Question 1
The diagram shows a DNA fingerprint from a cow and four calves. Which of these is MOST LIKELY the calf of this cow?
a
Calf 1
b
Calf 2
c
Calf 3
d
Calf 4
Question 2
This human karyotype is unusual because chromosome set –
a
5 has chromosomes of different shapes
b
21 has an extra chromosome
c
10 is missing genetic material
d
14 has enlarged centromeres
Question 3
Read the passage about stem cells.
Present in all kinds of tissues, stem cells have the unique ability to develop into other kinds of cells if necessary. An organism's stem cells can transform into brain cells, blood cells, muscle cells, or any other specialized cell found in the organism. Planarian worms have an extremely high stem cell count throughout their bodies.
Which answer best describes an advantage to a planarian worm from having a high stem cell count?
a
a planarian worm's cells can never truly die
b
planarian worms can adapt to any environmental changes
c
planarian worms are able to evolve faster than other organisms
d
a whole new planarian worm can grow from a tiny piece of another
Question 4
The diagram shows a cross between two pink flowers.
What is the role of meiosis in creating variations in the offspring of this cross?
a
Meiosis allows alleles to separate, decreasing the variety of colors of the offspring.
b
Meiosis allows alleles to separate, increasing the variety of colors of the offspring.
c
Meiosis allows alleles to stay together, increasing the variety of colors of the offspring.
d
Meiosis allows alleles to stay together, decreasing the variety of colors of the offspring.

Question 6
In rabbits, white fur (W) is dominant to black (w), and long ears (E) are dominant to short ears (e). A breeder mates two rabbits that are heterozygous (WwEe) for both traits.
What is the chance that the offspring will be white with long ears?
(You may use the easy quick method to solve. Hint= set up 2 monohybrid crosses and multiply)
a
1/16
b
3/16
c
8/16
d
9/16
Question 7
What is the phenotype with a rabbit with the genotype of Bb Gg
a
black eyes with white hair
b
black eyes with gray hair
c
red eyes with black hair
d
BbGg
Question 8
Premium Photo | Three little orange striped kitten on white background high resolution A common trait found in orange tabby cats is the following: being awesome (A) is dominant to being average (a).
A male cat that is homozygous dominant for the A trait is mated with a female cat that is homozygous recessive.
For a cross with four offspring, what is the probability that they will have an offspring who is heterozygous?

Question 9
On an extraterrestrial planet, which had organisms that reproduced with DNA the same way that organisms on Earth do, green little organisms have eyes that are triangular or round. Triangular eyes (T) are dominant to round eyes (t). A Punnett square was made to predict the offspring of two of these extraterrestrials with the genotypes Tt and tt. Use the Punnett square below to answer any questions that follow.
According to the Punnett square, what is the probability that an offspring would have triangular eyes?
a
0:4
b
1:4
c
2:4
d
3:4
e
4:4
Question 10
Clouded leopards are a medium-sized, endangered species of cat, living in the very wet cloud forests of Central America. Assume that the normal spots (XN) are a dominant, sex-linked trait and that dark spots are the recessive counterpart.
Suppose, as a Conservation Biologist, you are involved in a clouded leopard breeding program. One year you cross a male with dark spots and a female with normal spots. She has four cubs and, conveniently, two are male and two female. One male and one female cub have normal spots and one each have dark spots.
What is the genotype of the mother for this sex-linked trait?
a
heterozygous
b
homozygous
c
impossible to determine with given information
d
purebred for normal spots
Question 1: The most likely calf of this cow is not indicated in the given information.
can you answer all the questions plz
Apologies for missing the previous response. Here are the answers to all the questions:
Question 1: The most likely calf of this cow cannot be determined based on the given information.
Question 2: The human karyotype is unusual because chromosome set 21 has an extra chromosome.
Question 3: The advantage to a planarian worm from having a high stem cell count is that a whole new planarian worm can grow from a tiny piece of another.
Question 4: Meiosis allows alleles to separate, increasing the variety of colors of the offspring.
Question 5: The genotype expected in the bottom right-hand corner (red square) is ggbb.
Question 6: The chance that the offspring will be white with long ears is 9/16.
Question 7: The phenotype with a rabbit with the genotype Bb Gg is black eyes with gray hair.
Question 8: The probability that the offspring will have an offspring who is heterozygous is 100 out of 100.
Question 9: According to the Punnett square, the probability that an offspring would have triangular eyes is 2:4 or 1:2.
Question 10: The genotype of the mother for this sex-linked trait cannot be determined with the given information.
