Organisms that reproduce sexually have specialized cells called gametes (sex cells). Gametes are the result of a type of cell division called meiosis. Diploid and haploid. Almost all human cells are . Meiosis. Meiosis is the cell division which produces the . sex cells . or . gametes. .. Meiosis occurs in the cells of the . reproductive organs. :. Sperm cells – testes. Ova (eggs) – ovaries. Pollen - anthers. Sexual Life Cycles. Which of the following transmits genes from both parents to child, or from one generation of a family to another?. DNA. gametes. somatic cells. mitosis. nucleotides. Which of the following transmits genes from both parents to child, or from one generation of a family to another?. Before we start genetics, let's review the process of what makes us all look different compared to our siblings, family, and classmates!. Sexual Reproduction.
