Question

the human chromosome with highest and least number of genes are

Answer 1

X and Y chromosomes respectively

Answer 2

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.
