Question 37

complete dominance

Answer 37

when one allele is completely dominant over the other.

Question 38

codominance

Answer 38

two alleles are dominant and affect the phenotype in two different but equal ways

Question 39

incomplete dominance

Answer 39

two alleles, inherited from the parents, are neither dominant nor recessive, resulting in a blend.

Question 40

polygenic inheritance

Answer 40

when multiple genes determine the phenotype of a trait

Question 41

epistasis

Answer 41

interaction between alleles in which one allele interferes with the effects of the other.

Question 42

pleiotropy

Answer 42

one gene has multiple affects on someones phenotype

Question 43

Answer 44

any cells in the body that are not reproductive

Question 46

rule of multiplication

Question 47

rule of addition

Question 48

LEARNING OBJECTIVE 5.1
Explain how meiosis results
in the transmission of
chromosomes from one
generation to the next.

Question 49

LEARNING OBJECTIVE 5.1
Describe similarities and/
or differences between the
phases and outcomes of
mitosis and meiosis.

Question 50

LEARNING OBJECTIVE 5.2
Explain how the process of
meiosis generates genetic
diversity.

Question 51

LEARNING OBJECTIVE 5.3
Explain how shared,
conserved, fundamental
processes and features
support the concept of
common ancestry for all
organisms.

LEARNING OBJECTIVE 5.3
Explain the inheritance of
genes and traits as described
by Mendel’s laws.

Question 53

LEARNING OBJECTIVE 5.4
Explain deviations from
Mendel’s model of the
inheritance of traits.

Question 54

LEARNING OBJECTIVE 5.5
Explain how the same
genotype can result in
multiple phenotypes under
different environmental
conditions.

Question 55

LEARNING OBJECTIVE 5.6
Explain how chromosomal
inheritance generates
genetic variation in sexual
reproduction.
