Is crossing over a chromosomal abnormality?
No, it is normal for chromosomes to cross over. Crossing over is how we humans have genetic diversity.
What is the result of crossing over?
The crossing over alleles is critical to the survival and genetic diversity of a species. The results of the random crossing over of alleles is that the offspring will have chance inheritance of certain characteristics from their parents (as opposed to being genetic clones with no diversity). The diversity of phenotypes are among the major manifestations of random crossing.
What are three ways to get genetic variation?
Independent assortment of chromosomes, crossing over and Random fetiliztion
What is the purpose of crossing over?
to school the person trying to get the ball
How does crossing over and nondisjunction contribute to variation and increase genetic diversity in a population?
Crossing over is when two homologous chromosomes switch genes. This causes them to become different. Nondisjunction is when there is an incorrect splitting of a chromosome. These two types of variation result in a different set of genes each time an egg and a sperm collide by chance,
How is genetic diversity to beneficial to a species?
Crossing over causes genetic diversity. If there was no genetic diversity in a species, the species would be prone to extinction.
How is genetic diversity beneficial a species?
Crossing over causes genetic diversity. If there was no genetic diversity in a species, the species would be prone to extinction.

How does crossing over affect the genetic diversity of a 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
Why is crossing over advantageous to species?
Crossing over provides genetic diversity, which means many different characteristics are given to individuals of a species. Therefore, if there is more diversity within that species, there is a higher likelihood of that species surviving, growing, and reproducing.
What are three ways to get genetic variation?
Independent assortment of chromosomes, crossing over and Random fetiliztion
What do sexual reproduction mutation and crossing-over generate in a population?
genetic diversity!:) ur welcome
How does the crossing over add to the genetic diversity of sexual reproducing is organ?
Crossing over does not have a sexual reproducing. Crossing over means after death your soul either goes to haeven or hell.
How does the process of fertilization act to increase genetic diversity within a population?
Random fertilization. All the eggs and sperm produced are variations due to crossing over alone, not even considering other processes. The meet and fertilization occurs randomly insuring a good mix of genetic variation. Thus, genetic diversity.
What does crossing-over produce in the offspring?
Crossing over in a species creates a whole new species
