Document Summary
Meiosis involves the production of 4 unique daughter cells. Gamete- a haploid (n) reproductive cell that has one set of chromosomes. Fertilization- occurs during the fusion of two gametes (one from each parent; sperm and egg) Brings 2 gametes (one from the male and one from the female) together. Gametes are n (haploid) and differ one from another gene in composition. Gametes have half the dna content of each parent nucleus (n is 0. 5 of 2n) Each parent passes on half of its genes to its offspring. Offspring inherit a unique combination (mixture) of genes from both parents= genetic. Chromosomes of the same type, size and with the same genes at identical locations are called homologs or homologous chromosomes. Table 12. 1 the number of chromosomes found in some familiar organisms. The number of chromosomes varies for different species. Made of dna (nucleic acid) located on chromosomes. Most genes program cells to synthesize proteins.
