You repeated the same question twice but the answer is hypothesis.
The answer is purple and smooth.
It is known that the in dihybrid cross (a cross between two
different traits), the phenotypic ratio between the offspring of two heterozygous parents in the F2
generation is 9:3:3:1.
<span>purple and smooth = 75 (</span><span>≈ 9 </span><span>· 8)</span>
<span>white and smooth = 28 (</span><span>≈ 3 </span><span>· 8)</span>
<span>purple and wrinkled = 24 (= 3 </span><span>· 8)</span>
<span>white and wrinkled = 8 (= 1 </span><span>· 8)</span>
<span>
</span>
So, the ratio between the offspring is close to 9:3:3:1 in F2 generation.
This means, that the only heterozygotes are present in the F1 generation, and they must be purple and smooth.

Explanation:
Transitional fossils help scientists bridge gaps in the tree of life, resulting in a picture of gradual evolution over millions of years.
Answer:
Brain is the main coordination center of the body and regulates the proper functioning of the body. Brain is divided into three parts- forebrain, midbrain and hindbrain.
Cerebrum: Crerebrum is the largest part of brain and controls the language, communication ability, and the process of learning and memory of an organism.
Hypothalamus: Hypothalamus is located at the base of a brain. Hypothalamus releases various hormones, regulates the body temperature and manages the sexual behavior of an organism.
Thalamus: Thalamus is located above the brain stem and relay the neurons into the cerebral cortex. Thalamus regulates alertness, wakefulness and sleep of an organism.
