Does crossing over affect one or many genes?
Crossing over can effect on more then one gene i.e. at least two as in crossing over the genes of homologus chromatin get interchanged so it effect at least two genes and can effect or change more then two genes depend upon the linking and crossing over capability
What is it called when genes swap during meiosis?
This is the process of crossing over that happens in prophase I.
Compare any differences in the appearance of genes on chromosomes in gamete cells when crossing over occurs and when it does not occur?
The genes are different because crossing over causes some of the genes on the homologous pair to shuffle, creating variation.
What is propahse?
It actally spelt prophase...1. The first stage of mitosis, during which the chromosomes condense and become visible, the nuclear membrane breaks down, and the spindle apparatus forms at opposite poles of the cell.2. The first stage of meiosis, constituted by a series of events that include the thickening and coiling of the chromosomes, synapsis of homologous chromosomes, tetrad formation, and crossing over.
New genetic combinations result from?
crossing over. sexual reproduction. mutations.
Which correctly describes the effect crossing over during meiosis?
It causes the cell to split into four haploid cells.
Which correctly describes the effect of crossing over during meiosis?
It causes the cell to split into four haploid cells.
When new cells are produced how will crossing over affect how they appear?
I KNOW When new cells are produced, how will "crossing over" affect how they appear?
Does crossing over affect one or many genes?
Crossing over can effect on more then one gene i.e. at least two as in crossing over the genes of homologus chromatin get interchanged so it effect at least two genes and can effect or change more then two genes depend upon the linking and crossing over capability
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 it called when genes swap during meiosis?
This is the process of crossing over that happens in prophase I.
What does crossing-over produce in the offspring?
Crossing over in a species creates a whole new species
Are daughter cells identical to the parent cells?
exactly like parent....in mitosis different in meiosis due to crossing over in interphase I
Crossing-over can occur during the meiotic divisions that produce cells called?
Prophase I of Meiosis I .
Why are two sperm cells never identical?
No two sperm cells are identical because of the process of crossing over that occurs in prophase I of meiosis.
How do cells at the beginning of meosis compare to the cells at the end of meiosis?
There's no spindle fibers at the end of meiosis and the beggining of the meiosis is crossing over.
Does crossing over occurs in mitosis?
No, most cells undergo mitosis, and if they crossed over, like haploid cells do, we as humas would be very deformed because no cells would have the same genes and such
