Homozygous vs Heterozygous
Homozygous means inheriting identical alleles for a specific gene from both parents while heterozygous means inheriting different alleles

Two dark brown rabbits have four offspring. Three of the offspring are dark and one is white. What does this tell you about the parents' genes for fur color?
Dark brown is dominant and white fur is recessive. Both parents are heterozygous.

A species of cat exhibits incomplete dominance for fur color. It can be black (dominant), white (recessive), or grey. What is the genotype for a grey cat?
Heterozygous
300
Codominance vs Incomplete Dominance
In codominance, both alleles are equally expressed, resulting in a speckled/spotted offspring (e.g., AB blood type). In incomplete dominance, neither allele is dominant, blending to form a new, intermediate phenotype (e.g., red and white parents making pink offspring).

A test cross is a genetic method used to determine the unknown genotype (homozygous dominant or heterozygous) of an organism with a dominant phenotype. It involves breeding the unknown individual with a _______________ genotype. The offspring's phenotypes will then reveal the parent's genotype.
Homozygous recessive

A species of chicken exhibits codominance. A homozygous black chicken is crossed with a black-and-white checkered chicken. What are the phenotype percentages for possible offspring?
50% Black, 50% Checkered

Gene vs. Allele
Gene- segment of a chromosome that determines a trait
Allele- Versions or variations of a gene

Heterozygous
