What is the phenotype of an organism?

Back

Its physical appearance

In pea plants, round is dominant to wrinkled and yellow is dominant to green seed coats. What is the probability of getting both round and yellow seeds in a heterozygous dihybrid cross?

Define Mendelian Genetics.

Back

The study of how traits are inherited through generations based on the principles established by Gregor Mendel.

Front

What is a genotype?

Back

The genetic makeup of an organism, represented by alleles.

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.

Front

What is a dihybrid cross?

Back

A genetic cross that examines the inheritance of two different traits.
