Such an important topic. We regularly share news about new diagnostic approaches and progress with novel therapies but access and cost are a significant issue with the gulf between the “haves” and “have not” growing. Those working with rare diseases want to help all of those affected but ensuring that no-one is left behind as we move towards targets of improved diagnostics and meaningful treatments is a challenge we all need to consider.

Meet Florida Institute for National Security (FINS) faculty member, Dr. Connie Mulligan, director of the Human Genetics Lab, that explores various topics such as #HumanGenetics & #BioculturalInvestigation. Her research at FINS focuses on topics such as #HumanDisease, #ComplexPhenotypes and #HumanEvolution & measures the effects these topics have on #NatSec. #get2knowfins_uf https://lnkd.in/dqCDfnDH

How to solve Probability Problems in Genetics Genetics is almost unique among the sciences, in that its fundamental laws were stated as probability laws. Thus the probabilities we compute have a reality as long-run frequencies, and are not just subjective. Youtube video: https://lnkd.in/d9MB3wma #nikolaysgeneticslessons

Why extra-genetic inheritance matters in evolution: "During the twentieth century, scholars of evolution focused on the slowly changing aspects of evolutionary adaptation and the most stable components of inheritance—namely, genetic processes. We predict that in the twenty-first century a new consensus will emerge, in which adaptation is understood to involve multiple complementary mechanisms operating on different time scales, supported by diverse forms of inheritance beyond genes, and where faster-acting (that is, extragenetic) processes are recognized to be important components of the adaptive system".

Incomplete dominance and Hardy-Weinberg equilibrium In population genetics, the Hardy_Weinberg principle, also known as the Hardy_Weinberg equilibrium, model, theorem, or law, states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences. Population genetics is intimately bound up with the study of evolution and natural selection, and is often regarded as the theoretical cornerstone of modern Darwinism. This is because natural selection is one of the most important factors that can affect a population's genetic composition. Natural selection occurs when some variants in a population out-reproduce other variants as a result of being better adapted to the environment, or fitter . Presuming the fitness differences are at least partly due to genetic differences, this will cause the population's genetic makeup to be altered over time. By studying formal models of gene frequency change, population geneticists therefore hope to shed light on the evolutionary process, and to permit the consequences of different evolutionary hypotheses to be explored in a quantitatively precise way.

Tongue-rolling: The myth. Some people can roll their tongue into a tube, and some people can't. This is one of the most common traits that biology teachers use to demonstrate basic genetic principles. Alfred Sturtevant (one of the pioneers of Drosophila genetics (https://lnkd.in/g-6Shb_J)) described tongue rolling as a simple two-allele character, with the allele for rolling (usually given the symbol T or R) being dominant over the allele for non-rolling (t or r) (Sturtevant 1940). Many studies have shown that the myth is incorrect, but tongue rollin g remains a popular subject in genetics classes. https://lnkd.in/gwKvQ3T5 Dentaltown Tongue Rolling Isn't Genetic and Practice Makes Perfect. https://lnkd.in/giBHj_5N
