Punnett Squares and Complex Inheritance

If B symbolizes black fur and b symbolizes white fur, then what would the genotypes look like if parent 1 is homozygous recessive and parent 2 is heterozygous?

(parent 1 x parent 2)

• hh X Hh

• hh X HH

• Hh X Hh

• Black and white fur

G = green hair

g = pink hair

After doing a monohybrid cross you get the following genotypes: GG, Gg, Gg, GG

What is the probability that the offspring have PINK hair?

• 0%

• 25%

• 50%

• 100%

For the first trait, G = green hair and g = pink hair. For the second trait, Y = yellow eyes and y = white eyes.

After a dihybrid cross you find that 100% of the offspring have the genotype Ggyy.

What is their phenotype?

• Green hair and white eyes

• Pink hair and white eyes

• Green hair and yellow eyes

• Pink hair and yellow eyes

What goes in the missing box "?"

• TT

• tt

• Tt

• None of the above

If a red flower mixed with a white flower to create a pink flower we would call this...

• Complete Dominance

• Codominance

• Incomplete Dominance

• Multiple Alleles

FOIL parent 1 alleles: HhGG

• HG and hG

• HH and GG

• HG and hg

• HG only

What would be in the missing boxes "?"

• Hh for both

• hh for both

• HH for both

• Hh and HH

The AB blood type has both the A proteins from one allele and the B proteins from another. They do not blend. We call this...

• Incomplete Dominance

• Codominance

• Complete Dominance

• Recessive Dominance
