Assume that there are two types of pea plants: one with smooth seeds (dominant) and the other with wrinkled seeds (recessive) in a garden. A gardener decides to cross a smooth-seeded plant with a wrinkled-seeded plant to study how the seed texture trait is inherited.

1. Show the appearance of:
a. F1 progeny
b. F2 progeny
when a pure (homozygous) tall pea plant is crossed with a pure (homozygous) short pea plant.

2. A farmer crossed hornless and horned cattle. Hornless (H) in cattle is dominant over horned (h). A homozygous hornless bull is mated with a homozygous horned cow. Show the cross.

3. A farmer crossed red fruit and yellow fruit in tomatoes. Red fruit (R) is dominant over yellow fruit (r). A plant that is homozygous for red fruit is crossed with a plant that has yellow fruit. Show the cross.

4. Brown eyes in humans are dominant to blue eyes. A brown-eyed man, whose mother is blue-eyed, marries a brown-eyed woman whose father had blue eyes. Show the cross.

5. A pea plant that is pure for purple flowers mates with a pea plant that has white flowers. One of their offspring self-fertilizes and produces 100 offspring. How many would you predict to have purple flowers and how many would you predict to have white flowers? Show the cross.

While solving these problems, you should:

1. Create a Punnett square.
2. List the phenotypes and genotypes of the parent plants being crossed.
3. Determine the genotype of the gametes (haploid cells resulting from meiotic division).
4. Find all possible combinations of gametes, as fertilization is a random process.
5. Determine the parental, F1, and F2 generations.
6. Determine the phenotypic and genotypic ratios of the resulting offspring.
