Medelian Inheritance

In a cross between a homozygous dominant parent and a heterozygous parent, what is the chance of the offspring having a dominant phenotype?

100%

In a cross between a homozygous dominant parent and a homozygous recessive parent, what is the chance of the offspring having a dominant phenotype?

100%

In a cross between a homozygous dominant parent and a homozygous recessive parent, what is the chance of the offspring having a heterozygous genotype?

100%

In a cross between a homozygous dominant parent and a heterozygous parent, what is the chance of the offspring having a heterozygous genotype?

50%

In a cross involving two heterozygous parents, what is the chance of the offspring having the dominant phenotype?

75%

used to determine the expected percents of different genotypes in offspring

Punnett square

What is the inheritance pattern when the dominant allele is not completely dominant?

incomplete dominance

it occurs when the dominant allele is not completely dominant

incomplete dominance

cell division involved in gamete formation

meiosis

What is the inheritance pattern associated with the ABO blood type in humans?

multiple alleles

it is closely associated with appearance

phenotype

it is controlled by more than one gene

polygenic characteristic

a chance that a certain event will occur

probability

an example of a characteristic due to multiple alleles

ABO blood type

an alternative form of a gene

allele

What is the inheritance pattern when both alleles are expressed equally in the phenotype of a heterozygote?

codominance

occurs when both alleles are expressed equally in the phenotype of the heterozygote

codominance

the expressed allele in a heterozygote

dominant allele
