In tomatoes, red fruit is dominant to yellow fruit and hairy stems are dominant to hairless (smooth) stems. The two genes controlling these traits are inherited in normal Mendelian fashion and are not linked.
a) Produce a suitable key for this information in terms of the individual alleles of the genes given.
b) What are the possible genotypes of plants showing the following forms:
i) Red fruit and smooth stems
ii) Yellow fruit and hairy stems
iii) Red fruit and hairy stems
c) On crossing a plant with red fruit and hairy stem, with one that was yellow fruit and hairy stem, the following progeny were obtained:
30 red, hairy / 11 red, smooth / 29 yellow, hairy / 9 yellow, smooth
Give a reasoned explanation along with the use of full genetic diagrams to proof your answer, to explain these results in terms of the simultaneous transmission of characteristics.
Do you think that Fischer-type Carbene complexes are more stable than schrook type?Why?
In a different species of plant, bell shaped flower is dominant to tube shaped flower and the gene controlling this trait is inherited in normal Mendelian fashion. Flower colour can be either red, white, or in combination pink. The two genes are not linked.
Give a reasoned explanation along with the use of full genetic diagrams to proof your answer, to explain in terms of the simultaneous transmission of characteristics, the possible outcomes of crossing a heterozygous bell flowered plant with pink flowers, and a tube flowered plant with white flowers. You should also clearly identify the phenotypic combinations that are not possible from this cross.

Hi, please help me with this question, especially with parts 1 and 2.
Describe the process of catalytic reforming in the petroleum refining industry
your answer must also include:
1) A balanced chemical equation, physical states included, and reaction conditions stated.
