A postulate is just more or less an assumption of a fact or truth. I think Mendel was able to postulate concerning the behavior of unit factors during gamete formation because he studied this area well and base on his readings he was able to imagine what might be happening during this time.
Answer:
The correct answer would be an option B.
Asexual reproduction is a reproduction in which offspring are produced from a single parent.
It does not involve fusion of gametes and crossing over due to which the offspring contain identical genome as that of parents.
This reduces the genetic diversity in a population due to which all the organisms of a population are at equal risk of extinction under unfavorable conditions such as high temperature, antibiotics, change in pH of surrounding medium et cetera.
Thus, the disadvantage of asexual reproduction is the lack of genetic diversity due to which a single antibiotic is able to kill millions of genetically identical bacteria.
Explanation:
For transverse waves, the waves move in perpendicular direction to the source of vibration. For longitudinal waves, the waves move in parallel direction to the source of vibration . They are similar in the sense that energy is transferred in the form of waves.
Spawn is the eggs and sperm released or deposited into water byaquatic animals. As a verb, to spawn refers to the process of releasing the eggs and sperm, and the act of both sexes is called spawning. Most aquatic animals, except for aquatic mammals and reptiles<span>, reproduce through the process of spawning.
</span><span>There are many variations in the way spawning occurs, depending on sexual differences in anatomy, how the sexes relate to each other, where and how the spawn is released and whether or how the spawn is subsequently guarded.
