Cow Mom I Love Moo Mug: Kitchen & Dining
a. Calf 1
b. Calf 2
c. Calf 3
Selected:d. Calf 4
Question 2
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. homozygous
b. impossible to determine with given information
Selected:c. heterozygous
d. purebred for normal spots
Question 3
Take out a piece of paper and pencil to solve the Dihybrid cross.
Rabbits have two unlinked allele pairs that affect fur color. The table shows how allele pairs affect fur color. The term “agouti” describes fur with pigmentation that gives the fur a banded appearance.
Rabbits with the aa allele pair are albino, regardless of the second allele-pair combination.
What is the probability of albinism in the offspring of a cross between two rabbits with AaBb alleles?
a. 1/16
Selected:b. 3/16
c. 4/16
d. 9/16
Question 4

What is the genotype expected in the bottom right-hand corner (red square) _
Review is dihybrid cross:
What is the genotype expected in the bottom right-hand corner (red square) ggbb
Question 5
LaToya has type A blood, and Gerald has type B blood. Their daughter has type O blood. Can Gerald be the baby daddy? He is a bit worried.
Please complete the Punnett square(s) to determine the possibilities.
a. Yes, if one parent is heterozygous
b. Yes, if both parents are heterozygous
Selected:c. No, this is impossible
d. No, type B blood must be homozygous
Question 6
Premium Photo | Three little orange striped kitten on white background high resolution photoA 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.
What is the probability that they will have an offspring who is heterozygous? _ out of _

Question 7
Julia and Vinay are learning about cells in their high school Biology class. To gain a deeper understanding of cells, their teacher is having them perform a laboratory experiment to identify unknown cell types. Julia and Vinay must create a hypothesis based on the cell types they believe they will identify. Then they will be given three microscope slides that contain samples of different cell types. During the experiment, Julia and Vinay will answer analysis questions, and after the experiment, they will complete a laboratory report with a conclusion.
After Julia and Vinay got their microscope slides, they set them up on their microscope. The images show the three cell types Julia and Vinay viewed while looking under their microscope.
Sample X
Sample Y
Sample Z
Julia and Vinay both agree that the cells found in Sample Y come from an animal. They infer that the organism the cells were extracted from produces gametes to create offspring. Select the best advantage associated with this method of reproduction that Julia and Vinay could list in their laboratory notebook.
a. It only requires one parent.
b. It can quickly increase a population.
c. Genetically identical offspring are produced.
Selected:d. There is genetic variation among the offspring.
Question 8
Premium Photo | Three little orange striped kitten on white background high resolution photoA 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?

4 out of 4
Question 9
A pedigree can be used to
a. determinie whether a trait is inherited.
b. show how a trait is passed from one generation to the next.
c. determine whether an allele is dominant or recessive
Selected:d. all of the above
Question 10
The diagram shows a cell with two similar pairs of chromosomes.
Due to independent assortment, what are all the possible combinations of alleles that could be found in the gametes?
Selected:a. AB, Ab, aB, and ab
b. AaBb and ABab
c. Aa, Bb, AA, and bb
d. AB and Ab
