Question at position 17 When a sperm nucleus fuses to oocyte nucleus creating a zygote, this is called amphimixis.TrueFalse

Question

BlackTom AI · Accepted Answer

This item tests terminology in fertilization biology. 
Option 1: True. The fusion of a haploid sperm nucleus with a haploid oocyte nucleus to form a diploid zygote is the classical definition of amphimixis. The term reflects the mixing of parental genetic material at the moment of fertilization. 
Option 2: False. If you consider amphimixis to mean something other than the direct nuclear fusion event, you might be thinking of fertilization in a broader sense or misapplying the term. However, in standard biology usage, amphimixis specifically denotes nuclear fusion of sperm and oocyte to create the zygote, so labeling it as False would be incorrect. 
Additional nuance: Some discussions distinguish amphimixis from monospermy or polyspermy or from fertilization processes that involve only membrane fusion without immediate nuclear fusion, but the canonical definition centers on the fusion of the two haploid nuclei to form the zygote nucleus. Therefore, the statement aligns with the established concept of amphimixis, while any alternative interpretation would rely on a nonstandard or broadened definition.
