1. What is a Haploid Genome?
The term "haploid" refers to a single set of chromosomes. In humans and many other organisms, the haploid genome consists of 23 chromosomes, which is half of the 46 chromosomes found in diploid somatic cells. The haploid genome is critical for sexual reproduction, as it combines with another haploid genome from the opposite sex to form a diploid zygote.
1.1 Characteristics of Haploid Genomes
- Contains a single set of chromosomes.
- Essential for the formation of gametes.
- Provides genetic diversity through recombination during meiosis.
2. Significance of the Haploid Genome
The haploid genome is significant for several reasons:
