Question

What is the genetic benefit of the process below?
It increases the likelihood that an organism will survive in a new environment.

It creates new combinations of genes on a chromosome and leads to variation.

There is no benefit; it is often a disastrous event.

It results in the conservation of parental genes to offspring.

Answer 1

Answer:

it creates new combination of genes on a chromosome and leads to variations

Answer 2

The correct option is - It creates new combinations of genes on a chromosome and leads to variation.

The process shown in the diagram is called crossing over. It occurs in meiotic cell division or reductional cell division. It occurs in prophase I of meiosis I.

It is a very important process to maintain variation and diversity among organisms. Prophase I of meiosis I consist of five stages.

They are namely, leptotene, zygotene, pachytene, diplotene and diakinesis. Crossing over occurs in the pachytene stage of prophase I.
