A. True
"Charles Darwin is known as the father of evolution, but in fact Alfred Wallace, another British naturalist, was a co-discoverer of the theory- though Darwin got the most credit"
The answer is b the protists
Answer:
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Mutations can occur during DNA replication if errors are made and not corrected in time.

Answer:
You can use any of these questions, or all of them! I hope this will be helpful.
1.) How did scientists find out that llamas could be helpful?
2.) What will be done to the llama to find a cure, will the animal be hurt in any way?
3.) How long would it take until the cure could actually take action in the body?
4.) Could this be potentially harmful to be injected/ingested?
5.) What is the estimated time that it will take for this cure to become?
Answer:
bright blue trait = recessive
yellow trait = dominant
Explanation:
let the letter B represent the gene for skin colour.
This means that the dominant gene is 'B' while the recessive gene is 'b'
A dominant gene is one that is exhibited phenotypically in the presence of both gene variants (heter0zygous state - Bb) while a recessive gene is only expressed phenotypically when it is in a h0m0zygous state (bb)
In order to find out the genotype of the parents, let us consider each cross one after the other.
1. A bright blue female and a bright blue male produce all blue progeny.
2. A yellow female and a yellow male produce a mix of both bright blue and yellow progeny
From statement 2, it can be deduced that the trait for yellow colour is dominant because a cross of the parents exhibiting this trait produces bright blue offsprings too, meaning that the genetic composition of the parents contains the gene that codes for yellow colour. Since these parents show a yellow colour in a heterozygous state, then the trait for yellow colour is dominant.
Therefore, the genotypes of the parents in each case include:
1. A bright blue female and a bright blue male produce all blue progeny. (bb × bb)
2. A yellow female and a yellow male produce a mix of both bright blue and yellow progeny (Bb × Bb)
