Select all statements that are true. 1) By selecting the genetic information that is passed on to future generations, genetic engineering is similar to natural selection. 2) Unlike natural selection, genetic engineering selects the organisms most beneficial to the environment. 3) By selecting the genetic information that is passed on to future generations, genetic engineering can happen at a different rate than natural selection. 4) Like natural selection, genetic engineering may be used on all organisms, including humans. 5) The effects of genetic engineering apply only to the organism selected, but natural selection affects the entire population.

In a population of guinea pigs, short hair is dominant to long hair. If 25 percent of a breeder’s guinea pigs has long hair, what is the frequency of the recessive allele (q)?5 percent
15 percent
25 percent
50 percent

Answers

If 25 percent of a breeder’s guinea pigs has long hair, the frequency of the recessive allele (q) is 50%. Let A be dominant allele and a be recessive allele. The frequencies are as following: p - the frequency of dominant allele, q - the frequency of recessive allele, p^2 - the frequency of genotype AA (short hair), 2pq - the frequency of genotype Aa (short hair), and q^2 - the frequency of genotype aa (long hair). So, we know that q^2 = 25% = 0.25. We need to find q. q = √q^2 = √0.25 = 0.50 = 50%.

Answers

When part of the catch is discarded and not used is called a "bycatch". This occurs when other, usually smaller fish, get caught by accident by fishermen hoping to catch other kinds of fish.

Over years of selective breeding, French bulldogs have developed extremely short snouts and flat faces. These traits, although attractive to the dog owners, can make it difficult for the dogs to breathe.Which of the following processes led to the presence of these traits?(Choice A)
A
Artificial selection

(Choice B)
B
Natural selection

(Choice C)
C
Environmental selection

(Choice D)
D
Sexual selection

Answers

Choice A, artificial selection, led to the presence of these traits in French bulldogs.

What is Artificial selection?

Artificial selection, also known as selective breeding, is the process of breeding organisms with desirable traits in order to produce offspring with those traits. In the case of French bulldogs, humans selectively bred dogs with shorter snouts and flatter faces in order to create a breed that was aesthetically pleasing. However, these traits also led to health problems such as difficulty breathing.

Natural selection, on the other hand, is the process by which organisms with advantageous traits are more likely to survive and reproduce, leading to the evolution of those traits in a population.

Environmental selection refers to the process by which the environment favors certain traits over others. Sexual selection is a type of natural selection that occurs when individuals with certain traits are more likely to attract mates and reproduce.

In the case of French bulldogs, these traits were not naturally selected for based on survival advantages, nor were they the result of environmental or sexual selection. Rather, they were artificially selected for by humans, leading to unintended consequences for the dogs' health.

Explanation:

Which prevents the Lac genes in the DNA of E. coli from being expressed most of the time

Answers

The Lac repressor prevents the Lac genes in the DNA of E.coli from being expressed most of the time. The Lac repressor is actually a kind of DNA binding protein. It is a fact that in case there is an absence of lactose, the Lac repressor binds to the proteins. I hope that this answer comes to your help.

Answer:

The correct answer would be lac repressor.

Lac repressor refers to the DNA binding protein which inhibits or prevents the expression of genes in the DNA of Lac Operon.

The lac repressor protein is expressed by the Lac regulatory region.

It binds to the operator region of the operon and prevents the binding of RNA polymerase.
