Mendel's Laws Quick Review

Front

Law which states that different traits are inherited independently of each other

Back

Law of independent assortment

Front

If your genotype is Bb, what can you pass to your child?

Back

You can pass either a B or a b, but not both. This illustrates the Law of Segregation.

Front

What does heterozygous mean?

Back

An organism that has different alleles for a trait (Tt).

Front

What does Mendel's Law of Segregation state?

Back

Every person has two alleles for each trait, they segregate from each other and are passed down at random.

Front

Which of the following genotypes is homozygous recessive? Tt, tt, TT, T

Back

tt

Front

What is the definition of homozygous?

Back

An organism that has two identical alleles for a trait (TT or tt).

Front

What is the definition of dominant allele?

Back

An allele that expresses its trait even in the presence of a recessive allele.

Front

What is the definition of recessive allele?

Back

An allele that only expresses its trait when two copies are present (tt).

Front

What does Mendel's Law of Dominance state?

Back

In a heterozygous genotype, the dominant allele will mask the effect of the recessive allele.

Front

What is a genotype?

Back

The genetic makeup of an organism, represented by alleles (e.g., Bb, TT).
