Answer:
In humans, chromosome 1 is the largest chromosome which is composed of approximately 249 million base pairs. It roughly represents 8 percent of the total DNA content of a cell.
It contains the highest number of genes which is approximately equal to 2000 - 2100 protein-coding genes.
Chromosome Y contains the least number of genes in a human cell. It is one of the two sex chromosomes and thus, it is the 23rd chromosome.
It contains approximately 59 million base pairs which make up around 2 percent of total DNA content of a cell.
It contains around 50 to 60 protein-coding genes.
Thus, the chromosome contains the highest number of genes and chromosome Y contains the least amount of genes.
