Question

One of these statements about apomixis is incorrect
A. Formation of seeds without fertilization
B. Meiotic division and fertilization of gametes take place to form a zygote
C. Seeds are genetically similar
D. None of these

Answer 1

Hint:
Before we proceed with the problem, it is important to know about apomixis.
Apomixis, according to Hans Wrinkles, is the process of switching from sexual to asexual reproduction without fertilization. In apomixis, sexual reproduction is not present. Apomixis is very important because it helps to produce healthy offspring, allows the desirable plant traits to be preserved, and allows for the creation of hybrid plants by crossing the two.

Complete step by step answer:
Apomixis, which occurs in flowering plants, is the asexual production of a seed from the maternal tissues of the ovule without undergoing the meiosis and fertilization processes that lead to the development of an embryo.
The process of an ovule's diploid cell going directly through mitosis without first going through meiosis to form an embryo sac is referred to as "apomixis." Plants created by apomictic embryos have the same genetic makeup as their parents, making them genetic clones.
There is no meiotic division and gamete fertilization to produce a zygote in this instance, though. The entire process is stopped, and apomixis is used to produce seeds. It comes in two varieties: Sporophytic - From the diploid sporophyte, apomixis develops in this kind.

Option ‘B’ is correct

Note:
Due to the mother cell's diploid nature, a diploid embryo is created. Therefore, "Without fertilization, a diploid embryo forms" is the appropriate response. In higher plants, it can be visible. It maintains plant genetic diversity. This procedure allows for the permanent maintenance of heterosis in agricultural plants. Without meiosis and gametogenesis, asexual reproduction occurs.
