What else can I help you with?
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.
How does crossing over affect alleles on a chromatid?
cancer
What are the characteristic of multiple alleles?
1) Multiple alleles are always on the same location (locus) on the alleles.2)they always effect the same character.3)They always occupy the same gene locus on chromosome.4)no crossing over is known to occur on chromosome.5)a single multiple allelic series affects only one trait _eye color etc
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.

What results in the exchange of allels and produced new combinations of alleles?
Crossing-over
How does crossing-over affect the alleles on a chromatid?
cancer
What is the process in which DNA changes to form new alleles?
Crossing-over
How can crossing-over between two alleles be used to map their locations on the chromosomes?
The percentage of crossing-over for two traits is proportional to the distance between them on a chromosome. Sturtevant defined one map unit as a frequency of crossing-over of one percent.
Which phase is crossing over occur and why is crossing over important?
Crossing over isn't neccessarily a named stage but is when alleles "jump" over to other parts of the chromosome resulting in greater genetic variation. That way the population isn't in a word having children with their cousins.
What are the Characteristics of multiples?
1) Multiple alleles are always on the same location (locus) on the alleles.2)they always effect the same character.3)They always occupy the same gene locus on chromosome.4)no crossing over is known to occur on chromosome.5)a single multiple allelic series affects only one trait _eye color etc
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
