which of the following statements correctly describes the characteristics of recombinant chromosomes?
they carry genes from only one parent.
they contain more genes than nonrecombinant chromosomes.
they are identical in genetic makeup to the parental chromosomes.
they carry genes from two different parents.

Explanation:

Recombinant chromosomes are formed during meiosis through crossing - over. This process involves the exchange of genetic material between homologous chromosomes (one from each parent). So, they carry genes from two different parents.

• The first option is wrong because they carry genes from both parents, not just one.
• The second option is incorrect as the number of genes is not more than non - recombinant chromosomes.
• The third option is wrong since they are not identical to parental chromosomes due to genetic recombination.

Answer:

They carry genes from two different parents.
