An individual has the chromosomes below where the dot represents the centromere:
EFGH.IJKL EFGKJI.HL
If a crossover event occurs between the H and I loci, what is the longest chromosome formed?
Enter your answer with no spaces between the loci and use a period as the centromere.
Longest chromosome that can be formed is:
EFGH.IJKLEFGKJI.IJKGFELKJI.EFGH
Here the crossover occur between EFGH.IJKLEFGHKGI & HL
