Vedclass · Answer

(A) The process of fertilisation involves several key biological events:$(1)$ Fertilisation marks the final step of oogenesis,as the secondary oocyte completes its second meiotic division only upon the entry of a sperm.$(2)$ The entry of the sperm induces the completion of the second meiotic division,resulting in the formation of a haploid ovum and a second polar body.$(4)$ Fertilisation prevents the degeneration of the corpus luteum,which continues to secrete progesterone to maintain the endometrium for pregnancy.$(5)$ The fusion of the male and female gametes results in the formation of a diploid zygote.Statement $(3)$ is incorrect because the corpus luteum does not degenerate upon fertilisation; it persists to support the pregnancy.Therefore,the correct statements are $(1)$,$(2)$,$(4)$,and $(5)$.
