Intro to Genetics Quiz (Chapter 12)

Each pea-plant gamete has how many alleles for the height gene?

• 1
• 2
• 3
• 4

Different forms of a gene

• Alleles
• DNA
• RNA
• Nucleus

Managed by Gregor Mendel by removing male parts from the flowers of some plants

• Controlling crosses between plants
• He took joy in harming plants
• Created all female plants
• Made the plants skip to the F2 generation

An organism that has two different alleles for a trait. In general the dominant trait will be expressed in the phenotype.

• Heterozygous
• Homozygous
• Polyzygous
• Trizygous

An organism that has two identical alleles for a trait

• Homozygous
• Heterozygous
• Polyzygous
• Trizygous

Both alleles (factors) for a trait are the same and recessive (aa)

• Homozygous recessive
• Heterozygous recessive
• Homozygous Dominant
• Heter0zygous Dominant

Both alleles (factors) for a trait are the same and dominant (AA)

• Homozygous Dominant
• Homozygous recessive
• Heterozygous recessive
• Heterozygous Dominant

• Genotype
• Phenotype
• Chromotype
• Heterotype

An organism's physical appearance, or visible traits.

• Phenotype
• Genotype
• Chromotype
• Heterotype

Parental generation, the first two individuals that mate in a genetic cross
