An individual has the chromosomes below where the dot represents the centromere: ABCDEFG. H AEDCBFG. H If a crossover event occurs between the B and C loci, what is the longest chromosome formed?

In the given sequence of chromosomes to represents the centro-mere is ABCDEFG.H AEDCBFG.H.

In case of crossing over among B and C, made recombinants will be;

1) ABCDEA  

2) H.GBCDEFG.H

However, out of these two made crossover chromosomes, only 1st recombinant chromosome as ABCDEA is the straight recombinants chromosome .

so whats the answer

well for one plants are always the producer, so a is the answer. a wolf is more of the consumer(predator) and the deer is the prey so i know those two are out of the question. also mushrooms are fungi/fungus so a is the producer.
