How does process of crossing over increase the diversity within a sexually reproducing species?

in crossing over the gens present on chromosomes forms linkage so the character are exchange & thus it lead to recombination of genes that affect genetic diversity

What will the genetic material of a organism do when it produces sexually?
The genetic material of a sexually reproducing organism evolves for better adaptations.
What does ac dc mean sexually?
Both straight and gay sexually. Bisexual.
Which phrase does not describe cells cloned from a carrot?
They are produced sexually.
Why can the number of bacteria increase rapidly in a short period of time?
Most of bacterias if not all are single celled organism, they can produce sexually or asexually (cloning). However most does tend to clone itself, this speeds up the reproductive cycle which allows them to multiply quickly.
What happens after meiosis to introduce even more genetic variation in sexually reproduced organisms?
fusion of gametes via fertilization
Why is its advantageous for a redwood to reproduce sexually when it could reproduce asexually instead?
It increases the genetic diversity of the tree's offspring.
What is an important factor in increasing variety among sexually reproducing organisms?
Because male and female cross the age of 18 they are reproducing are sex
What constantly provides new variation for natural selection to act upon in a sexually reproducing popularion?
Firstly, mutation. In a sexually reproducing population recombination ( independent orientation of chromosomes and crossing over in meiosis and random fertilization ) is also a source of variation in populations.
Does asexual reproduction incress or decress diversity?
Decreases diversity because asexual reproduction is almost a cloning process and the progenitor organism transmits 100% of it's genetic endowment to it's off spring while sexually reproducing organisms contribute 50% each in genetic material and, with independent assortment, crossing over a random fertilization, sexually reproducing organisms posses much more genetic diversity that asexual reproducers. In fact some biologists think that when more complex organisms go this route that they are headed for extinction. Less complex asexual reproducers have a high mutation rate and have mechanisms for exchanging genetic material laterally.
Why does a sexually-reproducing species have an advantage over asexually-reproducing species?
Sexually-reproducing species have an advantage over asexually-reproducing species in their ability to use two different sex cells.
Sexually-reproducing species have an advantage over asexually-reproducing species in there ability to?
Sexually-reproducing species are able to adapt more easily than asexual-reproduciing species
Sexually-reproducing species have an advantage over asexually-reproducing species in their ability to?
adapt
What is the process of plants reproducing sexually?
they multiply
If meiosis did not occur in sexually reproducing organisms?
If meiosis did not occur in sexually reproducing organisms, the chromosome number would double in each generation. Sexual reproduction results in new combinations of genetic traits.
How does fungi reproduction occurs?
by reproducing asexuallly or sexually
Where do sexually reproducing organisms inherit their alleles from?
From their parents.
In sexually reproducing organisms, genes are transferred via _______________?
The gametes.
