incomplete dominance
Give this one a try later!
A pattern of inheritance in which two alleles, inherited from the parents, are
neither dominant nor recessive. The resulting offspring have a phenotype
that is a blending of the parental traits.
,Explain why incomplete dominance is not the same as blending inheritance. Why do
we need to do two crosses and examine the F2 generation to rule out blending
inheritance?

Blended inheritance will not have the parent phenotypes present in the F1
cross, but incomplete dominance will. Looking at the F2 generation for the
parent phenotypes can help distinguish between the two
We know that some aspects of human health are affected by the microbiome. Which
specific aspects of human health are significantly affected by the microbiome? (Hint:
this question is asking you to read a figure).

The taking of antibiotics. It can cause an extreme disturbance in the gut

all the microorganisms living in association with an organism including

the sex chromosome found only in males. When paired with an X
chromosome from the mother, it produces a male child.
What events occur in G1, S, G2, and M phase of the cell cycle? Which of these phases
are within interphase? When in the cell cycle do mutations occur?
Give this one a try later!
G1 phase: cells grow, organelles are copied
S phase: DNA is replicated
G2 phase: general prep for mitosis
M phase: Mitosis and cytokinesis
G1, S, and G2 together make up interphase
Mutations occur during S phase because that is when DNA replication
happens
What results from mitosis? How does mutation affect the results of mitosis?

, 2 daughter cells with the same DNA as the parent cell. Mutation changes
the DNA of the daughter cell so that it is no longer identical to the parent
How do we use information on a genetic map? How do you use a genetic map to
determine whether a specific gamete or offspring phenotype will be common or
rare?
Give this one a try later!
It helps us to determine how the physical distance between genes
influences the frequency of crossing over between them. If genes are
closer together, crossing over will be more rare. If genes are further apart,
crossing over is common
advantageous mutation

a mutation that increases the carrier's chances of survival
How does mitotic cell division in a multicellular organism affect the DNA that is
present in different types of somatic cells (e.g. skin cells, muscle cells, heart cells, liver
cells, etc.)? Do all cells have the same DNA, or do different cells have different DNA?
