You have been given three plants: Two have solid black flowers, and one has grey flowers. You cross each black-flowered plant to

the grey plant with the following results:
Parents: black #1 X grey F1: 87 solid black, 83 spotted black
Parents: black #2 X grey F1: all black
To try and make sense of these results, you intercross the solid black-flowered F1 plants from cross #2 with the following results in the F2:
132 black
35 spotted black
11 grey
What are the genotypes of the parents, F1 and F2 generations?

In labrador retrievers, a common breed of dog, black coat is dominant to chocolate, normal vision is dominant to progressive ret
marshall27 [118]
The data given regarding the alleles are as follows
black(B)-dominant , chocolate(b) - recessive
normal vision - dominant, progressive retinal atrophy - recessive 
normal hip joint - dominant, hip dysplasia - recessive 

lets first consider one trait 
parents are heterozygous 
when crossed            Bb         x          Bb
offspring               BB      Bb     Bb     bb
                             --------black-----  chocolate
the probability of dogs being black - 3/4
                           dogs being chocolate - 1/4
likewise for the other two traits 
probability of normal vision - 3/4 and retinal atrophy - 1/4
probability of normal hip joint - 3/4 and hip dysplasia - 1/4

we have to calculate the probability of 1st pup being born is
chocolate - 1/4 
normal vision - 3/4
normal hip - 3/4
since all these traits should be acquired the probability of having the above three traits is calculated by getting the product of individual probabilities 
therefore answer is 1/4 x 3/4 x 3/4
  probability              = 9/64

Why is glycolysis thought to be one of the earliest of all biochemical processes that evolved?
Fed [463]
<span>Scientist believe that glycolysis is one of the very first biochemical processes that evolved due to some hard evidence. First, all living organisms perform glycolysis. The genes used in the process of glycolytic enzymes are always conserved at a high rate. Glycolysis has been found to predate atmospheric oxygen and photosynthesis due to the fact that it happens in anaerobic conditions. Finally, it also has been found to happen in cytosol which means it would have begun occurring prior to eukaryotes.</span>
