Q

Alleles

A

Alternate versions of genes

Account for variation

Written and expressed as letters (dominant is upper case, recessive is lower)

11
Q

Dominant vs recessive alleles

A

Mask recessive alleles (masks phenotype)

If an individual has both, only the dominant is seen.

Recessive allele for which the phenotype is only seen in the homozygote (pp)

Q

Incomplete dominance

A

Type of inheritance when two alleles blend to form an intermediate phenotype

17
Q

Sex-linked

A

Type of inheritance when the gene is carried on X chromosome but not Y chromosome

18
Q

Carrier

A

General term for a person who is heterozygous for a recessive gene that causes a particular disorder

19
Q

Dominant/recessive

A

Type of inheritance in which one allele masks the phenotype of the other allele
