Suggest the specific term for the following :(a) Both male and female reproductive organs present in same organism.(b) Y- linked gene(c) Unfertilised egg develops into haploid male bee.

Answer: (a) Hermaphrodite (bisexual) (b) Holandric gene (c) Parthenogenesis (arrhenotoky / haplodiploidy).

• (a) Hermaphrodite / bisexual organism: an organism having both testes and ovaries, e.g. earthworm, tapeworm. (In plants such a condition is called monoecious or bisexual.)
• (b) Holandric gene: a gene present only on the non-homologous part of the Y chromosome; it is passed directly from father to son only, e.g. the gene for hypertrichosis (hairy pinna).
• (c) Parthenogenesis: development of an unfertilised egg into a new individual. In honey bees the unfertilised haploid eggs develop into males (drones) by parthenogenesis (arrhenotoky), while fertilised diploid eggs form females; this is the haplodiploid mechanism of sex determination.
