While genes have potential to modify behavior, behavior can also modify genes. How do genes impact this process? How do genes determine the traits of an organism? How does the Chromosomal Theory of Inheritance helped to advance our understanding of genetics?
How Do Recessive Traits Occur? When an individual has two recessive alleles, the phenotype is the recessive trait. For example, let's suppose that there are two versions of a gene, or alleles, that determine whether or not a person can roll their tongue. One allele, the dominant one, is...
Understanding how genes affect traits is an important part of scientific literacy in the twenty-first century. However, studies have shown the challenges of teaching and learning these multilevel mechanisms. Research in science education has mapped some of the reasons for students' difficulties and ...
Do we have the evidence necessary to start screening potential husbands for specific combinations of genes that seem harmful to marriage? I would not recommend doing so for a few reasons. Foremost is that genes can influence a broad range of characteristics, which may be detrimental to a marriag...
How do fish fins come into being and how do fins evolve into terrestrial tetrapod limbs? To answer this scientific question is substantially to understand how the genes that determine these traits are subject to natural and sexual selection, and how they thereby involve the innovation mechanics and...
How do you find the frequency of a recessive allele? How could you determine the distance between two genes using experimental mating? How many autosomal genes are there? How do you graph to represent the distribution of traits? (inheritance) How does independent assortment of chromosomes increas...
Even though these beloved traits have a basis in genetics, that doesn't mean they're set in stone. After all, one trait may require collaboration of multiple genes. According to cognitive psychologist Scott Barry Kaufman, a hereditary advantage for a trait that might lead us to great things ...
By locking together traits that work well together, supergenes provide striking evolutionary advantages. But they can also be costly because they make it nearly impossible to purge bad mutations
How are autosomal traits, including recessive, genetic? How are alleles and traits related? How can genetic disorders be autosomal dominant and autosomal recessive? Does X-DNA affect autosomal inheritance? What do genes determine? What is Mendelian genetics?
