Genetics and Meiosis

The genetic makeup of an organism or what represents the letters in a Dihybrid Cross

• allele
• genotype
• phenotype
• karyotype

What describes the physical appearance of a trait?

• allele
• genotype
• phenotype
• karyotype

If alleles look like Aa in a genotype it is said to be

• homozygous
• heterozygous
• incomplete dominant
• codominant 

If alleles look like AA in a genotype it is said to be

• homozygous
• heterozygous
• incomplete dominant
• codominant

Trait will always show up in an organism if the allele is present

• recessive
• dominant
• incomplete dominant
• codominant

This all is covered up when a dominant allele is present

• recessive
• dominant
• incomplete dominance
• co-dominant

What shows the possible combinations of alleles that can result from a genetic cross?

• bar graph
• pie chart
• punnett square
• co-dominant graph

If two heterozygous tall plants are crossed, and tall is dominant. What would be your expected phenotypes?

• 100% tall
• 75% tall, 25%short
• 50% tall, 50%short
• 25% tall, 75% short

What is going to be the genotype that is missing?

• AABb
• AABB
• AAbb
• aaBB

Which produces the greatest amount of genetic variation?

• Sexual reproduction with few mutations
• Sexual reproduction with many mutations
• Asexual reproduction with few mutations
• Asexual reproduction with many mutations
