Question

Allogamy is very useful because it results in :
A. Formation of male – offsprings
B. Weaker progeny
C. Superior progeny
D. Formation of seeds

Answer 1

Allogamy by and large alludes to the fertilization of an ovum of a creature with the spermatozoa of another, for the most part of similar species. Autogamy, conversely, is self-fertilization, for example, fertilization happening on a blossom when the ovum is treated with its own dust (as in self-fertilization). Allogamy is favorable over autogamy.

Step by step answer: Allogamy is additionally called cross-fertilization. On account of allogamy, the dust from a bloom falls on the blossom of an alternate plant. This makes the hereditary recombinations happen. This is beyond the realm of imagination in some other kind of fertilization. In this way, it creates the predominant offspring. For example, strawberries, grapes, etc. So, option C is correct. Allogamy, the combination of male and female gametes (sex cells) from various people of similar species. It is, therefore, not only to produce male offsprings, i.e., option A is incorrect. The genetic combination is the characteristic feature of allogamy not seen in any other pollination type.
As allogamy is an advanced feature, it does not produce weaker progeny, i.e., option B is incorrect.
Fertilization results in seeds. It is not necessary that all plants possessing allogamy produce seeds. So, option D is incorrect
Hence, option C is correct.

Note: Cross-fertilization must happen in dioecious plants (those having male and female organs on isolated people) and in all creature species wherein there are discrete male and female people. Indeed, even among bisexuals—i.e., those creatures where similar individual produces both sperm and eggs—numerous species have very much evolved components that guarantee cross-fertilization. In addition, a considerable lot of the androgynous species that are equipped for self-fertilization additionally have abilities for cross-fertilization.
