Punnett Square

Front

What is Mendel's Law of Segregation?

Back

Each parent gives 1/2 of their directions/code for each trait to the offspring.

Front

How is the Punnett Square set up?

Back

The genotypes of each parent are on the sides and the offspring is in the boxes.

Front

What must the genotype of the missing parent be if the options are BB, Bb, bb, Tt?

Back

Bb

Front

Which of the following genotypes is homozygous dominant: A, Aa, AA, aa?

Back

AA

Front

Aa, DD, bB, yy are all examples of what?

Back

Genotypes.

Front

What does a Punnett Square illustrate?

Back

The possible genetic combinations of offspring from two parents.

Front

Define genotype.

Back

The genetic makeup of an organism, represented by letters (e.g., AA, Bb).

Front

Define phenotype.

Back

The observable traits or characteristics of an organism, influenced by its genotype.

Front

What is the difference between homozygous and heterozygous genotypes?

Back

Homozygous has identical alleles (e.g., AA or aa), while heterozygous has different alleles (e.g., Aa).

Front

What does it mean if a trait is dominant?

Back

A dominant trait is expressed in the phenotype even if only one allele is present.
