In what way is crossing over important for sexual reproduction?

It allows for a huge amount of genetic diversity. If crossing over wasn't part of reproduction (and it wasn't always), then the offspring would be identical to the parent, except for the possibility of mutation.
If there is more genetic diversity, the chances of one of the off spring having an advantageous trait goes up.

∙ 14y agowithout crossing over the same genetic material would be transferred to the next generation resulting in what may be called "twins". This would mean you would look exactly like your mom or like your dad. So the short answer would be genetic variation. For an alternative example we can look at rice. All rice looks the same. They all look the same because they produce asexually without crossing over.

New genetic combinations result from?
crossing over. sexual reproduction. mutations.
Genetic variability is the main advantage of?
Sexual reproduction
What are the sources of variation in the offspring produced by sexual reproduction?
Random assortment & crossing-over
Offspring that are the result of sexual reproduction are?
Better adapted to the environment due new genetic combinations by crossing over.
Which two factors provide the genetic basis for variation within a species?
mutations and sexual reproduction (due to random orientation of bivalents about the equatorial spindle during metaphase I and pairs of chromatids during metaphase II; fusion of male and females gametes during fertilization; and reciprocal crossing over)
New genetic combinations result from?
crossing over. sexual reproduction. mutations.
Genetic variability is the main advantage of?
Sexual reproduction
What is variation caused by?
It is caused by crossing over in sexual reproduction and random mutations in DNA.
What are the sources of variation in the offspring produced by sexual reproduction?
Random assortment & crossing-over
What do sexual reproduction mutation and crossing-over generate in a population?
genetic diversity!:) ur welcome
What results in the exchange of alleles and produces now combinations of alleles?
Crossing over during prophase I of meiosis.
What causes continuous variation in humans?
There is variation among humans because of sexual reproduction, crossing over, assortment, and mutations.
Why are genes are important in sexual reproduction?
because they keep mens sexual organs locked away to avoid over repopulation...

What is the function of meiosis.?
Form of nuclear division that divides a diploid cell into haploid cells;important in forming gametes for sexual reproduction Meiosis halves the number of chromosomes in the daughter cells. It also bring about new genetic combinations by crossing over. The haploids produced by meiosis form gametes and union of male and female gametes leads to sexual reproduction.Thus meiosis is the foundation stone of sexual reproduction.
