Can an unfertilised, apomictic embryo sac give rise to a diploid embryo ? If yes, then how ?
Yes, if megaspore develops into embryo without meiotic division then egg cell is diploid. Diploid egg cell develops into embryo by mitosis.
Note : Apomixis is a type of asexual reproduction, in which seeds are produced without fertilisation.
Which of the following process is helpful in hybrid seed production:
How many sentences are correct?
- To produce seeds without fertilisation is called apomixis
- Occurance of more than one embryo in a seed is referred to as polyembryony
- The pollen grains represent the male gametophytes.
What is Apomixis ? Give its importance.
In agamospermy, the embryo sac is diploid because it is formed without meiosis. Such embryo sac may develop from
Nucellar polyembryony is reported in species of
