Mendel's Laws and Monohybrids

An allele is

• another word for a gene
• a homozygous genotype
• a heterozygous genotype
• one of several possible forms of a gene

What does heterozygous mean?

• An organism that has the same alleles for a trait (TT or tt)
• An organism that has different alleles for a trait (Tt)
• When neither allele is fully dominant; offspring is a mixture of both
• the different forms of a trait (hair color--> brown, blonde, red

If your genotype is Bb, then you can only pass a B or b to your child but you can't pass both.

• Law of Dominance

• Law of Segregation

• Law of Independent Assortment

Person A is smart and has brown hair while Person B is also smart but has blonde hair.

• Law of Dominance

• Law of Segregation

• Law of Independent Assortment

One gene for the type of earlobes a person will have will be in each gamete.

Which of Mendel's laws states that alleles are distributed to gametes independent of one another?

• Law of Dominance

• Law of Segregation

• Law of Independent Assortment

genotype

• the allele combination of an organism

• different forms of genes

• alleles for traits are the same

• factors that determine traits

phenotype

• factors that determine traits

• every organism has two alleles which separate when gametes are produced

• genes for different traits are inherited independently of each other

• the way an organism looks and behaves

Round seeds (R) are dominant over wrinkled seeds (r). What percentage of the offspring will be round from the following cross?
Rr X Rr

• 100%
• 75%
• 50%
• 25%
