Genetics Middle School

Which of the following is true about Mendel?

• His ideas about genetics apply equally to plants and animals.

• He believed that genetic traits of parents will usually blend in their children.

• His discoveries concerning genetic inheritance were generally accepted by the scientific community when he published them during the mid 19th century.

Mendel believed that the characteristics of pea plants are determined by the:

• inheritance of units or factors from both parents

• relative health of the parent plants at the time of pollination

• inheritance of units or factors from one parent

• a mixing of thing

What were the parents in the P1 generation in Mendel's experiments? Click all that apply.
