An allele is:

Phenotype refers to the ______________________ of an individual.

The idea that different pairs of alleles are passed to offspring independently is Mendel's principle of:

The idea that for any particular trait, the pair of alleles of each parent separate and only one allele from each parent passes to an offspring is Mendel's principle of:

When crossing a homozygous recessive with a heterozygous organism, what is the chance of getting an offspring with the homozygous recessive phenotype?

If a corn plant has a genotype of Ttyy, what are the possible genetic combinations that could be present in a single grain of pollen from this plant?

Two plants are crossed, resulting in offspring with a 3:1 phenotype ratio for a particular trait. This suggests

An example of homozygous genotypes could be LL or ll

An example of a heterozygous genotype would be: Gg 

What does a Punnett square show?

A heterozygous organism has

Factors that control traits are called

If a disease is only carried on the X or Y chromosome it is called

Blood typing is caused by multiple alleles (A,B,o)

Blood type A can be either gentoypes AA or Ao

Blood type B can be either gentoypes BB or Bo

Blood type O can can only be oo

If both A and B alleles are received from an individuals parents then they will have AB blood.
