Where do new alleles arise from?

Answers

Answer 1

Answer:

Gene mutations provide new alleles, making these mutations the ultimate source of variation. A gene mutation is an alteration in the DNA nucleotide sequence, producing an alternate sequence, termed an allele. Mutations occur at random, and can be beneficial, neutral, or harmful.

Which approach would be least helpful in determining genetic differences between species?

Answers

Answer:

the least helpful would be a straight up guess, the best way would be to to back in the history of that species and study how they lived and survived and reproduced and all that stuff

Explanation:

Comparing physical characteristics between species is not a reliable method for determining genetic differences because many physical traits are influenced by environmental factors and may not necessarily reflect the underlying genetic differences between species.

What is an example of this ?

For example, two species may have different fur colors or patterns, but this difference may be due to environmental factors such as exposure to different types of light rather than genetic differences.

In contrast, analyzing DNA sequences can provide a more precise and objective way to identify genetic differences between species. By comparing the DNA sequences of different species, scientists can identify variations in genes and regulatory regions that may be responsible for differences in traits or behaviors between species.

This approach can also reveal the evolutionary relationships between species and provide insights into how genetic variation has driven the diversification of life on Earth.

Therefore, Advances in genomic technologies have made it increasingly feasible to sequence and compare the genomes of diverse species. Comparative genomics has already revealed many insights into the genetic basis of traits such as human disease susceptibility, adaptation to environmental challenges, and the evolution of complex traits such as intelligence and social behavior.

The breaking down of starch into its component sugars would be an example of
A. Catabolism
B. Cell Division
C. Protein Synthesis

Answers

Answer:

A. Catabolism

Explanation:

Catabolism is the process by which complex molecules are broken down into simpler molecules, like starch to component sugars or proteins to amino acids. Cell division is the process by which a parent cell will divide into two or more daughter cells, like mitosis or meiosis. Protein synthesis is the process by which proteins are made, this is through transcription and translation.

A letter about the evidence of evolution

Answers

Answer:

I am writing this in response to a letter regarding evolution. Evolution is increasingly solid, not shaky. Darwin’s “theory” or explanation was a way of understanding what he had discovered (which did not include genes, chromosomes, DNA or nucleotide bases). Our explanations now include genetics and the commonality of mutation.  

Proofs are solid, not in question by serious scientists. Direct observation is one, which we see in the fact that this year’s flu evolved a little too far from last year’s, so flu shots are less effective this year than we would like them to be.  

Fossils tell the story well: whales with legs, dinosaurs with feathers and Tiktaalik. The latter was found in the Canadian north and is part fish, part amphibian, before there were ever any amphibians. Imperfection is a good proof: think of your useless appendix, the very bad design of your ankles, knees, and back (talk to a chiropractor about that).  You have big toes because they used to be useful thumbs for your grasping feet.

Many other animals and even plants similarly have flaws that show their evolutionary past. Two large human chromosomes reflect the coming together of two chimpanzee chromosomes each.
