When you need to determine if an organism is homozygous or heterozygous, you need to cross it with a recessive organism and look at the offspring. Why?

The different forms of a gene are called...

13) A homozygous round seeded plant is crossed with a homozygous wrinkled seeded plant. a. What are the genotypes of the parents?

11) A Tt plant is crossed with a Tt plant. What percentage of the offspring will be short

12) A heterozygous round seeded plant (Rr) is crossed with a homozygous round seeded plant (RR). What percentage of the offspring will be homozygous round?

Long stalks in some plants are dominant to short stalks. Using the letter "L", what are the possible genotypes of a heterozygous mother and a recessive father?

If an organism shows the recessive trait, is it heterozygous or homozygous?

Recessive alleles are represented by what type of letter?

On a Punnett Square, each box represents what percentage?

The study of genetics is called...

Dominant alleles are represented by what type of letter?

Give an example of the three (3) options of the genotypes using the letter "T"

On a Punnett Square, the parents are located on....
