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

How are traits passed from parents to offspring? 

What is through genes and chromosomes during reproduction?
100
Some genes can be hidden or covered up by another. These are considered to be-
Recessive

What does heterozygous mean in genetics? 

Two DIFFERENT alleles (Rr)

Inherited traits that children get from their parents come from-

Genes

400
The physical trait observed in an offspring is known as it's -
Phenotype
400
For some traits, only one copy of a particular gene is needed to show a given trait. These genes are referred to as-
Dominant
400
Having dimples is dominant (D). Not having dimples is recessive. (d) Both parents are heterozygous for the dominant trait. What percentage of the children will NOT have dimples?
25%

What is cell, organism, population, ecosystem?

How many chromomsomes do humans have?
46 or 23 pair

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.

500
Long ears are dominant (E) in rabbits. If one parent is homozygous dominant for the long ear trait and the other homozygours reccessive (e), what is the only possible genotype of the offspring?
Ee
