Mendel ans his peas

Question 1

Who was Gregor Mendl?

Answer 1

An Austrian monk who did research using peas to investigate herdity (peas: easy to breed/care for, lots of offspring)

Question 2

What is Mendls “nickname”

Answer 2

father of genetics

Question 3

How did Mendl do it?

Answer 3

pea plants have both male & female parts on the same flower (normally: self pollination) cut away male parts before flower matured; enableing him pollination (using a brush)

Question 4

What does dominant mean?

Answer 4

covers the recessive trait, is stronger, capital letter e.g. Y

Question 5

recessive

Answer 5

present but not visible, weaker, lower case letter e.g. y

Question 6

homozygous

Answer 6

(purebread) both alleles are the same e.g. YY or yy

Question 7

heterozygous

Answer 7

(hybrid) alleles are different e.g. Yy, Bb

Question 8

Phenotype

Answer 8

physical appearance of organism

Question 9

Genotype

Answer 9

Yy or YY, the genetic letter representing genes of organsim

Question 10

Whats Mendls first law?

Answer 10

The law of dominance and uniformity:
some alleles are dominant, others recessive: an organsim with at least one dominant gene will display the effect of the dominant allele
F1 generation will be identical/ uniform

Question 11

Mendls second law

Answer 11

the law of segregation
parent organism gives one allele to each gamete; meaning they seperate their genes, giving each gamete only one copy

Question 12

Mendls third law

Answer 12

the law of independant assortment
genes of different traits can segregate independently during the formation of gametes

Question 13

What is intermediate inherance?

Answer 13

inheritance w/o a dominant allele, results in a mix of the two recessive traits
