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
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
b
3/16
c
4/16
d
9/16

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
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.
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?

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
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?
a
AB, Ab, aB, and ab
b
AaBb and ABab
c
Aa, Bb, AA, and bb
d
AB and Ab
Question 1:
To determine the calf that is most likely the offspring of the cow, analyze the DNA fingerprint. Look for similarities and patterns between the cow and each calf's DNA fingerprint. The calf that shares the most similar or matching DNA bands with the cow is likely to be the offspring.
Question 2:
To determine the genotype of the mother for the sex-linked trait of spots in clouded leopards, analyze the information given. Cross a male with dark spots and a female with normal spots. Observe the offspring and their spots. If some offspring have normal spots and some have dark spots, it indicates that the mother is heterozygous for the sex-linked trait.
Question 3:
To calculate the probability of albinism in the offspring of a cross between two rabbits with AaBb alleles, set up a Punnett square. Use the alleles A and a for the first pair and B and b for the second pair. Cross Aa with Bb and determine the combinations of alleles in the offspring. Count the number of combinations that result in the albino genotype (aa) and calculate the probability by dividing the number of occurrences of the albino genotype by the total number of possible genotypes.
Question 4:
To determine the genotype in the bottom right-hand corner (red square) of a dihybrid cross, refer to the given word bank of possible genotypes. Find the genotype that matches the traits being crossed and fill it into the blank space.
Question 5:
To determine if Gerald can be the father of the child with type O blood, create a Punnett square. Use the blood types of LaToya (type A) and Gerald (type B) to determine the possible genotypes of the parents. Cross the genotypes and observe the blood types in the offspring. If the Punnett square shows that type O blood is a possible result, then Gerald can be the father.
Question 6:
To calculate the probability of having an offspring who is heterozygous for the awesome trait in orange tabby cats, use the given information. Determine the genotypes of the male and female cats involved in the mating. Set up a Punnett square and cross the genotypes. Count the number of offspring with the heterozygous genotype and calculate the probability by dividing the number of heterozygous offspring by the total number of offspring.
Question 7:
To select the best advantage associated with the method of reproduction that Julia and Vinay observed, analyze the information given. Based on the images of the cells and the information about the organism producing gametes to create offspring, consider the advantages of this method. Select the advantage that most directly aligns with the information provided.
Question 8:
To calculate the probability of having an offspring who is heterozygous for the awesome trait in orange tabby cats, use the given information. Determine the genotypes of the male and female cats involved in the mating. Set up a Punnett square and cross the genotypes. Count the number of offspring with the heterozygous genotype and calculate the probability by dividing the number of heterozygous offspring by the total number of offspring.
Question 9:
To understand the purpose of a pedigree, analyze the options provided. Determine which statement accurately describes the use of a pedigree in genetics. Select the option that aligns with the definition and purpose of a pedigree.
Question 10:
To determine all the possible combinations of alleles that could be found in the gametes due to independent assortment, analyze the given information. Consider the concept of independent assortment and the presence of two similar pairs of chromosomes in the cell. Select the option that accurately lists all the possible combinations of alleles based on this information.
