Masteriza [31]

Complete question:

A geneticist is studying two genes. each gene can be either dominant or recessive. a sample of 100 individuals is categorized as follows.

                                         <u>gene 2 </u>

                            <u> dominant</u>     <u>recessive</u>

<u> gene 1 </u>

<u>dominant</u>                    56                24

<u>recessive</u>                   14                  6

(a) what is the probability that a random sampled individual, gene 1 is dominant

(b) what is the probability that a random sampled individual, gene 2 is dominant

(c) given that gene 1 is dominant, what is the probability that gene 2 is dominant

Answer:

(a) what is the probability that a randomly sampled individual, gene 1 is dominant ---> 80%

(b) what is the probability that a randomly sampled individual, gene 2 is dominant ----> 70%

(c) given that gene 1 is dominant, what is the probability that gene 2 is dominant ----> 70%

Explanation:

Due to technical problems, you will find the complete question, the answer, and the explanation in the attached files.

If you are interested in the evolutionary relationship of animals that have four limbs, which of the following would be the outg
trapecia [35]

Answer:

  • First outgroup → Ray-Finned Fishes
  • Second outgroup → Sharks

Explanation:

The outgroup is the most distant taxonomic group that shares no traits or characters with the lineages of interest, which compose the ingroup. You can compare the outgroup with the ingroup to determine the evolutive relationship and which characters are primitive or derived.    

Even though the outgroup shares a common ancestor with the ingroup, this is placed far away in evolution, making the outgroup to be the taxonomic group less related to the other lineages. The lineages in the ingroup share another common ancestor that is more recent in history.

To select the outgroup, you need to focus on what you are interested in. There might be several outgroups, but you should choose the one that is more related or closer to the ingroups. This selection is important because you need to make comparisons to understand the evolution of specific traits.  

In the exposed example, we need to focus on animals that have four limbs. Then, we might assume that the ingroup is composed of Amphibians Crocodiles Dinosaurs. Sharks and Ray-Finned Fish do not have four limbs, so they might be considered outgroups.

From these two outgroups, sharks have a cartilaginous skeleton, while Ray-Finned Fishes have a bony skeleton. This fact makes ray-finned fishes more related to the ingroup than the sharks. So,

  • First outgroup → Ray-Finned Fishes
  • Second outgroup → Sharks

astra-53 [7]
The answer is A.

Prokaryotic organisms are simpler than eukaryotic organisms are are single-celled. They do not contain the genetic information to form complex, specialized structures as eukaryotes do, so they cannot form multi-cellular bodies. The remaining options apply to both prokaryotes and eukaryotes.
