What is the exchange of genes between homologous pairs of chromosomes?
homologous chromosomes exchange alleles during crossing over.
Explain how crossing over can unlink genes?
crossing over can unlink genes because when crossing over occurs it a portion of one chromosome is replaced by a region of a homologous chromosome and during this the alleles that were presently on that linked gene could possibly be separated
Gene maps are based on?
the frequencies of crossing over between genes
What is it called when genes swap during meiosis?
This is the process of crossing over that happens in prophase I.
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 the exchange of genes between homologous pairs of chromosomes?
homologous chromosomes exchange alleles during crossing over.
What results from the process of crossing over during prophase I?
During crossing-over, chromosomes of a homologous pair breaks and exchange genes.
Explain how crossing over can unlink genes?
crossing over can unlink genes because when crossing over occurs it a portion of one chromosome is replaced by a region of a homologous chromosome and during this the alleles that were presently on that linked gene could possibly be separated
What would happen if crossing over during meiosis didn't happen in humans?
If crossing over didn't happen during meiosis in humans, the haploid daughter cells would all have the same genes. The crossing over creates variation and causes each daughter cell to have slightly different genes.
What results from th eprocess of crossing-over during prophase 1?
During the crossing-over of pro phase 1, chromosomes of a homologous pair break and exchange genes.
Gene maps are based on?
the frequencies of crossing over between genes
What is it called when genes swap during meiosis?
This is the process of crossing over that happens in prophase I.
Why Crossing over serves as basis of determining the disease between genes during chromosome mapping?
No
Can linked genes ever be separated?
crossing over(recombination)
What is a sentence for crossing over?
Crossing over is the exchanging of genes in a homologous pair.
What is a sentence for crossing-over?
Crossing over is the exchanging of genes in a homologous pair.
How are crossing over and recombination related?
Genetic recombination occurs during meiosis cell division. As genes cross over during this process, scientists track the genes to study their linkage.
