(c) In thelytoky, the diploid egg parthenogenetically develops into males 

(d) In arrhenotoky, the male develops from unfertilised egg and the female from fertilised egg

Answer 1

Correct option: (d) In arrhenotoky, the male develops from unfertilised egg and the female from fertilised egg

Arrhenotoky and thelytoky are forms of natural parthenogenesis. In Arrhenotoky, as in honeybee, the male develops from unfertilised egg and the female from fertilised egg. In thelytoky, the diploid unfertilised egg parthenogenetically develops into female.
