This diagram represents what type of inheritance pattern?

• sex-linked inheritance
• complete dominance
• codominance
• incomplete dominance

There are many variations in skin color that can be inherited based on the combination of alleles (more than one gene) that you inherit from your mom and dad. This bell curve distribution is an example of

• incomplete dominance

• codominance

• multiple alleles

• polygenic inheritance

If this image were real, it would represent what type of inheritance? Hint: half black, half white

• incomplete dominance

• codominance

• polygenic inheritance

• compete dominance

If a red biobug and a white biobug mate, their babies have red and white spots.  This is most likely due to what pattern of inheritance?

• incomplete dominance
• codominance
• polygenic inheritance
• compete dominance

Colorblindness is a trait that is seen more often in males and is passed to them by their mothers, who may not be colorblind. Colorblindness is...

• a codominant trait

• a sex-linked trait

• carried on the Y chromosome

• associated with a dominant allele

How much of your DNA do you inherit from your mom?

• 10%
• 25%
• 50%
• it varies

If a gene is found only on the X chromosome and not the Y chromosome, it is said to be what?

• sex-linked trait
• polygenic trait
• codominant trait
• incomplete dominance trait

The X and Y chromosomes are called the

• extra chromosomes.
• phenotypes.
• sex chromosomes.
• All of the answers are correct.

female : XX ::

• female : gametes
• female : eggs
• male : YY
• male : XY

A diagram in which several generations of a family and the occurrence of certain genetic characteristics are shown is called a

• Punnett square.
• monohybrid cross.
• pedigree.
• family karyotype.
