Types of Inheritance and Blood Typing

Front

What is incomplete dominance?

Back

Incomplete dominance is a genetic situation in which one allele does not completely dominate another allele, resulting in a blended phenotype in the offspring.

Front

What does a Punnett square represent?

Back

A Punnett square is a diagram used to predict the outcome of a genetic cross by showing the possible combinations of alleles from the parents.

Front

What is the probability of having a child with Type A blood if one parent is Type A (genotype AO) and the other is Type O (genotype OO)?

Back

25%.

Front

What is the probability of having a child with Type AB blood if one parent is Type A (genotype AO) and the other is Type B (genotype BO)?

Back

25%.

Front

In complete dominance, if brown eyes are dominant (B) and blue eyes are recessive (b), what are the possible genotypes of a parent with brown eyes?

Back

The possible genotypes are BB (homozygous dominant) or Bb (heterozygous).

Front

What is the definition of a homozygous genotype?

Back

A homozygous genotype consists of two identical alleles for a particular gene, either dominant or recessive.

Front

What is the definition of a heterozygous genotype?

Back

A heterozygous genotype consists of two different alleles for a particular gene, one dominant and one recessive.

Front

What is the phenotypic ratio expected from a monohybrid cross?

Back

The expected phenotypic ratio from a monohybrid cross is typically 3:1.

Front

What is the genotypic ratio expected from a monohybrid cross?

Back

The expected genotypic ratio from a monohybrid cross is typically 1:2:1.

Front

What are the four main blood types in the ABO blood group system?

Back

The four main blood types are A, B, AB, and O.
