Question

Syntenic genes can assort independently when:_________.

1. they can assort independently when they are very close together on a chromosome.
2. crossing over occurs rarely between the genes.
3. they are located on different chromosomes.
4. they are far apart on a chromosome and crossing over occurs frequently between the genes.
5. they are far apart on a chromosome and crossing over occurs very rarely between the genes.

Answer 1

4.

Step-by-step explanation:

Synteny oe syntenic gene is defined as the physical co-localization of genetic loci on the same chromosome within a speciesand inidvidual.

In the beginning of the meiosis process, when genes are present in the same chromosomes but very far, they undergo indepedent assort due to homologous recombination and the random exchnage of matching fragment in homologous chromosomes takes place. During the crossing over there are very less chances that all types of gametes are produced accurate frequency.

Hence, the correct answer is 4.
