Basic terminologies and ideas

Question 1

Continuous Trait

Answer 1

• A large variety of the trait
• controlled by many genes and are affected by large number of alleles
• The range of values create a bell curve on a graph and can appear as blend and unbend appearance
  -Ex height

“The more genes, the more phenotypic classes and more classes, the more the variation appears continuous”

Question 2

Discrete Traits

Answer 2

either or traits

Question 3

What is the relationship between genotype and phenotype?

Answer 3

Genotype and environmental influences impacts phenotype

Question 4

True breeding

Answer 4

organisms that are homozygous for genes.

Question 5

Progeny

Answer 5

offspring

Question 6

Genes

Answer 6

units of inheritance

Question 7

alleles

Answer 7

alternative form of a single gene

Question 8

Monohybrids

Answer 8

individuals that differ for a single trait

Question 9

Law of segregation

Answer 9

two alleles separate during gamete formation and one from each parent unite at random at fertilization.

Question 10

Law of independent assortment

Answer 10

random (or independent) distribution of different alleles during gamete formation

Question 11

Addition Rule (The ‘or’ rule)

Answer 11

P (A or B) = P(A) + P(B)

Question 12

Multiplication Rule (The ‘and’ rule)

Answer 12

P (A and B) = P(A) x P(B)
