What is a pedigree?
300
The process in which DNA is split in two and complimentary bases are added to the two halves in order to create two copies of the original DNA molecule.
What is replication?
300

An allele that contributes to the phenotype if it appears at least once in the genotype.

What is a dominant allele?
300
An organism with a genotype consisting of two of the same alleles, dominant or recessive.

500
A segment of DNA which determines a single trait.
What is a gene?

500
Physical traits.
What is a phenotype?
500

This is when there are two different factors that mix to create a heterozygous individual's phenotype.

What is incomplete dominance?
