Answer:

Natural selection

Explanation:

The action of natural selection consists in selecting individuals more adapted to a given ecological condition, eliminating those disadvantaged for that same condition. The most appropriate expression refers to the greater probability of a given individual surviving and leaving descendants in a given environment.

Natural selection acts permanently on all populations. Even in stable and constant environments, natural selection acts in a stabilizing manner, is present, eliminating deviant phenotypes. However, the environment does not represent a constant and stable system, either over time or over space, which determines different interactions between organisms and the environment.

Natural selection is the principle that postulates that hereditary traits that provide a reproductive or survival advantage are more likely than alternative traits to be passed on to subsequent generations and are therefore chosen over time.

After crossing over as shown below what would the sequence of genes be for each of the chromatids
SashulF [63]

The sequence of the genes will be ABCD, abCD and abCd, abcD.

Full question is attatched below.

<h3><u>Explanation:</u></h3>

The genes in the chromosomes are denoted as the sequence of genes present in a single chromatid of a particular chromosome. Thus, the genes here in this question are to be mentioned as ABCD and not as abab.

Crossing over is the process by which the homologous pair of chromosomes do pair up in the Prophase 1 of meiosis 1 division and they exchange a particular part of their DNA with each other. This leads to exchange of genes between the homologous chromosomes, which will form different gametes in near future. This brings about a variation between the offsprings of same individuals.

Here the d gene of the two chromosomes are getting exchanged.

So the chromosomes will become ABCD, abCD and abCd, abcD respectively.

Answer:

<em>The correct option is A) cadmium dosage</em>

Explanation:

In an experiment, an independent variable can be described as a factor which is changed naturally or by us to see its effect on the dependent variable. The dependent variable is the variable which is under study and depends on the independent variable.

In the following experiment, we are checking the effect of different dosages of cadmium on the surviving ability of tadpoles. Hence, cadmium dosage is the independent variable. Tadpole population is the dependent variable.
