Can YOU curl your tongue up on the sides?

Scientists Debunk Familiar Tongue-Rolling Lore | HuffPost Impact

We are pretending that tongue-curling in humans is a dominant genetic trait.

Suppose a man who is Tt for tongue-curling marries a woman who is also Tt for this trait. What are the possible genotypes and phenotypes of their children, and the percent chance for each?

Question 23

In some chickens, feather color is controlled by incomplete dominance. When a black chicken mates with a white chicken, all the offspring are covered in gray feathers.

A farmer mates a black chicken (BB) with a gray (BW) chicken.

What are the predicted phenotypes of their offspring?

a
50% black and 50% gray
 b
75% black and 25% white
 c
100% white
 d
100% gray
Question 24
The variation seen in human skin color and height is an example of a(n)

a
polygenic inheritance.
 b
multiple alleles.
 c
intermediate inheritance.
 d
codominance.
Question 25
Baldness is a dominant trait that is influenced by an individual's sex. A man will become bald if he has the genotype BB or Bb. A man who is bb will not become bald. A woman will have thinning hair, but not become totally bald, if she is BB. A woman will not become bald, or have thinning hair, if she is Bb or bb.

What will be the outcome if a woman who is XXbb produces a child with a man who is XYBb?

a
There is a 75% chance that the child will not become bald.
 b
There is a 25% chance that the child will not become bald.
 c
There is a 100% chance that the child will become bald.
 d
There is a 50% chance that the child will become bald.
Question 26
Which of the following is a disadvantage of asexual reproduction?

a
All organisms have genetic variation
 b
Finding a mate is not needed
 c
Parents produces identical off spring which is not suitable for survival in a changing environment
 d
It can produce a lot of offspring
Question 27
Read the passage about stem cells.

Present in all kinds of tissues, stem cells have the unique ability to develop into other kinds of cells if necessary. An organism's stem cells can transform into brain cells, blood cells, muscle cells, or any other specialized cell found in the organism. Planarian worms have an extremely high stem cell count throughout their bodies.

Which answer best describes an advantage to a planarian worm from having a high stem cell count?

a
a planarian worm's cells can never truly die
 b
planarian worms can adapt to any environmental changes
 c
planarian worms are able to evolve faster than other organisms
 d
a whole new planarian worm can grow from a tiny piece of another
Question 28
What Viruses and Bacteria Have in Common?
Although viruses and bacteria are different, they do share several similarities. Some characteristics common both in viruses and bacteria are explained below:

: Both viruses and bacteria are very tiny and are not seen by naked eyes. Both are found in different forms and can be observed under a microscope.
  :  Viruses and bacteria can infect a host organism (plant, animal, human or a bacterium) and may cause illness.
  : Bacteria and viruses contain a genome.
