Mendell Genetic (Chap 11)

Question 1

Genotype vs. Phenotype

Answer 1

-genes (genetic makeup), control hereditary traits
vs
- structural + functional. determined by interaction with environment

Question 2

Mendel’s exp design

Answer 2

• tested: seed coat/flower color, seed color, seed shape, pod color, stem height, flower, position, pod shape
• used self fertilizing Pitsum sativum
• cross-fert and true-breeding

Question 3

Monohybrid crosses

Answer 3

• Pgeneration (P) and first filial gen. (F)
• reciprocal crosses
• 1-trait inheritance

Question 4

Mendel’s Principal of Segregation

Answer 4

1-reciprocal cross= results sim
2- F resembles P : therefor allele dominant
3-F2 reveal P trait= home reces

Question 5

Wild type allele

Answer 5

• loss-of-function mutation= decreases functionality

- null mutation: no change

Question 6

Dihybrid Crosses+ Mendel’s Principe of Independent Assortment

Answer 6

• dif allel on dif chromo segregate independently–> gamete

- all combo of factors can occur in gamete

Question 7

phenotypic rule

Answer 7

2^n, n=gamete

Question 8

rule of multiplication

Answer 8

change of two+ ind, events occurring together equals the chances of occurring separately
