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:
True
Explanation:
Organic catalyst that increase the rate of biochemical reactions in the cells of living organism s are called enzymes.The are proteins with active sites which are specific to a particular substrate, for enzyme-substrate complex and later enzyme product complex to formed.
They act by lowering the activation energy in the organic chemical reaction therefore increase the rate at which chemical reactions progress.
Hence when the reactions are too slow,activation energy are high,because enzymes are not available to catalyze the reaction fixing the active sites with the the substrates.
