Mendelian Genetics

Front

What is a phenotype?

Back

An observable, physical characteristic of an organism, such as color or height.

Front

What is the probability of offspring showing a recessive trait if the Punnett square shows a 25% chance?

Back

25%.

Front

What does heterozygous dominant mean?

Back

An allele pair consisting of one dominant and one recessive allele, represented as 'Ff'.

Front

What determines genetic traits?

Back

Genes.

Front

What plant did Gregor Mendel use for his famous experiments?

Back

Pea plants.

Front

What is a genotype?

Back

The genetic makeup of an organism, represented by allele combinations.

Front

What is the difference between homozygous and heterozygous?

Back

Homozygous has identical alleles (e.g., 'FF' or 'ff'), while heterozygous has different alleles (e.g., 'Ff').

Front

What is a dominant allele?

Back

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

Front

What is a recessive allele?

Back

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

Front

What is a Punnett square used for?

Back

To predict the genetic outcomes of a cross between two organisms.
