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

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

Unattached earlobes (E) is dominant. Attached earlobes (e) is recessive. A woman with the genotype (Ee) and a man with the genotype (ee) have a child. What is the probability that the child is heterozygous?

• 0%
• 25%
• 50%
• 75%

 Cell created at the end of meiosis are best known as

• somatic cells
• gamete cells
• skin cells
• diploid cells
