Question

Mendel crossed tall pea plants with short pea plants. The offspring were all tall plants.

Answer 1

Answer:

The short is recessive and the tall is dominant

Explanation:

The Punnett Square would look like this (T - tall, t - short):

  |  T |  T  |

t | Tt | Tt |

t | Tt | Tt |

All offspring carry the short gene, but the tall gene is dominant, so the plants are tall with the possibility of having short offspring of their own.

Answer 2

Recessive: Short

Dominant: Tall
