Mendelian principle of segregation
|
for any particular trait, the pair of alleles of each parent separate and only one allele passes from each parent on to an offspring. Which allele in a parent's pair of alleles is inherited is a matter of chance
|
|
Mendelian principle of independent assortment
|
different pairs of alleles are passed to offspring independently of each other. The result is that new combinations of genes present in neither parent are possible.
|
|
Probability (p)
|
ratio of selected outcomes to the total number of outcomes
|
|
Risk
|
probability that something will happen. genetics refers to the probability of a specific genotype or phenotype
|
|
recurrence risk
|
probability that something will happen again. genetics means probability that a geno or pheno that already exists in the family will show back up in a particular family member
|
|
multiplication rule of probability ('and')
|
the probability that two or more independent events will occur is the product of their independent probabilities
|
|
addition rule of probability ('or')
|
the probability that two or more mutually exclusive events will occur is the sum of the probabilities of each event occuring separately
|
|
binomial expansion
|
p - prob of an event
q - prob of other event (1-p) n - # of trials asked to find frequencies of combinations of p & q in n trials. so (p+q)^n. so what's the pattern as this expands? |
|
binomial expansion formula
|
m - total # of times 'p' occurs
(n!/[m!{n-m}!])*(p^m)*q^(n-m) |
