Answer:
Thorough observation and understanding of dominance types
Explanation:
It is very simple to distinguish between traits following complete dominance or incomplete dominance
There can be three cases of dominance
a) Complete dominance - where characteristics of one allele are expressed over and above the characteristics of the other allele
b) Incomplete dominance - Here both the traits are dominant but a blending of the two traits occur for example red and white flower producing pink flower
c) Co-dominance - Here both the traits are dominant but no blending occurs between the two traits occur for example red and white flower producing flower with red and white bands
Based on the above definitions , pattern of complete dominance is followed or not in case of snapdragon can be depicted.
In the coding region, natural selection tends to eliminate all of the mutations because of the high importance these regions have. The coding region contains genes that synthesize proteins and the changes in the DNA sequence can have devastating effects on the cell. Therefore, there are very few differences in the sequences of coding regions that can help us trace the lineage.
On the other hand, in the non-coding regions, the mutations often accumulate because they have little effect on the cell and the adaptive value of the organism. This enables us to trace up the lineage by comparing the sequences and seeing the differences in the sequences.
Answer:
(b) - A mnemonic device
Explanation:
A mnemonic device -
It is a technique used by a person to improve or faster the process of a learning .
This can be done by using some codes or tricks to make the concept or words easy and interesting , and can be easy learned .
hence ,
in the question , Luke used the mnemonic to learn the four bases of DNA quickly and efficiently .
