How are traits determined?

• Phenotype

• Genotype

• Father sperm

• Alleles

Can you tell someone's genotype just by looking at them?

• Yes the trait is dominant.

• No the trait is homologous.

• No the trait is recessive.

• Yes the trait is haploid.

How many chromosomes are received from parents?

• 23 chromosomes

• 32 chromosomes

• 64 chromosomes

• 46 chromosomes

Principle of Independent Assortment

• Inheritance of one trait has no effect on the inheritance of another trait.

• Inheritance of two traits has no effect on the inheritance of another trait.

• Inheritance of one trait has an effect on the inheritance of another trait.

• Inheritance of one trait has an effect on the inheritance of another trait.

How do we have two copies of each gene?

• Alleles

• We get one from our mother and one from our father.

• We get two from our father and one from our mother.

• We get two from our mother and one from our father.

Is having blue eyes a phenotype or genotype?

• Phenotype

• Genotype

A gene that prevents the other gene from showing is called?

• Recessive

• Dominant

• Allele

• Genotype

What is genetics?

• study of how cells are made

• study of how parents have offsprings

• study of how traits are passed from parent to offspring

• study of physical traits are passed from offspring to parent

A gene that does not show even though it is present?
