Answer: option D - Four abnormal gametes
Explanation:
Nondisjunction occurs in the Anaphase phase of Meiosis I. It happens that at least ONE pair of homologous chromosomes FAIL to separate, resulting in two daughter cells having an EXTRA copy of one chromosome (e.g XXY) and two cells that are missing that chromosome (e.g XO).
Thus, Nondisjunction results in Four (4) abnormal gametes
The given question is incomplete as it does not have the options which are:
A. commensalism
B. mutualism
C. parasitism
D. predator-prey
Answer:
B. mutualism
Explanation:
The species in the ecosystem interact with each other in many ways and one such type of interaction in which both the species are equally benefitted is known as the mutualism.
When one species provides benefit to second species whereas the second species provides benefit to the first species in a way that the evolution has transformed the relationship into an inseparable or highly dependent relationship.
In the given question, the shrimp provide a safe habitat to the goby fish whereas goby fish protect the shrimps from the predators. Since both the species are benefitting each other therefore the species form a symbiotic relationship.
Thus, Option-B is the correct answer.
It's D the only choice close to the hypothesis
