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.

Answer:

The correct answer is : The dominant form of the trait shows.

Explanation:

In simple dominance, the attribute related to the prevailing or dominant allele is communicated while the character related to the latent or recessive allele is persecuted or masked. For instance –  

Taking a bloom where the dominant allele attribute is red shading and the recessive allele characteristic is white shading. At the point when a posterity of this bloom is created containing one prevailing or dominant allele and one passive allele, its shade would be red simply because just the predominant allele communicates its characteristic.  

Thus, the right answer is: The dominant form of the trait shows.
