Answer:
3. CABD
Explanation:
The gene mapping refers to providing position to the genes on the chromosomes. The first gene map was constructed by the Alfred Sturtevant on the basis of recombinant produces or recombination frequency which was calculated.
The gene mapping refers to providing position to the genes on the chromosomes.
In the given question to construct gene map:
1. Look for the highest recombination frequency that is 50% between the C and D.
2. Now look for second-highest value and place the gene accordingly.
3.Similarly, place the genes in the decreasing order of recombination frequency and this will result that the sequence of the genes is- CABD.
Thus, Option-3 is correct.
Answer:
a) Both DdPp
b) Yes 3.8%
c) In plant A, the dominant allele D and P are coupled (DP, dp), In plant B they are in repulsion (Dp, dP).
I believe the awnser is B
It was an asteroid that came to earth two billions years ago and scientists says that there might be another one coming.so we might live in space for a couple of months or years. so that why the dinosaur die.
