What is it called when two chromosomes exchange parts?
mutagenesis occurs
Is there a greater chance of crossing over between some pairs of alleles than between others?
Yes, some alleles are more likely to cross over during meiosis than others. The likelihood of crossing over between two alleles depends on the distance between them on the chromosome. Closer alleles have a lower chance of crossing over, while alleles located farther apart are more likely to undergo crossing over.
Is crossing over possible in multiple alleles?
Yes, crossing over can occur between multiple alleles located on the same chromosome. This can lead to the exchange of genetic material between different alleles during meiosis.
What results in the exchange of alleles and produces now combinations of alleles?
Crossing over during prophase I of meiosis.
How can new combinations of alleles be created when genes are linked?
New combinations of alleles can be created when genes are linked through a process called crossing over during meiosis. Crossing over occurs when homologous chromosomes exchange genetic material, resulting in the mixing of alleles between the two chromosomes. This process leads to the creation of new combinations of alleles and contributes to genetic variation in the population.
How does crossing-over affect the alleles on a chromatid?

Why does the frequency of the cross overs give information about the relative locations of genes?
its simple the crossing over of genes ha a location looc for a chromosomes with a different chromatid you have the location
When an area on a chromataid is exhanged with the matching area on a chromatid of its homologous chromosome?
- "crossing-over"
When chromosome pairs separate into different sex cells does the alleles genes stay together?
During meiosis exchange of chromatid takes place by crossing over among the homologous chromosomes and chromatids of two chromosomes facing each other are involved in crossing over. Thus 50% of the gametes formed have new arrangement of alleles and rest 50% remain like those of parent cells.
Is there a greater chance of crossing over between some pairs of alleles than between others?
Yes, some alleles are more likely to cross over during meiosis than others. The likelihood of crossing over between two alleles depends on the distance between them on the chromosome. Closer alleles have a lower chance of crossing over, while alleles located farther apart are more likely to undergo crossing over.
Is crossing over possible in multiple alleles?
Yes, crossing over can occur between multiple alleles located on the same chromosome. This can lead to the exchange of genetic material between different alleles during meiosis.
Are the genes on a recombinant chromatid the same as the original chromatid?
No, the genes on a recombinant chromatid are a combination of genes from the original chromatids. During crossing over in meiosis, genetic material is exchanged between homologous chromosomes, resulting in a new combination of genes on the recombinant chromatid.
What results in the exchange of alleles and produces now combinations of alleles?
Crossing over during prophase I of meiosis.
