<span>Notice a couple of things
different between (A) and (B). It was NOT the first time a biologist
proposed that species changed through time (so it's not B). But it
finally *solidified* that idea by giving "change through time"
(evolution) a MECHANISM. It gave a plausible explanation for WHY
species change over time, in a testable way that made sense and had
evidence to support it.
So it finally dismissed the idea that species are constant.
It also emphasized that the simple presence of *variation* within a population was a key reason for evolution.
While we're at it ... (C) is wrong because it's not *individuals* that
acclimate (adapt) to their environment, but the population (the species)
as a whole.
And (D) is wrong because it had nothing to do with economics or the monarchy.</span>

Answer:
All eight phenotypes are possible but parental phenotypes will be more in number
Explanation:
In the cross MmDdPp X mmddpp eight types of offspring are possible because MmDdPp will produce eight types of gametes. These offspring are:
- MDP/mdp
- Mdp/mdp
- mDp/mdp
- mdP/mdp
- MDp/mdp
- mDP/mdp
- MdP/mdp
- mdp/mdd
In absence of linkage, the genes would have assorted independently producing all the eight types of offspring in equal number. Hence the phenotype ratio would be 1:1:1:1:1:1:1:1.
If the genes are linked they will show the tendency to get inherited together and crossing over will not take place up to the expected degree. Hence fewer recombinants will be produced and more parental type offspring will be produced.
