Discover more types of non-Mendelian inheritance such as incomplete dominance and codominance with the Amoeba Sisters! This video uses vocabulary that was previously defined in the Amoeba Sisters Monohybrid Crosses video.

List of single gene traits in humans

Human example of incomplete dominance; myostatin-related hypertrophy.  Results in an overgrowth of muscle tissue.

3 minute video Each father and mother pass down traits to their children, who inherit combinations of their dominant or recessive alleles. But how do we know so much about genetics today? Hortensia Jiménez Díaz explains how studying pea plants revealed why you may have blue eyes.

While the loss of these animals is concerning for species conservation, now researchers at the University of Florida have shown that overhunting can have widespread effects on the forest itself. Overhunting leads to the extinction of a dominant tree species, Miliusa horsfieldii, or the Miliusa beech, with likely cascading effects on other forest biota.

Even if you look like your mother, an innovative study suggests that not only humans but, in fact, all mammals are genetically more like Dad. We inherit equal amounts of genetic material from each parent, yet that coming from our father's side is more likely to take action, according to the study that was published in the journal Nature Genetics.

Jackson would eventually be diagnosed with the rare genetic eye disease Autosomal Dominant Neovascular Inflammatory Vitreoretinopathy (ADNIV), which eventually causes blindness in those who carry the gene.

ach of the four hallmarks of autosomal dominant inheritance are fulfilled. Each affected individual has an affected parent; there is no skipping of generations. Males and females are equally likely to be affected. About 1/2 of the offspring of an affected individual are affected (the recurrence risk is 1/2). Normal siblings (II-3) of affected individuals have all normal offspring.

This PowerPoint-driven, flipped case study begins with a short video about a woman suffering from cystic fibrosis (CF) in the 1970s, a friend of the lead author's, whom she met in college and who died in her twenties. Hooked by this personal story, students then delve into the genetics and biology of cystic fibrosis as they learn about the difference between dominant and recessive genes, make Punnett squares that depict various types of inheritance, distinguish between probability and actual numbers, differentiate types of mutations, and learn about the opportunistic infections that CF patients often succumb to.  Students conclude the case by watching two additional videos on chest compression machines and the contemporary life expectancy of patients with CF.  In addition to the scientific content presented in the case, it is hoped that students will empathize with, and be motivated by, the young people presented in the videos as they struggle with a very real, incurable disease deeply rooted in genetics.

There are few areas of science more fiercely contested than the issue of what makes us who we are. Are we products of our environments or the embodiment of our genes? Is nature the governing force behind our behaviour or is it nurture? While almost everyone agrees that it's a mixture of both, there has been no end of disagreement about which is the dominant influence.

Managing manure to reduce emissions can be economically viable for larger enterprises or cooperative facilities that use the captured methane to generate heat and electricity. For small operators, the offset value alone is unlikely to warrant the large capital cost of infrastructure. This activity contributes to carbon farming. Agriculture is responsible for 14% of Australia's greenhouse gas emissions and is the dominant source of methane and nitrous oxide, accounting for 56% and 73%, respectively, of Australia's emissions.
