Genetics Test Review Part 2

Organisms that have two identical alleles for one gene are said to be

• Hybrid
• Homozygous
• Heterozygous
• Dominant

Gametes are which of the following

• Sperm Cell
• Egg Cell
• Sex Cells
• All of the above

Based on the Punnett square in Figure 1, which of the following is correct if brown is dominant over green?

(B = Brown, b = green)

• mother=brown eyes; father=green eyes

• mother =brown eyes; father=brown eyes

• mother=green eyes; father=green eyes

• mother=green eyes; father=brown eyes

What does a Punnett Square show?

• All of Mendel's discoveries about Genetics
• Only recessive alleles in a genetic cross
• All the possible outcomes of a genetic cross
• Only the dominant alleles in a genetic cross
