Which of the following is a characteristic of the evolution of new species, that is,
speciation? (Hint: Read page 451 before answering)
New species evolved from ancestral species
Speciation is shown by a node in a phylogenetic tree
When speciation results in 2 or more new species, the new species could have
experienced genetic drift, natural selection or sexual selection
When speciation results in 2 or more new species, the new species evolved changes
in traits independently of the other species
All of these answers show characteristics of the evolution of new species, that is,
speciation
Mutation can generate differences between two newly formed sister species

Analysis of mitochondrial DNA can answer interesting and important questions. For
which of the following questions would analyzing mitochondrial DNA provide NO
useful information?
I have poor muscle function, is there something wrong with my ability to make lots of
ATP?
Are you my long-lost brother?
Are you my father?

You cross a true-breeding stock of black (BB) mice with skinny (SS) toes to a stock of
white (bb) mice with fat (ss) toes. From this, you produce an F1 generation of black
mice with skinny toes (Bb,Ss). If the single genes responsible for coat color and toe
appearance do not sort independently, then you would expect to see:
more than 25% of your F2 black mice with fat toes.
more than 75% of your F2 black mice with skinny toes.

, Recall that alleles of a single gene will segregate from each other during anaphase I.
When do alleles for two different genes, located on two different chromosomes,
segregate?

Translation is the process by which:
ribosomes read the information in a DNA molecule and use it to synthesize protein.
a protein is synthesized using information in a mRNA molecule.
the information in DNA is used to synthesize an exact copy of that DNA.
an RNA molecule is used to repair damage to a related DNA molecule.
a section of DNA is used as information to generate an mRNA molecule.

a protein is synthesized using information in a mRNA molecule.
With independent assortment, the ratio of phenotypes in the F2 generation of a cross
between true-breeding strains (AA bb × aa BB) can be described as 9:3:3:1 when A
and B are dominant over a and b. To what phenotype does the "9" in the ratio refer?
recessive for both traits
