Answer:
Explanation:
To calculate the recombination frequency, we have to know that 1% of recombinations = 1 map unit = 1cm. And that the maximum recombination frequency is always 50%. 
The map unit is the distance between the pair of genes for which every 100 meiotic products, one of them results in a recombinant one. 
So, en the exposed example:
- J and K are autosomal genes
- J and K are separated by 60 M.U.
- 60 M.U. means that there is 60% of recombination.
Cross)             J K / j k                    x                  j k / j k
Gametes) JK  Parental                                     jk, jk, jk, jk
                  jk   Parental                                   
                 Jk   Recombinant                           
                  jK   Recombinant
One map unit equals 1% of recombination frequency. This means that every 100 meiotic products, one of them is a recombinant one. 
1 M.U. -------------- 1% recombination
60 M.U. ------------ 60% recombination
                               30% Jk  +  30% jK
100 M.U. - 60 M.U. = 40 M.U.
40M.U.--------------40 % Parental (Not recombinant)
                             20% JK   +   20% jk
Punnet Square)           JK       jk      Jk      jK
                           jk     JK/jk   jk/jk   Jk/jk   jK/jk
J K / j k = 20%
 j k / j k = 20%
J k / j k = 30%
 j K / j k = 30%

Answer:
as the question does not contains image i have  already mentioned the link to image in ask for detail section therefore i will answer according to that image.
the answer is "B"
Explanation:
Because before crossing over but after duplication both chromosomes will have same alleles as GgDd therefore according to the image the answer will be option "B". as this option showed duplicated chromosomes.

Answer:
This is a wrong decision.
Explanation:
This decision is not right because by removing wetland means removal of habitat of millions of organisms living in that wetland. The advantages of wetland is more than golf course. Golf course is only used for sport purpose but wetland has a number of purposes i. e. it provides protection against floods which occurs due to climate change, absorb pollutants and enhances water quality.
