Assuming a typical monohybrid cross in which one allele is completely dominant to the other, what phenotypic ratio is expected i
IgorC [24]

Answer:

Assuming the dominant allele is represented as A, and the genotype as AA and the recessive as a, and genotype as aa; then the F1 will produce the offispring. Aa, Aa, Aa,Aa in ratio: 1:1:1:1:1

This shows the dominance of allele A.

However if two of  the F1 generation are crossed then:

The  F2 is AA,Aa,Aa,aa the phenotypic ratio is

                        3   ;     1

W<u>hile the Genotypic ratio is ratio;</u>

<u>   1AA : 2Aa Aa; 1aa(1 ;2;1)</u>

identify an independent variable in the experiment graphed in figure 1. based on the data in figure 1, identify a control that s
choli [55]

Answer:

Explanation:

This question is incomplete because of the absence of the graph. However, the independent variable of an experiment is the variable that is not affected by any other variable during the course of the experiment but is however intentionally or unintentionally predetermined by the researcher conducting the experiment. For example, in an experiment to determine the effect of age on blood pressure; age is the independent variable because the age class/groups of the individuals to be used can be determined by the researcher also the age cannot be affected by the pressure (the age of a person cannot change because of an increase/decrease in blood pressure).

Also, the control of an experiment is the variable/data in which other data in the same experiment are compared to. For example, in an experiment to determine the effect of a substance (such as sepin-1) on the growth of cancer cells (using a culture medium), the control can be the culture medium that was not given any substance or the culture medium that was given a pure substance of no effect like water. This means, in this control culture medium, the cancer cells will continue to grow normally while that growth will be compared with what is seen in the culture medium treated with sepin-1.

What is meant by evolution through natural selection
VikaD [51]
Hello!

Natural selection is the way that animals evolve. 

The theory of natural selection is that the animals that do not have a specific trait to survive in their environment will die. The animals that do have the trait will survive. The animals that survive will then pass the trait down to their offspring, who will also likely survive because they have the trait. This is how species evolve and continue to survive in their environment. 

The species evolve because only the fittest survive (this is known as "survival of the fittest"). The animals that do not have the needed traits will die and they cannot have offspring. 

I hope this helps answer your question! Have a great day!
