What is heredity?

The passage of genetic instructions (traits) from parent to offspring.

100

Sexual reproduction produces offspring that are genetically _____________ to the parents.

Similar

Some genes can be hidden or covered up by another. These are considered to be-

Recessive

100

How are traits passed from parent to offspring?

Through genes during reproduction

200

Where are genes located?

In the chromosomes

200

Who first studied heredity and the passage of traits from one generation to the next?

Gregor Mendel

What is the punnett square used for?

To determine the outcome of genetic crossings.

Why does a Punnett Square use capital and lowercase letters?

Capital = Dominant Trait Lower Case = Recessive Trait

Inherited traits that children get from their parents come from-

Genes

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

Genotype

500

How many chromomsomes do humans have?

46 or 23 pair

The sorting of chromosomes during sexual reproduction, determines -

Which traits are passed on to the offspring

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

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.
