There would be less genetic variation in humans
Uuu codes for the amino acid phenylalanine in humans and bacteria Theis is due to which property of the Genetic code?

Which would most likely decrease the genetic variation in the human population?
If the human population was reduced to a very small number of interbreeding individual then this small population, denied outbreeding, would have very little genetic variation. Humans, who went through a bottleneck event about 70,000 years ago, are considered a " small " species because they have little genetic variation in comparison to many other species. Google cheetah to see how this concept works.
Why might it be difficult to perform genetic analysis in humans?
It takes many generations for humans to mature, grow, and die making them not the ideal subject for genetic analysis because there lifetimes are so long.
What would be would be the least satisfactory organism for genetic research?
humans
What are the two main of genetic variation?
The two main sources of genetic variation are mutations, which are changes in the DNA sequence, and recombination, which occurs during meiosis when genetic material is exchanged between homologous chromosomes. These processes contribute to genetic diversity within populations.
Why do humans have homologous structured?
For genetic variation to take place
Why do some huskies have blue eyes?
The same reason some humans do. Genetic variation
What would be the result if crossing over didnt happen during meiosisin humans?
There would be less genetic variation in humans
What would happen if crossing over didn't happen during meiosis in humans?
There would be less genetic variation in humans
Do humans have more or less genetic variation than most species?
Humans have lower genetic variation compared to other species due to the bottleneck effect experienced in human evolution. This is because human populations are relatively small and have undergone significant reductions in genetic diversity.
What factors contributes to genetic variation between humans?
the genes that code for RNA and proteins...............
What conclusion would be MOST appropriate about the genetic variation between humans and the three apes as illustrated by the phylogenetic tree?
The phylogenetic tree suggests that while humans share a significant amount of genetic variation with the three apes—chimpanzees, gorillas, and orangutans—humans are distinct from them, indicating a common ancestry. The closer the branches of these species are to one another, the more recent their common ancestor, which highlights that humans and chimpanzees share the most genetic similarity. Overall, this illustrates the evolutionary relationships and the extent of genetic divergence among these species.
How can genetic variation help human and life?
Genetic variation is crucial for the survival and adaptability of species, including humans, as it provides a diverse pool of traits that can enhance resilience to environmental changes, diseases, and other challenges. It facilitates evolution by enabling populations to adapt over generations, leading to improved survival rates. Additionally, in humans, genetic diversity plays a key role in health and disease susceptibility, influencing responses to treatments and the effectiveness of medications. Ultimately, genetic variation is essential for the dynamic and changing needs of life on Earth.
How do humans use variation for your benefit?
Humans harness variation through selective breeding in agriculture and animal husbandry, allowing for the development of crops and livestock with desirable traits, such as increased yield or disease resistance. Additionally, genetic variation in populations contributes to adaptability and resilience against environmental changes, benefiting ecosystems and human survival. In medicine, understanding genetic variation enables personalized treatments and the development of targeted therapies. Overall, variation enhances innovation and problem-solving across various fields.
Why do humans not have the same genetic information as someone else?
Humans do not have the same genetic information as someone else because each individual inherits a unique combination of genes from their parents. This genetic variation results from the random assortment of genes during sexual reproduction and can lead to differences in traits, characteristics, and susceptibility to diseases among individuals.
Which would likely decrease the genetic variation in the human population?
If the human population was reduced to a very small number of interbreeding individual then this small population, denied outbreeding, would have very little genetic variation. Humans, who went through a bottleneck event about 70,000 years ago, are considered a " small " species because they have little genetic variation in comparison to many other species.
