The different number of maternal and paternal chromosomes possible will be 8. that is option A is correct.
Chromosomes are defined as the genetic material within the body. They are thread like structures within the DNA and are made of proteins. In general human body has 23 pairs of chromosomes out of which 22 are numbered while 1 is the sex chromosome. Gametes are genetic material that are generally haploid in nature and they carry only one chromosome along with them. According to the question, there are 6 diploid chromosomes present which means there are 3 pairs of chromosomes. So each gametes will have a total number of 3 chromosomal pairs irrespective of their type that is maternal or paternal. Therefore combination of maternal and paternal chromosomes are given by
Combination = 2ⁿ where n is pair of chromosomes and here n = 3
Combination = 2³ = 8
