Cystic fibrosis and other autosomal recessive diseases are not commonly put forward as strong evidential support for the theory of evolution, but being recessive, there is little negative selection pressure to remove the implicated mutations from the gene pool. Another factor to consider is that there are some indications of heterozygous advantage in the form of resistance to cholera, typhoid, diarrhea, and tuberculosis.

How does observed evolutionary change support the scientific theory of evolution?
The theory predicts that evolution will happen and in certain ways. The observed evolution makes this prediction correct. It also defines evolution as happening, and as such is perfect evidence in support of it.
How does genetic variation support Natural Selection?
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
What evidence did Stephen Jay Gould use to support his theory?
The discontinuities in the fossil record that seemed to show that some species or taxons were in a state of non-evolution and then seemed to go through a burst of rapid evolutionary change. This is really only seen in the fossil record and does not have a lot of support in disciplines such as molecular genetic, which genetic divergence back through time in today's genomes.
How Does Homologous Structures Disapprove Evolution?
They don't, Homologous structures, such as the bones in your forearms and the bones in your cat's and dog's forelegs are that similar because you and your pets are mammals and closely related on the evolutionary tree. Before modern genetic showed this to be convincing the study of morphology was showing us pretty much the same thing; homologous structures support evolution.
How does Josiah Strong show that he supports the theory of evolution?
There is strong support for the theory of evolution due to fossils that have been found by archeologists. The fossil records show evidence of evolution over billions of years.
How is DNA utilized as evidence to support the theory of evolution?
DNA is used as evidence to support the theory of evolution by comparing the genetic similarities and differences between different species. By analyzing the DNA sequences of organisms, scientists can trace evolutionary relationships and determine how species have evolved over time. This genetic evidence provides strong support for the idea that all living things are related and have evolved from a common ancestor.
Does genetics support evolution?
Genetics is the study of genes, heredity and variation of living organisms in biology. Molecular genetics supports evolution as its processes work in combination with the environment and experiences of an organism to influence their development and behavior.
What are the four pieces of evidence that support the theory of evolution?
The four pieces of evidence that support the theory of evolution are the fossil record showing transitional forms, homologous structures in different species indicating a common ancestor, genetic similarities between different species, and observable examples of natural selection in action.
Why are most genetic disorders considered lifelong diseases?
Most genetic disorders are considered lifelong diseases because they result from mutations in genes that can affect development and function throughout a person's life. These genetic changes are typically present from birth and cannot be removed or cured, leading to ongoing health issues that may require management and treatment. While some symptoms can be alleviated or managed, the underlying genetic cause often persists, necessitating lifelong care and support.
What are two types of evidence that suggest the evolution has occurred?
Fossil evidence, such as transitional forms showing intermediate characteristics between species, and genetic evidence, like similarities in DNA sequences among related species, both support the occurrence of evolution.
What would be the best way to predict the probability of a baby having Christic fibrosis?
The best way to predict the probability of a baby having cystic fibrosis (CF) is through genetic testing of the parents, specifically looking for mutations in the CFTR gene. If both parents are carriers of the CF gene mutation, there is a 25% chance with each pregnancy that their child will inherit cystic fibrosis. Additionally, prenatal testing methods like chorionic villus sampling (CVS) or amniocentesis can be used to test the fetus directly for CF. Genetic counseling can also provide valuable information and support for prospective parents.
What evidence is there that evolution has occurred?
Evidence for evolution includes fossil records showing transitional forms between species, genetic similarities between different species, and observations of natural selection leading to changes in populations over time. Additionally, comparative anatomy and embryology provide further support for the theory of evolution.
Who provides information to individuals and families on inherited diseases or conditions?
Genetic counselors are trained professionals who provide information to individuals and families about inherited diseases or conditions. They help assess the risk of genetic disorders, explain testing options and results, and offer support and guidance on managing genetic conditions. Genetic counselors work closely with healthcare providers to help individuals make informed decisions about their genetic health.
What are the types of evidence for evolution?
Evolution is the change in allele frequency over time in a population of organisms. This is an observed and observable fact.The molecular, genetic and fossil record all bear out evolutionary change and support one another by being cross correlated. Go here.talkorigins.org
Do Americans support eating disorders?
No, not at all.
What is the idea that evolution is mathematically impossible?
The idea that evolution is mathematically impossible is a misconception. Evolution is a well-supported scientific theory that explains the diversity of life on Earth through gradual changes in populations over generations via mechanisms like natural selection and genetic drift. Mathematical models and evidence from various scientific fields support the concept of evolution.
Is evolutionary true?
Yes, the theory of evolution is widely accepted as a scientific fact. It explains the diversity of living organisms on Earth through the process of natural selection, genetic variation, and adaptation over time. Multiple lines of evidence from various scientific fields support the theory of evolution.
