Choose the statement that correctly describes the forms alleles may take on a chromosome.

Read the description for common traits in the data table.

Determine your phenotype and possible genotype. Heterozygous alleles make it impossible to know your exact genotype for a dominant trait.
Type your answers into the following input field(s). Type the phenotype then add a comma followed by the genotype. Your answer should look like this: phenotype, genotype

Facial Dimples

Bent little finger

Eye Color

Genetics Predicting Traits

Use the allele/gene choices in the word bank to create a Punnett square for a cross of sheep heterozygous for the dominant trait white wool (Ww X Ww). Word bank choices may be used more than once.

Select the correct allele/gene choice for each box of the Punnett square.

1. 
The caterpillars of monarch butterflies eat milkweed leaves. Milkweed leaves contain sap that is toxic to many animals but not to monarch butterfly caterpillars. This sap makes the monarch butterfly caterpillars toxic to predators and protects them from being eaten. Which of these is an inherited trait of monarch butterfly caterpillars?

2. 
Certain species of whiptail lizards have only female individuals and no males. These lizards reproduce asexually. What is one disadvantage of asexual reproduction for these lizards?

3. 
Three cousins have a similar appearance but different face shapes. Which of these cell components are most involved in determining the basic shape of each girls face?

4. 
Mitosis is responsible for the growth and replacement of somatic (body) cells. The end result of mitosis is ______

5. 
What process and type of resulting cells is represented in the diagram above?

6. 
Wheat was one of the first plant crops that humans domesticated. In the process of domestication, the wild form of wheat was eventually changed into a form more suited to human agricultural practice. Early farmers most likely used seeds only from wheat plants with ____

7. 
Tomato plants usually have hairy stems. Hairless stems are present in tomato plants that are homozygous recessive for this trait. If the stem characteristics are determined by a single gene, what is the expected outcome of crossing two tomato plants that are heterozygous for hairy stems?

8. 
Albinism is a recessive condition. Which circle graph shows the genotype probability when an albino female mates with a male that is heterozygous for the albinism trait?

9. 
A mutation that occurs in the gametes of an organism will most likely be transferred to which of the following?

A group of students made the observations listed below about the size, shape, and appearance of their hands. Which of the students’ observations describe inherited traits?

2. 
The hydra is a very small, simple animal that lives in water. Hydras reproduce asexually by budding, a process in which a bud breaks off an adult hydra and floats away. Which of the following best describes a hydra bud?

3. 
A tiger cub has a pattern of stripes on its fur that is similar to that of its parents. Where are the instructions stored that provide information for a tiger’s fur pattern?

4. 
Sexual reproduction in animals depends on the production of gametes (egg and sperm cells). Which of these processes produces gametes in animals?

Some dairy farmers want to increase the amount of milk produced by their cows. How can the farmers use selective breeding to increase milk production?

9. 
During the final stages of human gestation, receptors for the hormone oxytocin increase on the smooth muscle cells of the uterus. The release of oxytocin during labor stimulates the smooth muscle tissue in the wall of the uterus. The strong contraction of the smooth muscle in the uterus helps push the baby through the birth canal so that delivery can occur. Mutations can have ______
