What is an allele?

Multiple Choice

Which allele is expressed if it is present?

• Dominant allele

• Recessive allele

Multiple Choice

How is the dominant allele represented?

• a capital letter

• a lower case letter

Poll

What is this called??

• Pedigree

• Punnett Square

• That box thing

Punnett Square

Shows all of the possible allele combinations that an offspring can receive.

How many pea pods are yellow and how many are green? How do we know?

Multiple Select

Which options are considered types of inheritance patterns?

• Codominance

• Incomplete Dominance

• Polygenic Traits

• Multiple Alleles

Multiple Alleles

3 or more forms of a gene (allele) for a specific trait

Ex. Blood Typing

Polygenic Trait

an inheritance pattern in which the trait is controlled by many (poly) genes

Ex. Skin color - many genes control it!

Codominance

Alleles are neither dominant nor recessive. Both alleles are expressed (or seen)

Ex. Roan cows

Incomplete Dominance

Neither allele is dominant and offspring shows an in-between of the parents

Ex. Red + White flowers = Pink Flowers

Multiple Choice

This flower would be an example of which inheritance pattern?

• polygenic traits

• incomplete dominance

• multiple alleles

• codominance

Poll

It takes many different genes, on different chromosomes to determine height. Which inheritance pattern would explain height?

• polygenic traits

• multiple alleles

• codominance

• incomplete dominance

Poll
