I think the answer is B, that most amino acids are encoded by more than one codon.
The BRCA 1 and BRCA 2 genes are two genes that are sought in the genetic study of an individual in order to seek a predisposition to breast cancer (in women and also in men).
The genes of Tay-sachs, are researched in order to diagnose or eliminate Tay-sachs disease.
The first difference lies in the goal of the research: for the BRCA (screening) genes, a predisposition is sought and for the Tay-sachs genes, it is sought to confirm the disease.
The second lies in the technique used:
The first step in the study of these genes is to isolate and replicate them. The best technique for this is the PCR (polymerase chain reaction). By using primers we can amplify the gene we want. So the primers used in BRCA and Tay-Sachs research are necessarily different.
Answer:
50%
Explanation:
(TT) Is fully tall. (TS) Is medium. So it can be assumed that (SS) is short. When forming a cross, you cross TT and TS to generate a phenotypic ratio of 1x1 or a genotypic ratio of 1 TT, 1 TS. Making it exactly split in half in 50/100.
Hope this helps!
Answer:
The offspring will also be white and homozygous.
Explanation:
If the two cats are white and homozygous where the gene B is for black color and dominant, gene b is for white color and recessive. In this case the genotypes of the two cats are going to be "bb" which can only lead to the same genotypes and phenotypes in their offspring. They will also be white and homozygous.
I hope this answer helps.
