The type of reproduction
that requires 2 parents
What is sexual reproduction?
Back to you Alex
200
The type of reproduction
that creates very little
diversity (differences) in a
species?
What is asexual reproduction?
Back to you Alex
300
2 differences between plant
and animal cells
What is plant cells have cell walls, a
square shape, one large vacuole and
chloroplasts?
(s)

The 3 major ideas of Cell
Theory
What are:
-all living things are made of cells
-all cells are produced from other cells
-cells are the basic unit of structure &
function in living things?

A section of DNA that controls a
certain trait
What is a gene?
Back to you Alex
100
The study of heredity
What is Genetics?
Back to you Alex
200
An inherited physical
characteristic
What is a trait?
Back to you Alex
300
Different forms of a gene
Daily Double
What are alleles?
Back to you Alex
400
The passing of traits from
parents to offspring
What is heredity?
Back to you Alex
500
He is credited as being the first
to explain the process of
heredity
Who is Gregor Mendel?
Back to you Alex
100
He created a tool that scientists
use to predict the outcome of
genetic crosses
Who is Reginald Punnett?
Back to you Alex
200
This is used to show all possible
combinations of parents’
alleles
What is a Punnett Square?
Back to you Alex
300
Two ways environmental
factors can affect eyesight
What are:
Light exposure, overuse, injury
etc.?
Back to you Alex
400
Right-handedness is dominant
to left-handedness.
This represents the dominant
allele.
What is “R”?
Back to you Alex
500
The probability of a homozygous
right-handed person (RR) and a lefthanded person (rr) having a child that
is left-handed.
What is 0%?
Back to you Alex
100
Right-handedness is dominant to
left-handedness.
This is the genotype of a
heterozygous person
What is Rr?
Back to you Alex
200
Right-handedness is dominant to
left-handedness.
This is the phenotype of a
heterozygous person
What is right-handed?
Back to you Alex
300
If you cross a white cow and a black
cow, you get offspring that are both
black and white.
That means black and white coat
colors must be this
Daily Double
What is codominant?
Back to you Alex
400
Color-blindness is a recessive trait.
The reason a colorblind person
can never be hybrid
What is a hybrid would have
Cc (normal vision)?
Back to you Alex
500
Brown eyes (B) are dominant to blue
eyes (b).
The probability for the offspring in the
Punnett Square below
What is 75%
chance of brown
eyes & 25%
chance of blue
eyes?
Back to you Alex
100
Right-handedness (R) is dominant to
left-handedness (r).
The probability for the offspring of
parents who are homozygous lefthanded and heterozygous righthanded
What is 50% chance of right-handed and
50% chance of left-handed?
Back to you Alex
200
In mice, black fur (B) is dominant to
white fur (b).
The genotypes that could result from a
cross between 2 heterozygous mice
What are BB, Bb, and bb?
Back to you Alex
300
Brown eyes (B) are dominant to blue
eyes (b).
The reason the offspring of a purebred
brown-eyed person must have brown
eyes
What is the offspring must get at least
one “B”, which would give them
brown eyes?
Back to you Alex
400
The reason you don’t need a Punnett
Square to determine the offspring of
asexual reproduction
What is asexual reproduction produces
offspring identical to the parent?
