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.
Answer: There will be no effect on the protein produced
Explanation:
According to the genetic code, the triplet codon GAG code for the amino acid, glutamate, while GAC code for aspartate.
Since GAG and GAC code for amino acids with similar properties (aspartate and glutamate are both acidic amino acids due to the extra carboxyl group present in their side chain), the change in nucleotide is still similar to the original, so will result in a different amino acid sequence, but will not alter the function of the protein at all. Thus, this kind of mutation is called silent mutation.
Answer:
Tree frogs use plants as protection. Golden jackals, once they have been expelled from a pack, will trail a tiger to feed on the remains of its kills. Goby fish live on other sea animals, changing color to blend in with the host, thus gaining protection from predators.
Explanation:
Well, flowers give insects like bees and butterflies nectar. That's their food. In return, the insects spread the flower's pollen so that other plants like its type can be fertilized.
This is mutualism - a symbiotic relationship were two organisms benefit.
