Front

The inheritance of biological characteristics is determined by what?

Back

Genes passed from parents to offspring.

Front

Can two or more forms of the gene for a single trait exist?

Back

Yes, they can exist.

Front

What happens to the copies of genes when gametes are formed?

Back

They are segregated from each other.

Front

How do alleles for different genes usually segregate?

Back

Independently of one another.

Front

When two or more forms of the gene for a single trait exist, what may some forms be?

Back

Some forms may be dominant and others may be recessive.

Front

Do all genes show simple patterns of dominant and recessive alleles?

Back

False, not all genes show simple patterns.

Front

Patterns of Inheritance: Incomplete Dominance

Back

One allele is not completely dominant over another. The heterozygous phenotype is somewhere in between the two homozygous phenotypes.
