lozanna [386]

Answer:

a) Genotypes & Phenotypes in F1 generation

TtRr, Tough and Red seeds

b) Tender pods

Genotypes - ttRR (1), ttRr(2), ttrr (1)

Proportion will be 3/16

c) Red seeds

Genotypes - TTRR, TTRr (2), TtRR (2), TtRr (4)

Proportion will be 9/16

d) Tender pods & red seeds

Proportion will be 3/16

Explanation:

Tough pods (T) are dominant to tender pods (t)

Red seeds (R) are dominant to (r) green seeds

True breeding species

a) Tough pods and red seeds - TTRR

b) Tender pods and green seeds - ttrr

F1 generation -

TTRR * ttrr

TtRr

All the offspring will have TtRr genotype. The Phenotype of all offspring will be tough and red seeds.

F2 generations -

Self crossing the F1 generation species, we get -

TtRr * TtRr

Gametes - TR, Tr, tR , tr

TR Tr tR tr

asambeis [7]

Answer:

We fear flying in a plane, nuclear power plants or being struck by lightning more because our risk perception isn't rational. We assess risks using a mixture of cognitive skills (weighing the evidence, using reasoning and logic to reach conclusions) and emotional appraisals. In this case, we believe that overheating or lack of exercise is something we can control. We believe we can feel the process taking place and we can react in time. We fear all the situations that we cannot control.
