Two autosomal genes, J and K, are 60 map units apart. You perform the following testcross: J K / j k x j k / j k. At what freque
Dmitry [639]

Answer:

  • J K / j k = 20%
  • j k / j k = 20%
  • J k / j k = 30%
  • j K / j k = 30%                

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%

Describe the control group for an experiment that examines the effect of fire intensity on the biodiversity of tree communities.
Vladimir79 [104]

Answer:

explanation below

Explanation:

The control group would be the biodiversity of the trees without the fire

The control group in the experiment would center on the biodiversity of the trees without the fire. Ideally, both the control group and the experimental groups are usually identical in every way except that the experimental group would receive the treatment that is believed to have an effect on the biodiversity of trees.

Sexual reproduction begins with sperm and egg cells, which are produced through a process called meiosis. ... In sexual reproduction, a haploid sperm from the male parent fertilizes the haploid egg from the female parent to produce what is called a diploid zygote. Zygote is the technical term for a fertilized egg.
