Cells are the fundamental units of life, containing various components like the nucleus, mitochondria, and DNA. Genes, located within chromosomes in the nucleus, determine inherited traits through alleles and genotypes, showcasing the intricate genetic makeup of individuals.
The process of sexual reproduction involves the combination of haploid gametes from both parents to form a diploid zygote, initiating the development of a new organism through mitosis. Understanding the distinction between somatic cells (2n) and germ cells (n) provides insights into the mechanisms underlying genetic inheritance and the creation of offspring.
