When somatic cells reproduce by mitosis does crossing over take place?
Yes. However, crossing over occurs much less frequently in somatic cells than in meiotic cells. Evidence of mitotic crossing over is the occurence of twin spots in Drosophila and other organisms.
What is the process in which DNA changes to form new alleles?
Crossing-over
What is homologous chromosomes frequently exchange portions of their DNA called?
It's called crossing over, and it generally only happens between homologous chromosomes.
What does crossing over ensure?
Crossing over ensures that there is another side.
What is the product of crossing over called?
Recombinant DNA is the product of crossing over.
When somatic cells reproduce by mitosis does crossing over take place?
Yes. However, crossing over occurs much less frequently in somatic cells than in meiotic cells. Evidence of mitotic crossing over is the occurence of twin spots in Drosophila and other organisms.
Does crossing over occur during prophase 1?
Yes, only prophase 1 of meiosis. Crossing over occurs when homologous pairs of chromosomes (tetrads) line up in prophase I. In prophase II there are no tetrads left, only sister chromatids, so there is nothing there to recombine with.
What is it called when genes swap during meiosis?
This is the process of crossing over that happens in prophase I.
New genetic combinations result from?
crossing over. sexual reproduction. mutations.
What is the process in which DNA changes to form new alleles?
Crossing-over
Does recombination only occur through single crossing over events?
Yes
How can crossing over result in gene duplication?
No, only switches traits inside the crossed over segments
What is homologous chromosomes frequently exchange portions of their DNA called?
It's called crossing over, and it generally only happens between homologous chromosomes.
What does crossing over mean?
Crossing Over Means Going To Heaven Which means Crossing over from the world to heaven i think that is what it means.
What does crossing over ensure?
Crossing over ensures that there is another side.
How does crossing over incrase phenotypicvariation in a population?
crossing over allows new genes to be made by the crossing over itself or by mutations that occur in the genes as crossing over occurs. since the phenotype is the physical appearance of the gene, the crossing over can change the genotype which can change the phenotype.
What is a process in which homologous chromosomes exchange portions of their chromatids during meiosis?
the process in which homologous chromosomes exchange portions of their chromatids during meiosis is the definition of the term "Crossing Over"
