What is heredity?
The passage of genetic instructions (traits) from parent to offspring.

How are traits passed from parent to offspring?
Through genes during reproduction

Ee

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.
