Answer: 92 Chromatids
Explanation: A chromatid is one of the two strands that form when a chromosome duplicates itself during cell division. Before DNA replication, the somatic cell has 46 chromosomes. Subsequently after the DNA replication, each chromosome will possess two physically attached sister chromatids, the chromosomes will condense to form compact structures (though it'll still be made of two chromatids). Thus, after replication, there would be 92 chromatids.
If a cell that has three pairs of chromosomes, the fraction of the gametes produced from this cell will contain only maternal chromosomes would be 1/8.
In this case, the cells have three pairs of chromosomes. Then, the calculation to find the fraction would be: (1/2)^3= 1/8
A scientific theory explains the reason for the occurrence of phenomena. However, a scientific law is limited to applicability and does not give any explanation regarding the phenomena in which it can be applied to.
