Mendelian Genetics

AP Biology· difficulty 1/5

Mendel's law of segregation states that

  • A

    Dominant alleles always mask recessive alleles in heterozygotes, determining the visible phenotype

  • B

    Alleles of different genes assort independently of one another into gametes during meiosis

  • C

    The two alleles for a gene separate during gamete formation, so each gamete carries only one allele

  • D

    Each gamete receives both alleles for a gene, preserving the parental diploid genotype intact

Explanation

Each parent passes one of its two alleles to each gamete (during meiosis I when homologs separate).
