Section 2: Mendel's Laws of Heredity Quiz

What are the factors that determine traits called?

• Phenotype

• Genes

• Alleles

• Genotype

What are different forms of genes called?

• Genes

• Alleles

• Genotype

• Phenotype

What is the Law of Segregation?

• An organism is homozygous for a trait if its two alleles for the trait are different

• Genes for height can either produce genes for tall plants or genes for short plants

• Every organism has two alleles of each gene and when gametes are produced the alleles separate

• Genes for different traits are inherited independently of each other

What is the phenotype of an organism?

• Genes for different traits are inherited independently of each other

• Every organism has two alleles of each gene and when gametes are produced the alleles separate

• The allele combination of an organism (TT, tt, Tt)

• The way an organism looks and behaves (tall or short)

What is the genotype of an organism?

• The way an organism looks and behaves (tall or short)

• The allele combination of an organism (TT, tt, Tt)

• Every organism has two alleles of each gene and when gametes are produced the alleles separate

• Genes for different traits are inherited independently of each other

What does it mean if an organism is homozygous for a trait?

• The allele combination of an organism (TT, tt, Tt)

• The way an organism looks and behaves (tall or short)

• An organism is heterozygous for a trait if its two alleles for the trait are different

• An organism is homozygous for a trait if the two alleles for the trait are the same

What does it mean if an organism is heterozygous for a trait?

• The allele combination of an organism (TT, tt, Tt)

• The way an organism looks and behaves (tall or short)

• An organism is heterozygous for a trait if its two alleles for the trait are different

• An organism is homozygous for a trait if the two alleles for the trait are the same

What is the Law of Independent Assortment?

• Genes for height can either produce genes for tall plants or genes for short plants

• An organism is homozygous for a trait if its two alleles for the trait are the same

• Genes for different traits are inherited independently of each other

• Every organism has two alleles of each gene and when gametes are produced the alleles separate

What can be observed in a dihybrid cross?

• Genes for height can either produce genes for tall plants or genes for short plants

• Every organism has two alleles of each gene and when gametes are produced the alleles separate

• Genes for different traits are inherited independently of each other

• Both of Mendel's laws at work

What is an example of a two alleles that are homozygous dominant?

• TT

• Tt

• tt

• tT
