Punnett squares use the  ____________  ofgametes to determine the genotypes and phenotypes of all possibleoffspring.

Two laws of probability apply to genetics. The product rulestates that the chance of two eventsoccurring  ____________  is equal to themultiplied probabilities of each of those two eventsoccurring  ____________ .

The sum ruleadds  ____________  probabilities to determinethe  ____________  probability for anevent.

When events are described with the word \"and\",the  ____________  rule is used. Eventsdescribed using the word \"or\" often usethe  ____________  rule.

The results of one-trait and two-trait crosses, depending uponthe  ____________  of the gametes, have certaincharacteristic ratios that describe the genotypes and phenotypes ofthe offspring.

The sum rule is used to determine this value when the results ofeach  ____________  are added.

Skin color and height are examples of polygenic traits that arecontrolled by  ____________  sets ofalleles.

Polygenic traits are graphically represented asa  ____________ curve.

In polygenicinheritance,  ____________  alleles all codefor product and have a  ____________  effect onphenotype.

The effects are additive and result ina  ____________  of phenotypes.
