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.
They are caused because b. the land heats and cools more quickly than the water.
<span>The correct answer would be C. The adrenal glands, which are also known as suprarenal glands, are glands that belong to the endocrine system. Adrenal gland produces the steroids aldosterone and cortisol and various hormones including adrenaline which help in the response of an individual to stress. They are found above the kidneys. Each of the gland has an inner medulla and an outer cortex which produces steroid hormones. The adrenal cortex has three zones which are zona glomerulosa, the zona fasciculata and the zona reticularis.</span>
Answer:
a video that shows penguin species that have different mating dances
Explanation:
The question is incomplete as it does not have the options which are:
- a video that shows a large river that has penguin populations on both sides
- a video that shows penguin species that have different mating dances
- a video that shows a penguin that is laying eggs
- a video that shows penguins in a tidal pool and an open ocean
Answer:
a video that shows penguin species that have different mating dances
<em><u>The reproductive isolation is the factor which allows the species to evolve and form a new species, therefore, this factor is used to describe a species.</u></em>
<em><u /></em>
<em><u>The reproductive isolation refers to a mechanism in which the species are isolated to not interbreed with the individual of other species. The reproductive isolation could be due to behavioural, psychological, physical or genetic differences. evolved as an adaptation.</u></em>
<em><u /></em>
<em><u>In the given cases, the penguin species which shows different mating dances is considered to be reproductively isolated as the different dance rituals evolved as behaviour to prevent them from mating.</u></em>
<em><u /></em>
<em><u>Thus, the selected option is correct.</u></em>
