Fertilization is the process of

• the joining of the male an female reproductive cells

• cloning

• the development of an embryo

• recessive traits being masked

A specific characteristic of an individual, such as seed color or plant height, is known as a

• gene

• allele

• hybrid

• trait

A hybrid is an offspring resulting from

• parents with the same traits

• parents with different traits

• genes

• alleles

• hybrids

• traits

Mendel's principle of dominance states that

• all alleles are dominant

• all alleles are recessive

• some alleles are dominant and some are recessive

• organisms only display recessive alleles

Segregation of alleles refers to the fact that

• both alleles for a gene from each parent are passed down to offspring

• one allele for a gene from each parent are passed down to offspring
