What type of gene causes traits that are less
likely to occur?
WHAT IS A RECESSIVE GENE
Which of these is due entirely to inheritance
in humans?a. Eye color
b. Reading skillc. Endurance
d. Broken bones
B- EYE COLOR

Mendel’s early work with pea plants demonstrated a
significant genetic discovery. The crossing of homozygous
tall pea plants with homozygous short pea plants always resulted in tall plants and demonstrated that tallness in pea plants is a
trait that is:
What is Dominant
A lizard re-growing a lost tail is an example of what?
What is Regeneration
New yeast grows on a parent yeast organism, and breaks off when it is ready to form a new
separate organism.
What type of reproduction is this an
example of?
What is Asexual Reproduction
Which of the following traits of a dog is inherited from the
parents?a. The presence of fleas in its fur
b. The color of its furc. The ability to sit up and beg
d. The habit of barking to go outside
What is b- the color of its fur
Each form of a gene is called an allele. The alleles for human
blood type are A, B, and O. Both the allele for type A blood and B blood type are dominant. The
allele for type O blood is recessive. What blood type will a person if he inherits an allele for type A and an allele for type
O?
What is type A
The chances of developing cancer, diabetes, or sickle-cell anemia are higher if a family member also has the disorder
because they are -a. Highly infectious
b. Passed through blood contactc. Genetically based
d. Related to diet
What is C- genetically based
Why is DNA essential to living organisms?
What is it carries the genetic code
What type of gene causes traits that are more likely
to occur?
What is a dominant gene
What are the possible genotypes of the
offspring from a cross between two people with genotypes Bb?
What are X

When a cell of a plant stem divides, each new cell has how
many chromosomes?
What is the same number of chromosomes as the parent
cell
The physical expression of a genetic trait is called what?
What is it’s phenotype
In humans, having bushy eyebrows is a trait that is
dominant over having thin eyebrows. Two parents with bushy eyebrows are going to
have a baby. What can be predicted about how the baby’s
eyebrows will develop?
What is the baby most likely will have bushy eyebrows
I have green eyes and you might have brown eyes. Different eye
color is caused by what?
What is different combinations of genes for eye color
In pea plants, purple flowers are dominant to white flowers.
Suppose a purple flowered plant with genotype Pp is crossed with
another purple flowered plant with the same Pp genotype.
What percentages of offspring will also have purple flowers?
What is 75%
The allele for black hair, B is dominant to orange tabby color,
b, in cats. Based upon the Punnett square below, what did
the parents look like in this genetic cross?
Bb bb

What is one black parent Bb and one tabby parent bb
How much genetic material is found in a cloned cell as
compared to the original cell?
What is the same amount?
Brown eyes are dominant to green/blue eyes. Both of my
parents had brown eyes, but I had green eyes. What is the BEST
explanation for why I have green eyes?
What is both of my parents carried a gene for green/blue eyes

Poodles, like all dog breeds, are so closely related to wolves that they can breed with them. What is the best explanation for why wolves and poodles do not look alike, despite being extremely
close relatives?
What is poodles are the result of people selectively breeding them
for specific taits
What are the chances of having homozygous recessive offspring
if the father is homozygous dominant for brown hair and the
mother is heterozygous for brown hair?
What is 0%

What is true of the offspring of organisms that reproduce
sexually?
What is they have some genetic traits of both parents, but are not
exactly like either.
The process of an organism passing on its traits to its offspring is called what?
What is heredity
If you selectively breed two German Shepherds that are
homozygous dominant for a trait. The resulting offspring will be
examples of what?
What is a purebred
