An organism's complete genetic makeup. Or a specific genetic formation, such as a heterozygous form
What is a genotype
100
The physical appearance of an organism; the outer expression of its genotype

Heredity works by a combination of chance, or what we also call...

Probability

The grid where we determine each possible genetic outcome an offspring may have
What is a Punnett square
300
A genotype that contains two of the same allele
