Which correctly describes crossing over?
ollegr [7]

The correct option is A ie the process whereby non-sister chromatids exchange genetic material

  • Between prophase I and metaphase I, a process known as crossing over occurs in which two homologous non-sister chromatids join up and exchange various pieces of genetic material to create two recombinant chromosome sister chromatids.
  • When genetic material is switched between two chromosomes, this process is known as crossing over.
  • It is in charge of causing genetic variation among members of a species.
  • Only the reproductive cells known as gametes undergo this process.
  • The steps involved in crossing over are as follows:

1) Synapsis.

2) Chromosome duplication

3) Crossing over.

4) Terminalizataion.

What is well-tested explanation that brings together many observations in science would include such things as evolution, plate
lara31 [8.8K]

The correct answer is a theory.  

A theory is a rational and contemplative kind of generalizing or abstract thinking or the outcomes of such thinking. On the basis of the context, the outcomes might involve generalized illustrations of how nature functions.  

A theory can be a source of knowledge that may or may not is related to the specific explanatory models. To theorize is to create the body of knowledge.
