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%
Tying the legs and wings of poultry against the body to make a compact unit for cooking is called trussing.
The purpose of this is even cooking an a more attractive appearance.
When injected, benzedrine, dexedrine, and methamphetamine increase the release of serotonin, norepinephrine, and dopamine in the brain. Benzedrine, dexedrine, and methamphetamine are examples of amphetamines. They are stimulants, which speed up the messages travelling between the brain and the body. They may be used to treat attention deficit hyperactivity disorder.
Answer:
There is no short answer.
Explanation:
The chlorophyll is the pigment that gives the plants' leaves their green colors and it is also responsible for the photosynthesis process which takes place in the mitochondria. In the fall as the leaves change color, the amount of chlorophyll decreases and this impacts the mitochondria as it also decreases the amount of work the mitochondria does.
I hope this answer helps.
