<span>In 80% of the cases of offspring with cri-du-chat syndrome, the father's gametes were the source of the deletion of the chromosome as opposed to the mother's egg being the cause. Therefore, cri-du-chat is largely caused by the father's genetics, not the mothers.</span>
A, B and C are the events that will cause an ecological disturbance.
Rationale:
A. Introduction of a new species: When a new specie is introduced, it increases the competition in ecosystem with the native species for food, water, space and shelter. This affects the reproductive success of the native species and thus the dynamics of ecosystem.
B. Climate change: Climate change is different from a simple change of weather. The best example would be of Antarctica where the ice is melting fast due to the global warming. The native species find it harder to adapt to the warm temperatures.
C. Late spring snowstorm: Spring is the season where the plants grow and animals shed their fur. When snowstorms occur in this season they harm these plants and animals that live there.
Answer:
Parent´s chances:
- Mom´s chances of giving their children the big feet allele are 2 out of 2, or 100%
- Mom´s chances of giving their children the small feet allele are 0 out of 2, or 0%
- Dad´s chances of giving their children the big feet allele are 1 out of 2, or 50%.
- Dad´s chances of giving their children the small feet allele are 1 out of 2, or 50%
Offspring chances:
- The offspring have 4 out of 4 or 100% of probability of having big feet. And 0 over 4 or 0% of probabilities of having short feet.
