Answer 2

an individual heterozygous at two genes

Question 3

independently assorting dihybrid cross expected ratio

Answer 3

9:3:3:1
(A/a;B/b) selfed

Question 4

independently assorting dihybrid test cross expected ratio

Answer 4

1:1:1:1
(A/a;B/b x a/a;b/b)

Question 5

mendel’s second law

Answer 5

law of independent assortment
unlinked or distantly linked segregating gene pairs assort independently assort

Question 6

chi-square test

Answer 6

a statistical test used to determine the probability of obtaining observed proportions by chance, under a specific hypothesis

Question 7

null hypothesis

Answer 7

a hypothesis that proposes no difference between two or more data sets

Question 8

recombination

Answer 8

the process that generates a haploid product of meiosis whose genotypes is different from either of the two haploid genotypes that constituted the meiotic diploid

Question 9

recombinant gamete

Answer 9

any gamete with a genotype that differs from the genotypes of the two haploid parents that fused to form the diploid meiocyte

Question 10

parental gamete

Answer 10

any gamete with a genotype identical to one of the haploid parents that fused to form the diploid meiocyte

Question 11

maternal inheritance

Answer 11

a type of uniparental inheritance in which all the progeny have the genotype and phenotype of the parent acting as the female

Question 12

p > 0.05 means

Answer 12

fail to reject null hypothesis
- deviance due to random chance

Question 13

p < 0.05 means

Answer 13

reject null hypothesis
- deviance is due to something other than random chance
