Genetics and Heredity Practice

G = green, g = yellow

The genotype for a yellow plant is...

• GG

• Gg

• gg

• all of the choices result in yellow

B = brown fur b = white fur

In the punnett square, what is the probability for white fur?

• 0%

• 25%

• 50%

• 75%

Two brown eyed parents (Bb) have a baby. What is the chance their baby is blue eyed (bb)? Draw the Punnett square for help

• 0 %

• 25%

• 50%

• 75%

Which of the following genotypes is homozygous dominant?

• aa

• Aa

• AA

AA and Aa always show up as ---

• dominant.

• recessive.

Aa, DD, Ba, and yy are all examples of ---

• genotypes

• phenotypes

Which of the following genotypes is heterozygous?

• Bb

• BB

• bb

Brown eyes are dominant (D) over blue eyes (d). What is the probability that the offspring will have brown eyes in this cross? Complete the Punnett square for help

• 25%

• 50%

• 75%

• 100%

Gregor Mendel is often called ....

• The father of heredity.
• The father of genetics.
• The king of peas
• The father of punnett squares.

What are genes?

• Something you wear.
• Segments of DNA that carry traits for offspring.
• The powerhouse of cells.
• None of the above.
