Some Special Mechanisms of Reproduction and Incompatibility

Asexual reproduction mode of seed formation is called:

Apomixis is

What is Nucellar embryo?

Parthenogenesis is

I. A single plant can't show both apomixis and polyembryony.

II. Presence of multiple embryos in multiple ovules is called polyembryony.

III. Species of grass family can produce seeds without fertilisation.

Find the correct options with respect to above lines:

Assertion: Apomictics do not show segregation of characters in their progeny and therefore have huge potential in hybrid seed industry.

Reason: Apomictic seeds are produced without fertilization.

The correct option among the following is:

The development of gametophyte from the vegetative part of the sporophyte without the intervention of spores is called:
Or
The formation of gametophyte from the sporophyte (without meiosis) is called:

Statement - '$\mathrm{X}$': Apomixis is seen in a few flowering plants such as some species of Asteraceae and grasses.
Statement - '$\mathrm{Y}$': Apomixis is a form of asexual reproduction that mimics sexual reproduction.

Statement - '$\mathrm{Z}$': In some species of apomictic seeds, the diploid egg cell is formed without reduction division.
Choose the correct option.

Polyembryony is seen in

Apomixis is seen in

Identify the incorrect statement about parthenocarpy.

Non-sexual method of reproduction is:

During fertilisation in plants the male and female gametes unite, triggering the process of cell division followed by seed formation. A gene $\mathrm{BBM}1$, expressed only in the male gamete, is responsible for eliciting rapid cell division. A researcher overexpressed the $\mathrm{BBM}1$ gene in the female gamete that resulted in the multiplication of the female gamete into an embryo and then the seed. The plants obtained from these seeds were genetically identical to the parent. This phenomenon is commonly seen in a few select plants naturally, and is known as

Fruits develop without fertilization are called:

Listed below are different plant reproductive strategies.

I. Parthenocarpy

II. Syngamy

III. Apomixis

IV. Polyembryony

Which of them can give rise to a clonal progeny having the same genotype as that of the mother plant?

Polyembryony is reported in
(i) Citrus
(ii) Mango
(iii) Gossypium
