Both parents are normal. But, some of the kids have the disease. This indicates that the parents are heterozygous for the disease (let's use Dd). They are phenotypically fine because D is normal. But we know they must both carry the diseased d allele because their kids have the disease.
If you cross Dd x Dd you get DD, Dd, Dd and dd as the possible outcomes. But because each time they have a child they roll the dice as to which of the 4 above happens, they were unlucky as 3 of those times they got dd for their child...so 3 of them have the disease (and are dd). One is phenotypically normal but could still be Dd or DD.

Answer and Explanation:
A maternal impact quality is a quality the incipient organism doesn't express, rather, it is a quality the mother communicates, that by one way or another has an effect on the improvement of the hatchling. Models incorporate qualities that decide extremity of the incipient organism, and qualities that decide the body plan of the developing life, for example, bicoid in Drosophila, which decides head and thorax position.
The bicoid quality figures out which end is the front finish of the fetus. A homozygous transformed bicoid quality outcomes in the absence of foremost fragments, for example, mouth parts, head, and the initial two thoracic portions. It additionally brings about a hatchling creating two back closures (thus the name bicoid).
The phenotype of the hatchlings will be typical, since the mother is ordinary, and it is a maternal impact quality.
The descendants would be transformed as depicted above
Answer: Increase
According to the competitive exclusion principle, when two or more species in an ecosystem are competing for the same resource. The one which has undergone favorable adaptation and more competing will be likely to derive those resource than the one which has not undergone adaptation or less adaptive to the environment and less competing. Squirrels and chipmunks compete for the same food source and this food source became scare one of the two species is likely to disappear according to the competitive exclusion principle because the degree of competition between two species will increase.
