This type of inheritance pattern is a MIXTURE of both traits, like the old theory of blending

incomplete dominance

co-dominance

complete dominance

recessive pattern

This type of inheritance pattern shows BOTH traits in possible offspring:

complete dominance

incomplete dominance

co-dominance

Indomitable

When two or more genes control one single trait.

Multiple Alleles

Several Genes

Polygenetic Traits

Genotype

When two or more alleles for a trait exist in a population. Ex: Different hair colors or blood types

SHAZAM!

Multiple Genes

Multiple Alleles

What is a possible phenotype of a child that results from a woman with type AB blood and a man with type A blood?

type O

type A

A father that is heterozygous blood type A is crossed with a heterozygous blood type B mother. What will be the genotype of the offspring?

50% AB; 50% OO

25% AB, 25% AO, 25% BO, 25% OO

25% AA, 25% BB, 25% AB, 25% OO

100% AB

A father that has blood type O is crossed with a blood type O mother. What will be the genotype of the offspring?

50% AB; 50% OO

25% AB, 25% AO, 25% BO, 25% OO

25% AA, 25% BB, 25% AB, 25% OO

100% OO

A red eyed female fruit fly X^R X^Ris crossed with a white eyed male X^r Y. What are the phenotypes of the offspring?

2 red eyed females; 2 red eyed males

2 white eyed females; 2 red eyed males

2 white eyed females; 2 white eyed males

1 red eyed female; 1 white eyed female; 1 white eyed male; 1 red eyed male

There are three common alleles for the gene that controls blood type. These are A,B, and O. Their Dominant/recessive relationship is:

A and O are codominant and B is recessive

O is dominant and A and B are corecessive

A and B are codominant and both are dominant to O

B and O are codominant and both are dominant over A

10.

Which best describes polygenic traits?

They are controlled by more than one gene.

They are always controlled by two genes.

They are recessive traits.

They are dominant traits.

11.

Human blood is unique in that it has 3 different alleles. How many total genotypes are possible from those alleles (A, B, and O)?

12.

How many total phenotypes are possible from alleles used to express human blood types (A, B, and O)?

13.

Hemophilia is a recessive sex-linked condition. A carrier mother reproduces with a healthy father. Which scenario may occur under these circumstances?

They will never produce a carrier daughter.

They will always produce hemophiliac daughters.

They will never have a hemophiliac son.

A hemophiliac son may be born to that couple.

14.

Which best describes why sex-linked conditions are more often found in males?

Males often inherit the defective gene on the Y-chromosome.

Males must inherit both alleles on the X-chromosome.

Males only inherit one allele (from the mother) on the sex chromosome pair.

Males only inherit one allele (from the father) on the sex chromosome pair.
