In mangoes wide leaf and narrow leaf are alternative characters and wide (W) is dominant to narrow (w). Red stem and green stem are another pair of characters with red (R) dominant to green (r) . A true breeding wide, green mango plant was crossed with a true-breeding narrow, red plant and the F1 plants were interbred. 337 F2 plants were produced with the following phenotypes; 202 wide, red; 69 wide, green; 15 narrow, green; 51 narrow, red. What probability is associated with the Chi Sq value you obtain?

When many families were tested for their ability to taste the chemical PTC, the parental pairs were grouped into three types and the progeny totaled. The results were as follows Parents # of Families Tasters Nontasters Taster x taster 425 929 130 Taster x nontaster 289 483 278 Nontaster x nontaster 86 5 218 Assuming that PTC tasting is dominant (P) and nontaster is recessive (p), how can the progeny ratios in each of the three types of matings be accounted for?
