Mendel

Question 1

Who is Mendel?

Answer 1

Founding father of genetics

Question 2

What concept did he use?

Answer 2

Pea plants and genetics

Question 3

Explanation of the pea plants

Answer 3

Mendel compiled a yellow seeded plant with a green seeded plant and he got only yellow seeds
He called the yellow colour trait the dominant one because it was expressed in all the new seeds
Then he let the new yellow seeded hybrid plants self fertilise, and in the second generation, he got both yellow and green seeds meaning the green trait had been hidden by the dominant yellow. He called this hidden trait the recessive trait

Question 6

Define : Heterozygous

Where the two alleles are different

Question 7

Define : Genotype

Answer 7

Unique sequence of DNA (eg. AAB)
