MONOHYBRID CROSS
The inheritance of flower color in the dog flower (Snapdragon or Antirrhinum sp.) can be understood by crossbreeding between true-breeding red-flowered (RR) and true-breeding white-flowered plants (rr). When they were crossed, F₁ (Rr) was pink. When F₁ was self-pollinated, the F₂ results were Red, Pink and White. Here the genotype ratios were exactly as expected, but the phenotype ratios have been changed. What happened was that R was not completely dominant over r and this made it possible to distinguish Rr as pink from RR (Red) and rr (White).
What will be the genotypic ratio in F₂ generation when F₁ (Rr) was self-pollinated?

The resistance of the platinum wire of a platinum resistance thermometer at the ice point is 10 \(\Omega\) and at steam point is 10.46 \(\Omega\). When the thermometer is inserted in a hot bath, the resistance of the platinum wire is 11.6 \(\Omega\). Calculate the temperature of the bath.
