Answer:
Hutton and Lyell
Explanation:
James Hutton and Charles Lyell were geologists who believed the history of the Earth to be vast and directionless. James Hutton formed the theory of Uniformitarianism which was spread by Charles Lyell. According to this theory, Hutton and Lyell described that there are some forces present on the Earth which are involved in creating the vast history of the earth. They argued that Earth was far older than what other people believed and certain geological processes over a period of time shaped it.

Answer:
9/32 Pink, Tall and Normal individuals Rr Tt Nn
Explanation:
<u>Available data:</u>
- Red color RR
- Pink color Rr
- White color rr
- Normal NN and Nn
- Symmetrical nn
- Tall TT and Tt
- Dwarf tt
1st Cross:
Parental) rr TT NN x RR tt nn
F1) 100% RrTtNn
2nd Cross:
Parental) Rr Tt Nn x Rr Tt Nn
Knowing that these three genes assort independently, then we can infer that the F2 will have the next phenotypic proportions for each gene:
RR= 1/4 Red
Rr= 2/4 Pink
rr=1/4 White
TT + Tt= 3/4 Tall
tt=1/4 Dwarf
NN + Nn = 3/4 Normal
nn=1/4 Symmetrical
- The proportion of the F2 plants that will resemble Rr Tt Nn (Pink, tall, Normal) in Phenotype
Rr= 2/4 pink
TT + Tt= 3/4 Tall
NN + Nn = 3/4 Normal
2/4 x 3/4 x 3/4 = 18/64= 9/32
