∙ 11y agoIf 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.
Why are robots used instead of humans?
they do a better job then humans they can work longer then humans and do the same thing over and over again

What would be the result if crossing over didnt happen during meiosisin humans?
There would be less genetic variation in humans
What causes genetic variations in humans?
meiosis... for example.. crossing over
When do humans need meiosis?
Meiosis produce haploid cells.So meiosis is used to produce sperms and ova.
Which is responsible for most genotypic and phenotypic variation among humans 1 meiosis 2 budding 3 mitosis or 4 regeneration?
Budding , mitosis and regeneration have no link with genetic variation.All variations in human being and other organisms are produced by MEIOSIS. During meiosis following important processes take place which include 1; crossing over in Prophase I ; Independent assortment of chromosomes and genes during Metaphase I , both of them result in reshufling of genes which is base of variation. Another source of variation is MUTATION.
What process in humans produces gametes?
Meiosis
How do mitosis and meiosis differ among humans chickens and alligators?
Meiosis differ among humans and alligators because the number of chromosomes that is given from the parents.
What reproduction is meiosis an important step for?
Meiosis is important for the production of gametes (sperm and eggs) in humans.
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.
How many chromosomes are present when meiosis starts?
In humans, 46 chromosomes are present when meiosis begins. The four daughter cells that result from meiosis have 23 chromosomes.
