Question

which of these gametes contains one or more recombinant chromosomes? a and c a and d a and b d and e b and c

Explanation:

Recombinant chromosomes are formed through crossing - over during meiosis. Gametes with recombinant chromosomes will have a combination of genetic material that is different from the parental (non - recombinant) combinations.

• In the first set of gametes (from the left - hand pair of parent cells), gamete A has non - recombinant chromosomes (both chromosomes are of one color, either all blue or all red in their respective segments as per the parent - like pattern). Gamete B has recombinant chromosomes (a combination of blue and red segments on different chromosomes). Gamete C has recombinant chromosomes (a different combination of blue and red segments on different chromosomes).
• In the second set of gametes (from the right - hand pair of parent cells), gamete D has non - recombinant chromosomes (chromosomes have a parent - like color pattern). Gamete E has non - recombinant chromosomes (chromosomes have a parent - like color pattern).

Answer:

B and C
