Answer:
James Watson and Francis Crick solved the structure of DNA. Rosalind Franklin and Maurice Wilkins, also contributed to this discovery.
Explanation:
<h3><u>Answer;</u></h3>
The law of independent assortment
<h3><u>Explanation;</u></h3>
- The Principle of Independent Assortment illustrates how different genes individually separate from one another when reproductive cells receive.
- Independent assortment of genes and their similar traits was first mentioned by Gregor Mendel in 1865 during his studies of genetics in pea plants.
- When two or more characters are acquired, individual hereditary factors classify independently during gamete production, giving distinct traits an equal opportunity of befalling together.

Answer and Explanation
Mendel selected a group of dwarf plants and sel pollinated them by dusting mature pollen grains onto them. He then collected the resulting seeds and planted them and noticed these seeds germinated and grew into dwarf plants only.
He also selected tall plants and self-pollinated them. the resulting seeds he observed that they grew into a micture of tall and dwarf plants. He took the seeds of tall plants only and repeated the experiments for many generations until he obtained only tall plants.
He then crossed cross-pollinated purebreeds tall garden pea with pure breed variety. He planted the seeds and observed the offsprings were all tall plants. He crossed two of these tall offsprinf from the F1 and planted the resulting seeds. the second filial generation consisted of a mixture of tall and dwarf plants.
He counted these plants and noted that the ratio of tall to dwarf was about 3:1. From this, he postulated that there are now laws governing inheritance.The law of independent assortment and law of segregation.
Flying foxes disperse the Cycad seeds if the seed sometimes get swallowed whole.
Explanation:
- Cycads are gymnosperms they do not have seeds enclosed in fruit. Therefore the bats are not attracted to cycad fruit.
- If the bats were susceptible to neurotoxin then they must not have been the frequent feeders of cycad seeds. Biomagnification of neurotoxin in flying fox is a widely researched topic.
- Beetles do not have an association with these bats thus the bats must not be assisting them as important pollinating agents.
