Always start with the genotypic ratios, because they'll be the same. Since hidden variation is popping out, you can assume that both of the parents are heterozygous. The problems you get will be the F2 ratio of the cross between two homozygous individuals.
1:2:1 is the genotypic ratio for one locus. AA:Aa:aa.
1:2:1 is the phenotypic ratio for incomplete dominance. Incomplete dominance means that the heterozygote expresses differently from either homozygote.
3:1 is the phenotypic ratio for complete dominance.
2:1 is the phenotypic ratio for lethal recessive.

<span>The characteristic of a chronic illness is that it leaves a patient with a permanent disability which can be physical or mental. This disability affects the day-to-day life activities of the patient, preventing the patient from performing activities of daily life. The patient may need family support for performing daily activities. In an acute illness, the patient returns to a fully functional life after treatment; in chronic illness the patient may not be able to resume a normal life. The treatment is more effective in acute illness; patients with chronic illnesses are less likely to respond to treatments in later stages.</span>
