Text Solution

Verified by Experts

(a) Chromosome Is has the most genes and chromosome Y the least. (b) Scientists have identified about 1.4 million locations, where DNA differs in single base in human beings, called single nucleotide polymorphism. Such observations help in finding chromosomal locations for disease associated sequences and tracing human history
