Answer:
Yea there is no diagram I can answer it if you edit the question and put a diagram.
Explanation:
Answer:
3:1
Explanation:
Parents : Tt x Tt
↓ ↓
Gametes : T, t T, t
Progeny : TT, Tt, Tt, tt
Phenotype of F1 generation = 3:1
Genotype = 1:2:1
Hence, probability of having tasters and non-taster children is 3:1 .
Answer:
The main challenge is the poor quality of samples.
Explanation:
The decomposed body would be a bad source of genetic material because every cell on that buried body is at high risk of being decomposed, therefore every genetic material on that body would be as well at risk of being preserved. Given this scenario, there is a low chance that a cell could be used as a sample for different analysis. The main purpose to preserve such material is to be able to compare to other relatives of the body and to determine who really is that body.
Student 2 is right.
<h3>Constant variables</h3>
In research investigations, some variables should be kept constant across various experimental groups in order for the outcome of the investigation to be valid.
For example, in order to test how flatworms respond to different environments, one variable that should be kept constant is the flatworms. The flatworms to be used must be of the same species, sex, age, etc.
The investigator can then go ahead to divide the flatworms into two or more groups and then subject them to different environments. Other variables should also be kept constant in order to determine the effects that are only specific to the different environments only.
