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 is the nucleus

200
Where are genes located?
In the chromosomes

What is a probable reason that a trait skips a generation?

What  is recessive?

400

Inherited traits that children get from their parents come from-

Genes

400

The different forms of a gene.

alleles


400

For some traits, only one copy of a particular gene is needed to show a given trait. The gene that always shows up. These genes are referred to as

Dominant

400

The likelihood that a particular event will occur.

probability

Sexual Reproduction takes how many parents to produce an offspring.

2 parents

What do we call the genetic make up of the individual, represented by a set of letters?
Genotype

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.
