DOL Topic 1 Lesson 1 Patterns of Inheritance

If two alleles are the same for a certain trait they are considered

• Homozygous

• Twins

• Heterozygous

• Common

Physical traits that are expressed are known as ____________

• Mutation

• Personality

• Genotype

• Phenotype

The different forms of a gene

• heredity
• genetics
• gene
• alleles

This trait always shows up in an organism when the allele is present

• dominant allele
• codominance
• probability
• recessive allele

This trait is hidden whenever the dominant allele is present

• dominant allele
• codominance
• recessive allele
• Punnett Square

A chart that shows all the possible combinations of alleles that can result from a genetic cross

• dominant allele
• codominance
• probability
• Punnett Square

An organism's physical appearance or visible traits

• fertilization
• genotype
• phenotype
• homozygous

An organism's genetic makeup, or allele combination

• fertilization
• genotype
• phenotype
• heterozygous

An organism that has two different alleles for a trait (hybrid)

• fertilization
• genotype
• homozygous
• heterozygous

An organism that has two identical alleles for a trait (purebred)

• genotype
• phenotype
• homozygous
• heterozygous
