Answer:

Malthus.

Explanation:

<em>Malthus formulated what is today known as the Malthusian catastrophe during which he explained that limited resources put a check on the population of humans. He further explained that limited resources will provoke competition.</em>

<em>Darwin later adopted the idea of competition to develop the theory of survival of the fittest, also known as natural selection.</em>

Answer:

a. Ed/eD

b. RF=0.12

Explanation:

The alleles for genes D/d and E/e are:

  • D_: only on neck spikes
  • dd: along back spikes
  • E_: long spikes
  • ee: short spikes

After testcrossing a double heterozygote (DdEe x ddee) there are 4 types of offspring, two of them much more abundant than the other two. The homozygous recessive parent can only produce <em>ed</em> gametes, so the phenotypes of the offspring depend on the gametes that the double heterozygous parent produced.

The offspring was:

  • Ed/ed 79
  • ed/ed 12
  • ED/ed 10
  • eD/ed 76

Total: 177

a) This result suggests that the genes are linked. Since recombination is a rare event, the most abundant phenotypes always come from the parental gametes, and the least abundant come from the recombinant gametes.

<u>Therefore, the genotype of the doube heterozygote parent was </u><u><em>Ed/eD</em></u><u>.</u>

b) Recombination frequency (RF) = Recombinants / Total

  RF = (12+10)/177

  <u>RF = 0.12</u>
