NEET 2010 Biology question

Apomictic embryos in citrus arise from :

(1)Maternal sporophytic tissue in ovuleCorrect
(2)Antipodal cells
(3)Diploid egg
(4)Synergids

Answer: (1)

Solution

Apomixis is the production of seeds without fertilisation. In citrus (and mango) many embryos develop from diploid cells of the nucellus (and integuments), which are maternal sporophytic tissue surrounding the embryo sac.
