Mendel originally referred to these
as “factors” but we now know them
as:
Genes
What principle states that some
alleles will always show and
some will only show when there
are two present?
Principle of dominance
If one pea plant that is
heterozygous for height crosses
with another that is homozygous
recessive for height, what is the
rd
chance that their 3 offspring
will be tall?
50 % chance, same chance as their
first offspring, and their 34th
offspring….
Name 4 differences between meiosis
and mitosis:
Mitosis -2 cells, genetically
identical, only 1 division, somatic
cells, 46 chrom.
Meiosis-4 cells, genetically different,
2 divisions, sex cells, 23 chrom.
Why are gametes genetically
different? (what happens and
when?)
Crossing over, prophase 1
What is a two word term that
could be used to describe a
DNA molecule?
Double helix
*courtesy of Watson and Crick!
What are the four DNA bases, what
do they bond with, and what type of
bonds hold them together?
Adenine-Thymine
Guanine-Cytosine
*Hydrogen bonds hold them
together
What are three differences
between RNA and DNA?
Single stranded, uracil, ribose sugar
Where does transcription happen
and what do it make?
Nucleus, mRNA
Genes are used to make ________ which are
made using ______________. These two
structures also help.
Proteins, amino acids
tRNA, mRNA

What team is going to win the

Name both of the authors to your
textbook
Miller and Levine
On the first day of spring how many
hours of sunlight are there?
12
I want a type of soybean that grows
quickly and produces a high yield,
but I am completely apposed to
genetic engineering (manipulating
DNA), what should I do?
Selectively breed
Why would a person want to
produce a hybrid?
To get the best traits of two different
parents into an offspring
Why don’t clones that get their DNA
from udder cells just grow into
udders?
Because certain genes in the DNA
have been turned on or off telling the
cell to grow into an embryo instead
because of the nucleus being put into
the egg cell.
How can scientists change genes in a
gene pool?
Inducing mutations
Polyploids (changes chrom. #)
What genetic engineering process
uses plasmids?
transformation
What are two phenotypes that
could both result in type A
blood?

If a pedigree has carriers you
know the trait is …..
recessive
Give an example of how
nondisjunction could effect sex
chromosomes
XXX, XXY, X0…etc.
If a man who has type AB blood
marries a women is homozygous
for type A blood, what are the
chances their child will have type
B blood?
0%
2 part:
1. What is hemophilia?
2. What “type” of disease is it and
who gets it most often? Why?
1. Protein that allows for blood
clotting is missing
2. Sex-linked, men get it more
because it is recessive and
located on the X chrom.
