NEET BIOLOGY

Detailed explanation-1: -Diploid is a term that refers to the presence of two complete sets of chromosomes in an organism’s cells, with each parent contributing a chromosome to each pair. Humans are diploid, and most of the body’s cells contain 23 chromosomes pairs.

Detailed explanation-2: -Definition. A cell containing two copies of each chromosome is referred to as a ‘diploid cell’; human somatic cells are diploid: they contain 46 chromosomes, 22 pairs of autosomes and a pair of sex chromosomes.

Detailed explanation-3: -Haploid. A haploid cell has only a single set of chromosomes. Most cells in humans are diploid rather than haploid, meaning they have two copies of each chromosome.

Detailed explanation-4: -In humans, special cells called germ cells undergo meiosis and ultimately give rise to sperm or eggs. Germ cells contain a complete set of 46 chromosomes (23 maternal chromosomes and 23 paternal chromosomes).

Detailed explanation-5: -The zygote represents the first stage in the development of a genetically unique organism. The zygote is endowed with genes from two parents, and thus it is diploid (carrying two sets of chromosomes).
