Smooth seed shape is dominant to wrinkled. The F2 generation is as follows: 3/4 smooth: 1/4 wrinkled.  What is the expected F1 genotypic ratio?

At the molecular level, what is the explanation for whythe four-o’clock flowers are pink instead of red?

Tenera is grown for consumption seeds not as a source of oil palm seeds so it is not recommended to plant uncertified fruit/seeds, why? Explain by making crosses starting from parental (Dura and Pisifera) to F2 complete with pictures of the fruit and its gene structure and the cross chessboard.

Green leaves are dominant to red. Long petals are dominant to short. Cross a homozygous green, heterozygous long and a homozygous red, homozygous long. Give phenotypic ratio and show Punnett square.
