lecture 8: implications of mendelian genetics

Question 1

chromosome theory of inheritance

Answer 1

1. chromosomes come in pairs (2n)
2. homologous chromosomes separate during meiosis so that alleles are segregated
3. meiotic products (gametes) have one of each homologous chromosome, but not both
4. fertilization restores the pairs of chromosomes to the diploid number (2n)
5. gene loci are found on chromosomes

Question 2

probabilites rang from

Answer 2

0.0 to 1.0

Question 3

product law

Answer 3

calculates the probability of tow or more events occuring simultaneously

Question 4

sum law

Answer 4

calculates the probabilty that possible outcomes of two events are independent of one another, but can be accomplished in more than one way

Question 5

mendels ratios are predictions based on:

Answer 5

• each allele is dominant or recessive
• segretation is unimpeded (anaphase)
• independent assortment occurs
• fertilization is random

Question 6

degrees of freedom (df)

Answer 6

n-1
* number of different categories into which the data are divided

Question 7

p < 0.05

Answer 7

reject null
