B) an allele that blocks or hides a recessive gene

4. Which of the following is Homozygous?

A) when you got your genes from mum
B) when a person's two alleles for a gene are different
C) when you got your genes from dad
D) when a person's two alleles for a gene are the same

5. Which of the following is Heterozygous?

A) when a person's two alleles for a gene are the same
B) when you got your genes from mum
C) when you got your genes from dad
D) when a person's two alleles for a gene are different

6. Heterozygous genotype for any allele...

A) always results in the recessive characteristic

11. A genotype is

A) A person's set of alleles for a particular trait
