When two aurea coloured snapdragon `F_1` plants are crossed, we will get 1:2 ratio instead of the 1:2:1 raio. Why? Give the inheritance pattern.

When 4 O' clock plant with red flower is crossed with white flower, the F_1 plant produces pink flower. What is this type of inheritance? Explain the inheritance at the molecular level.

A yellow colour flower plant indicated by YY is crossed with white color flower plant denoted by yy. (a) following the Mendelian inheritance pattern , what would be the flower color is first filial generation ? (b) Which Mendelian principle is illustrated in this cross ? (c) Derive the cross and state the phenotypic ratio of yellow flowers to white flowers in F_2 generation ?

When two unrelated individuals or lines are crossed, the performance of F_1 hybird is often superior to both its parents. This phenomenon is called

The masses of two planets are in the ratio 1:2 their radii are in the ratio 1:2. Find the ratio of the acceleration due to gravity on the planets .
