This occurs when one allele is not completely dominant over another allele.

• crossing-over

• codominance

• tetrad

• incomplete dominance

This describes chromosomes in which one set comes from the male parent and one set comes from the female parent.

• tetrad

• multiple allele

• homologous

• polygenic trait

This refers to a structure that contains four chromatid and forms during meiosis.

• incomplete dominance

• tetrad

• mitosis

• multiple allele

This type of cell contains a single set of genes.

• haploid

• diploid

• polygenic trait

• multiple allele

This refers to the process that occurs when the number of chromosomes per cell is cut in half for the separation of homologous chromosomes in a diploid cell.

• meiosis

• mitosis

• crossing-over

• tetrad

This occurs when the phenotype of both alleles is completely expressed.

• codominance

• tetrad

• crossing-over

This refers to the process of homologous chromosomes exchanging portions of their chromatids during meiosis.
