Front

Which of the following is correct? Yy is homozygous dominant., YY is heterozygous., yy is homozygous recessive., YY is homozygous recessive.

Back

yy is homozygous recessive.

Front

Which of the following best describes Mendel's law of dominance?

• When an organism has two different alleles of the same gene, both genes will be expressed equally.
• When an organism has two alleles, one of genes will be expressed and the other will be hidden.
• When an organism has two different alleles of the same gene, one will always be dominant.
• The stronger of the two genes will be expressed.

Back

When an organism has two alleles, one of genes will be expressed and the other will be hidden.
