Genetics Vocabulary

Multiple alleles means

• more than two alleles exist for a trait

• more than one set of genes controlling a trait

• multiple traits controlled by one set of genes

• phenotypes of dominant alleles blend to form a third phenotype

Some cattle have red hairs, some have white. Roan cattle have red and white. What type of inheritance is this?

• dominance

• incomplete dominance

• codominance

• multiple alleles

Polygenic means

• more than one allele for a trait

• more than one set of genes controlling a trait

• multiple traits controlled by one set of genes

• phenotypes of dominant alleles blend to form a third phenotype

The genetic make-up, or set of alleles for an organism.

• genotype
• phenotype
• chromosome
• alleles

How are Incomplete Dominance and Co-Dominance different than a normal Mendelian cross?

• There is no difference

• The heterozygous genotype has a unique phenotype

• There is no heterozygous genotype

• There is only one phenotype regardless of genotype.

What type of inheritance do two alleles have if their traits blend together? 

• Incomplete Dominance
• Co-Dominance
• Mendelian Inheritance
• Homozygous Inheritance

Physical traits of an organism determined by its genotype.

• genotype
• phenotype
• alleles
• gene pair

An allele whose trait only shows up when no dominant allele is present.

• hidden allele
• dominant allele
• recessive allele
• present allele

This type of inheritance pattern is a MIXTURE of both traits.

• incomplete dominance
• co-dominance
• complete dominance
• recessive pattern
