Answer: Natural selection.

Explanation:

The concept of natural selection was given by Charles Darwin.
According to this concept, in a given environment the organisms that possess better adaptations have higher chances of survival and, leave behind a greater number of progenies.
When malaria outbreak occurs, the allele frequencies change and only the organisms that possess the alleles which help them to survive this outbreak due to resistance against malarial infection will be selected by nature and hence, this is an example of natural selection.

A wild-type tomato plant (Plant 1) is homozygous dominant for three traits: solid leaves (MM), normal height (DD), and smooth sk

Brut [27]

Answer: In this type of cross between MmDdPp and mmddpp, the phenotypic ratios in the eight possible phenotypes are as follow; a. solid, normal, smooth = 1:8

b. solid, normal, peach = 1:8

c. solid, dwarf, smooth = 1:8

d. solid, dwarf, peach = 1:8

e. mottled, normal, smooth = 1:8

f. mottled, normal, peach = 1:8

g. mottled, dwarf, smooth = 1:8

h. mottled, dwarf, peach = 1:8

Explanation: The number of gametes that can be formed from a particular genotype is given as 2^n where n is the number of heterozygous loci. In the genotype MmDdPp, n = 3. Therefore, 8 gametes can be formed.

In genotype mmddpp, n = 0. Therefore, only one type of gamete can be formed.

Crossing the two genotype (MmDdPp and mmddpp) as shown in the attached image, 8 possible offsprings can be achieved. Phenotypes of these offspring had been stated earlier. The phenotypic frequency of each of these offspring is one out of eight (⅛).
