Concept and definition
Study of heredity
Genetics
An organisms genetic composition.
Genotype
1. tt the genotype of these genes is
Homozygous Recessive
A white mouse is crossed with a black mouse. All the offspring were grey. The genes for fur color in mice show
Incomplete dominance
Unit that determines traits
Gene
Organisms that have the same pair of alleles are said to be...
Homozygous
What did Mendel use to do his experiment
Pea Plant
When neither alleles are dominant over the other.
Incomplete dominance
Form of a gene that is expressed and represented with a capital letter.
Dominant
Organisms that have a mixed pair of alleles are said to be...
Heterozygous
An organism’s phenotype is
What is: physical appearance
The process in which body cells are duplicated in order to grow and repair body tissues is called
What is: mitosis
Identical pairs of alleles for a trait are said to be ...
Homozygous
The form of the trait that is displayed (an organisms appearance).
Phenotype
For each of the genotypes below, determine the phenotype.
Purple flowers are dominant to white.

Homozygous dominant
Heterozygous
Homozygous Recessive
This applies to genetics because the formation of gametes depends on random events.
What is: Probability
Different forms of a gene
Allele
What are the 3 types of genotype?
Heterozygous, Homozygous Dominant & Recessive
Brown hair, blue eyes, tall, curly are examples of
Traits
When both alleles affect the phenotype.
What is: Codominance
