Question 1

proportionate heritability

Answer 1

the amount of phenotypic variance
that can be explained by genes
in a given population

Question 2

epigenetics

Answer 2

changes to
an organism’s phenotype
resulting from modifications
to gene expression

Question 3

gene expression

Answer 3

the process of
reading the information stored
within a gene to create a functional
product, typically a protein

Question 4

transcription

Answer 4

the process
whereby a sequence of DNA is
used to produce a complementary
sequence of mRNA

Question 5

translation

Answer 5

the process whereby
an mRNA sequence is used to
produce a protein

Question 6

DNA methylation

Answer 6

the process by
which methyl (-CH3
) groups are
added to particular nucleotides in
a DNA segment so as to modify
the expression of a gene

Question 7

somatically heritable

Answer 7

genetic
traits or alterations to a cell which
are inherited by daughter cells
during the course of regular mitotic
cell division

Question 8

DNA methylation 

Answer 8

the process by
which methyl (-CH3
) groups are
added to particular nucleotides in
a DNA segment so as to modify
the expression of a gene
