In one experiment Lederberg used Gal and Gal– strains of E. coli. One half of a plate that contained medium with galactose as th

e only carbon source was inoculated with phages that came from lysed cells of the Gal strain. The other half of the plate was left uninoculated. A Gal- strain was then placed on the entire plate. Numerous colonies appeared on the half of the plate inoculated with the phage, whereas only a few appeared on the half that was not inoculated with phage. Explain what happened using appropriate terminology.

Answer:

This is an example of adaptation due to a progressive mutation

Explanation:

At the beginning, the bacteria can use the galactose as carbon source for it needs, but since this food is getting out in every new generation. The new generations can be adapted to survive with smaller quantities of galactose until there will be one generation that can survive with any galactose source, when this offspring reach the area of the plate without galactose, then it can be grown in ant area.

The information in the table shows the possible genotypes resulting from the mating of two heterozygotes aadd. the allele a code
tensa zangetsu [6.8K]
Admitting that the "a" is a capital A for normal pigmentation and "d" is a capital D for dimpled chin, meaning that these are the dominant traits, the fraction expected to be albino with a non-dimpled chin is of 1/16.
When two heterozygous are crossed and two characteristics are being analysed, the offspring quantity that will possess the two recessive traits can be represented by 1/16. This is easily confirmed when a Punnett square is made. Considering that both parents were heterozygous, on both sides of the crossing in the Punnett square, you would have the following alleles' combination: AD, Ad, aD, and ad. The offspring that would be homozygous recessive (aadd) would correspond to only 1/16.
