When two alleles in a pair are different (Bb or Mm) they are called

• homozygous

• heterozygous

• trait

• genotype

When two alleles in a pair are the same (BB or bb) they are called

• heterozygous

• gamete

• homozygous

• zygote

Law of Dominance states

• the pair of alleles for a gene will be separated into different gametes

• a dominant allele will mask the presence of a recessive allele

• during gamete formation, the distribution of the alleles is random

Law of Segregation states

• the pair of alleles for a gene will be separated into different gametes

• a dominant allele will mask the presence of a recessive allele

• during gamete formation, the distribution of the alleles is random

Law of Independent Assortment states

• the pair of alleles for a gene will be separated into different gametes

• a dominant allele will mask the presence of a recessive allele

• during gamete formation, the distribution of the alleles is random

Different forms of a gene are called

• recessive

• dominant

• gametes

• alleles
