If two outcomes are mutually exclusive, the probability that either will occur is their ______. This is known as the ______________ rule.
|
sum
Addition rule. Example: the probability that we will roll either a 3 or a 4 is 1/6+1/6 = 1/3 |
|
|
If two outcomes are independent, the probability that both will occur is their _________. This is known as the ______________ rule.
|
product
Multiplication rule. Example: the probability that we will roll two sixes on a pair of dice (at once) is 1/6x1/6 = 1/36. |

|
_____________ crosses are when two traits or characteristics are observed or tested at once.
|
dihybrid
|
|
|
A heterozygous tall, green pea plant can create __________ unique gametes.
|
four
|
|
|
If both traits follow simple dominance, than the F2 from a dihybrid cross of two pure breeding parents will show this phenotypic ratio ...
|
9 : 3 : 3 :1
If parents AABB x aabb, then F2 will be: 9 A_B_: 3 A_bb: 3 aaB_: 1 aabb |

|
The chromosome theory of inheritance is
|
a unifying theory stating that inheritance patterns may be generally explained by assuming that genes are located in specific sites on chromosomes.
|
|
|
Complete linkage is
|
the state in which two loci are so close together that alleles of these loci are virtually never separated by crossing over.
|
|
|
The exchange of chromosome parts between homologues by breakage and reunion of DNA during prophase I of meiosis is known as
|
crossing over
|
|
|
The masking of the phenotypic effect of alleles at one gene by alleles of another gene is known as
|
epistasis
