    genomes of the offspring are virtually IDENTICAL copies of the parent's genome
    usually occurs within eukaryotes, or single-celled organisms

    II. Sexual Reproduction
    results in greater variation than in asexual reproduction
    ...
    IV. Meiosis
    While mitosis conserves chromosome count, meiosis reduces the chromosome number by half. This occurs to compensate for doubling of chromosomes that occurs during fertilization. In animals, meiosis occurs in the male and female sex organs, meaning in either the ovaries or the testes. Meiosis is is preceded by the replication of chromosomes. This single replication is followed by two consecutive cell divisions, known as Meiosis I and Meiosis II. These series of divisions result in four daughter cells, each with half as many chromosomes as the mother cell.

    Steps of Meiosis
    Interphase: Before meiosis begins, genetic material is duplicated.

    alleles for each character segregate into gametes independently of alleles for other characters
    III. Mendelian Inheritance
    the use of the Punnet square can determine the probability of acquiring specific genotypes and phenotypes
    the rule of multiplication states that the probability of a compound event is equal to the product of the seperate probabilities of the independent single events
    the rule of addition states that the probability of an event that can occur in two or more independent ways in the sum of the separate probabilities
    ...
    make predictions about future offspring
    predictions are usually statistical probabilities rather than certainties
