Answer:
The correct answer is option B) "Species trees should be constructed using multiple loci (both nuclear and mtDNA)".
Explanation:
Gene genealogy is defined as the inference of relationships between individuals by using DNA testing in combination with the analysis of traditional genealogical and historical records. Gene genealogies could not be established using an unique genetic loci, since not always the same loci vary among individuals. Therefore, species trees should be constructed using multiple loci (both nuclear and mtDNA), to avoid erroneous inferences obtained by analyzing loci that do not vary among individuals.
A chromosome deletion occurs when a chromosomal fragment is lost. Thus the chromosome is missing some genes. One example of this in humans is know as cry of the cat. It occurs from a deletion on a chromosome number 5. A child that is born has a mental disability a small head with unusual facial features and cries like the sound of a distressed cat. The children rarely live into adulthood.

Answer:
The independent variable is the amount of glucose being supplied and the dependent variable is the amount of alcohol being produced.
An independent variable can be described as the variable which is being changes in a scientific experiment so that its effects can be studies.
The dependent variable can be described as the variable which is under study and which gets affected by the changes in the independent variable.
The control that can be designed for this experiment can be another experiment in which the amount of glucose is kept constant in each of the yeasts.

Explanation:
Each eukaryotic chromosome usually has repeated telomere sequences ranging from 2 to as many as 2000.
There is normally just one specialized DNA sequence called the centromere per eukaryotic chromosomal DNA molecule.
The origin of replication is the site where DNA duplication starts in S phase.
The centromere attaches the chromosome to the mitotic spindle via the kinetochore structure.
Teleomere contains repeateted sequences at the ends of the chromosomes.
