The parental genotypes (Gg and gg) can be described as being--

• Both homozygous recessive

• Heterozygous; homozygous recessive

• Both heterozygous

• Both homozygous dominant

Which of the following genotypes is homozygous recessive?

• AA

• Aa

• aa

• None of the above

Which of the following genotypes is heterozygous?

• HH

• hh

• Hh

• None of the above

The idea that for any particular trait, the pair of alleles of each parent separate and only one allele from each parent passes to an offspring is Mendel’s principle of --

• independent assortment

• hybridization

• dominance

• meiosis
