How can you determine if a bacterium is being killed by an antibiotic or if its growth is simply being inhibited

Biology

Answer:

"You need to take a swab from the zone of inhibition and use it to inoculate a new plate without the antibiotic. If the organism grows then it was simply held in a static state by the antibiotic."

The probability of obtaining a yellow-fruited plant from the cross is ¼ or 25%.

<h3>WHAT IS A HETEROZYGOUS CROSS</h3>

A heterozygous cross is a cross between two individuals that are heterozygous for two genes.

According to this question, white (W) fruit color is dominant over yellow (w). If two white-fruited individuals with genotypes that are unknown are crossed i.e. Ww × Ww.

The offsprings of this cross are as follows:

  • WW
  • Ww
  • Ww
  • ww

Therefore, the probability of obtaining a yellow-fruited plant from the cross is ¼ or 25%.

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%
