reproduction. In humans, meiosis occurs during the formation of eggs in females and sperm in males.
When do humans need meiosis?
Meiosis produce haploid cells.So meiosis is used to produce sperms and ova.
How many cells does meiosios produce and are they genetically identical?
Meiosis produces four daughter cells, each with half the number of chromosomes as the parent cell. These daughter cells are not genetically identical due to crossing over and random assortment of chromosomes during meiosis I.
What is the number of chromosomes in daughter cells in humans during meiosis?
Meiosis produces daughter cells with half as many chromosomes as the parent cell. This means that because a normal human cell has 46 chromosomes, a gamete (produced through meiosis) will only contain 23 chromosomes.
When does meiosis occur?
Meiosis typically occurs during the formation of reproductive cells (eggs and sperm) in organisms for sexual reproduction. In humans, meiosis happens during the formation of eggs (in females) and sperm (in males) during gametogenesis.
