Answer:
probability of the child having attached earlobes since it is recessive i.e (yy)
=1/4
=0.25 × 100%
=25%
Explanation:
If two heterozygous individuals have a child
i.e let the heterozygous individuals be = Xy
if both traits crosses together; their F₁ offspring will be; (XX, Xy, Xy, yy)
Xy × Xy
X y
X XX Xy
y Xy yy
probability of the child having attached earlobes since it is recessive i.e (yy)
=1/4
=0.25 × 100%
=25%
There are so many examples for that in different areas, like TPBi experiment carried out in our lab recently.Here's one link: http://www.alfa-chemistry.com/tpbi-cas-192198-85-9-item-282866.htm
Answer:
This is unethical.
Explanation:
Every creature contributes one way or the other to the existence of ecosystem,and the stabity of the biodervasity. The whale is one of the major componets of the aquatic biodiversity .Therefore continous killing whch may lead to extinction would distablized rthe bioderstiy and leads to the loss of ecosystem.
Besides,if whales goes into exticntion this would affet the future generations to learn from their existence?Therefore for preservation for future generations,they must be protected for extictinon.
The advent of biotechnology,has shown the genetic products of human and animals could be used to produce genetically modifjed product for humanity Thus if whale goes into exticntion this may not be possible.
<span>The answer to this question would be: tissues; decrease
Oxygen is delivered to the tissue by the heart. It will be unloaded in the tissue, causing the oxygen level in the blood to be decreased. After that, the blood also picks up the carbon dioxide so its level will be increased.
In lungs, the carbon dioxide will be unloaded and oxygen will be loaded back into the blood.</span>
