Multiple Choice

According to Mendel's law of dominance, some alleles are dominant over others. How many copies of each gene does an organism receive?

• One copy

• Four copies

• Two copies

• Three copies

Multiple Choice

What does the law of segregation state?

• An organism should get two copies of each gene

• Genes are located on chromosomes

• An organism should only donate one copy of their genes to their gametes

• Genes for different traits can segregate independently during the formation of gametes

Multiple Choice

What does the law of independent assortment state?

• Genes for different traits can segregate independently during the formation of gametes

• Some alleles are dominant over others

• Genes are located on chromosomes

• An organism should get two copies of each gene

Open Ended

What does the chromosome theory of inheritance state?

Multiple Choice

What is incomplete dominance?

• When genes are physically located on the same chromosome

• a form of Gene interaction in which both alleles of a gene at a locus are partially expressed, often resulting in an intermediate or different phenotype

• When the heterozygous phenotype is somewhere between the two homozygous phenotypes

• When both traits are fully and separately expressed

Multiple Choice

What is codominance?

• When both traits are fully and separately expressed

• two versions (alleles) of the same gene are expressed separately to yield different traits in an individual.

• When multiple alleles determine a trait when both traits are fully and separately expressed

• When genes are physically located on the same chromosome

Multiple Choice

What is an example of multiple alleles?

• Height

• Personality

• Blood type

Multiple Choice

What is an example of polygenic inheritance?

• Eye color

• Height

• Blood type

Multiple Choice

What are linked genes?

• inherited together because they are physically close to one another on the same chromosome

• Genes that determine gender

• Genes that are codominant

• Genes that have multiple alleles

Multiple Choice

What are sex-linked traits?

• Sex-linked traits are traits controlled by their presence on the X or Y chromosome

• Genes that have multiple alleles

• Genes that are physically located on the same chromosome

• Genes that determine gender

Multiple Choice

Unlike autosomes, sex chromosomes in humans are...

• The only chromosomes that determine your phenotypic traits.
• Typically not found on any karyotypes.
• the 45th and 46th chromosome on a karyotype.
• also known as a di-zygote.

Multiple Choice

The process of evolution involves changes in the genetic makeup of a population over a period of time. Sexual reproduction enhances variability among offspring. The random alteration of DNA from parent to offspring, called mutations, also produces variable characteristics in offspring. Some mutations can be helpful, while others can be harmful and hinder survival. In this experiment, students mimicked random mutations. Data was collected to determine if the mutations were helpful or harmful when trying to collect and eat food. Which mutation provided an advantage for food collecting, but was detrimental when it came to food eating?

• Group D hands fused
• Group B paddle hands
• Group E webbing on hands and feet
• Group A long nails

Multiple Choice

There are alleles for red hair and white hair in cattle. Roan cattle specifically show codominance for the color of their hair. What would you expect a heterozygous roan bull to look like if the trait showed incomplete dominance instead?

• It would be white.
• It would be spotted.
• It would be pink.
• It would be red.

Multiple Choice

A breed of chicken shows codominance for feather color. One allele codes for black feathers, another codes for white feathers. The feathers of heterozygous chickens of this breed will be...

• speckled
• gray
• white
• black
