Mendel's Principles of Inheritance

Character & ex.

to a heritable feature that can be observed or measured

Ex. Colour of eyes or colour of hair

\
the physical mafistation of

Trait & ex.

Each variant for character

Ex. Blue eyes or red hair

True-breeding

you can only have an identical offspring with no additional traits/characters

\
\

Hybridization

when 2 parents express the same character but different traits.

\
\

P-generation

The First generation that you start studying

F1 generation

the first offspring of the P-generation

F2 generation

the offspring that comes after the first gen.

Explain the processes by which Mendel conducted his experiments?

1. took two plants with the same charateristic but different traits.
2. cut off one of the male reproductive parts so that he could control whether or not the plant would be pollinated.
3. via a paint brush, he brushed on the pollen on the female reproductive parts of plant b (this was the p-generation)
4. than after he had the F2 generation, he restarted his process for a larger simple size and found that plant A and plant B had a 3:1 ratio with that specific characteristic

\
The first thing Macdonal did was he took two plants which had the same characteristics but different traits, and he cut off the male reproductive parts one of the plants which car which allowed him to control which plan Scott pollinated, and which plants did not.

He then pollinated the ones that he wanted to, and those became the P generation, and as we saw through the F1 generation, it had a different offspring, but then the one that was really important was the F2 generation, which showed the three to one ratio

Explain why Mendel could be sure any offspring produced were by his design?

Because by cutting off the male reproductive part of plant a and plant b he could sure that the pollen from plant a could be put on plant B via a paintbrush

all the plants he was using were true breeding

What proportion did Mendel consistently observe in the F2 generation?

Gregor Mendel continuously saw three to one ratio with his experiments with the purple flowers and white flowers. With the white flowers being significantly less and purple flowers being significantly high.
