Answer 1,2,3,4:
As both are heterozygous therefore Male genotype will be (BbEe) and the genotype of female will be (BbEe). While both will have the phenotype black.
Parent Genotype
Male X Female
BbEe X BbEe
 Possible gametes from Parents
Male X Female
BbEe X BbEe
(BE) (Be) (bE) (be) X (BE) (Be) (bE) (be)
...
F1  generation will have following genetypic ratio
Black Labrador = 9  = B_E_
Brown Labrador = 3  = bbE_ 
Yellow Labrador = 3  = B_ee
Yellow Labrador = 1  = bbee
Furthermore, the phenotypic ration will be
Black Labrador = 9
Brown Labrador = 3
Yellow Labrador = 4
 
        
             
        
        
        
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.
