Answer:
four phenotypes appear in the ratio 9:3:3:1
Explanation:
<em>For a dihybrid cross in which the two genes concerned obey simple dominant/recessive law and are independently assorting, </em><em>four phenotypes are produced in the ratio 9:3:3:1. </em>
The dominant gene takes up the largest ratio (9/16) while the recessive gene takes up the smallest (1/16). Any deviation from 9:3:3:1 and the number of phenotypes produced from a dihybrid cross is an indication that the genes involved do not obey Mendelian laws.
Explanation:
They differ when they have the same chemical composition but the way in which they are arranged or put together is different.
Circulatory system and nucleus
Answer:
True
Explanation:
Transgenic animals are lines of animals produced by inserting copies of a specific gene or genes into a fertilized egg or early embryo.
I would think that the answer would be C! Good Luck, tell me if it's correct please! :D
