What did the difference in the F1 and F2 offspring show Mendel?
What did the differences in the F1 and F2 offspring show Mendel? In all of Mendel’s crosses only one form of the trait appeared in the F1 generation. However, in the F2 generation, the “lost” form of the trait is always reappeared in about one fourth of the plants.

When you think of the traits of the parent plants, why is this result surprising? | When you think of the traits of the parent plants, why is this result surprising? |
What trait’s did the plants in the F1 generation of Mendel’s experiment exhibit?
When the F1 plants in Mendel’s experiment were self-crossed, the F2 offspring exhibited the dominant trait or the recessive trait in a 3:1 ratio, confirming that the recessive trait had been transmitted faithfully from the original P parent.
What trait or traits did the plants in the F1 generation exhibit when you think of the traits of the parent plants Why is this result surprising?
What trait or traits did the plants in the F1 generation exhibit? When you think of the traits of the parent plants, why is the result surprising? F1 were tall plants. This was surprising because one was tall and one was short, but the offspring were all tall.
What trait in pea plants is being studied in the cross above?
What trait in pea plants is being studied in the cross shown above? The trait that is being studied is the height of the pea plants.
Which of the following contrasting traits are dominant for pea seed?
Note:According to the Mendel’s study the dominant traits of pea plants are round seed shape, yellow seed colour, violet flower colour, inflated pod shape, green pod colour, axial flower position, and tall stem height.
How many contrasting traits of pea were studied by Mendel?
After they have planted and grown five plants, Mendel asks students how many distinguishing traits they see in the plants. On the next screen, he reveals that there are seven different traits: Pea shape (round or wrinkled) Pea color (green or yellow)
What are the seven traits of a pea plant?
On the next screen, he reveals that there are seven different traits:
- Pea shape (round or wrinkled)
- Pea color (green or yellow)
- Pod shape (constricted or inflated)
- Pod color (green or yellow)
- Flower color (purple or white)
- Plant size (tall or dwarf)
- Position of flowers (axial or terminal)
What is the offspring of many generations that have the same traits?
Purebred – The offspring of many generations that have the same traits.
