Genetics and blood typing review

Mendel believed that the characteristics of pea plants are determined by the

• Traits of both parents

• The health of the paretns

• The pollenation of the parents

• The traits of one parent

Which of the following describes the difference between genotype and phenotype?

• genotype is the physical traits we see and phenotype is the names given to alleles of a gene

• genotypes are the genes that are passed down; phenotypes are the different versions of those genes

• phenotypes are the genes that are passed down; genotypes are the different versions of those genes

• genotype refers to the alleles for a given gene; phenotype refers to the trait that you can see

Which of the following is NOT true about blood typing?

• There are only 2 antibodies

• Only A and B are codominant

• Type O blood is codominant with A and B

• There are three alleles

What happens to a patient is given the wrong blood type during a transfusion?

• Nothing blood type does not matter much when giving someone a blood transfusion

• The patient would be fine after a period of adjustment and would go home feeling better

• The antibodies in the patient would reject the antibodies in the blood recieved causing problems

• The antibodies in the patient would adapt to the antibodies that were recieved causing pain

In flowering plants, offspring will sometimes show a phenotype different from their parents. This new phenotype represents a blending of the trait shown by each of the parents. This inheritance pattern is called

• complete dominance

• codominance

• polygenic traits

• incomplete dominance

Mary had type A blood. Her son Bill has type AB blood. Which blood type does Bill's dad have if he is homozygous for blood type?

• A,O

• A,B

• B

• A,B,O

  If a person has type B blood, which statement describes the antibodies present in his or her blood?

• B, O

• B only

• A.B.O

• A,B

An allele is

• a homozygous genotype

• another word for a gene

• one of several possible forms of a gene

• a heterogenous genotype

Which is an external environmental factor that affects how inherited traits are expressed?

• nutrition

• gender

• structural difference

• hormones

A brown guinea pig is mated with a white guinea pig. Their offspring are brown with white splotches. Which inheritance patterns does this show?

• complete dominance

• incomplete dominance

• codominance

• polygenic dominance
