BIOL 120 Lecture Notes - Lecture 2: Zygote, Meiosis, Gamete
Document Summary
The process by which the combinations of alleles for different genes in two parental individuals become shuffled into new combination in offspring individuals. Haploid cells fuse during sexual reproduction to form a diploid zygote. The division of diploid cells to haploid progeny, consisting of two sequential rounds of nuclear and cellular division. The mode of reproduction in which male and female parents produce offspring through the union of egg and sperm generated by meiosis. The fusion of the nuclei of an egg and sperm cell, which initiates development of a new individual. Organism or cell with only one copy of each type of chromosome. Organism or cell with two copies of each type of chromosome. The chromosome derived from the female parent of an organism. The chromosome derived from the male parent of an organism. Chromosomes that are different in male and female individuals of the same species.
