How to find if two genes are linked or not We can see if two genes are linked, and how tightly, by using data from genetic crosses to calculate the recombination frequency. By finding recombination frequencies for many gene pairs, we can make linkage maps that show the order and relative distances of the genes on the chromosome.

A team of researchers has identified genetic variants that determine the shape of teeth, including a gene inherited from Neanderthals. Read more on this study here: https://lnkd.in/gtnwcVYK

What is a codon? Explanation. What is a codon in simple terms? A codon is a trinucleotide sequence of DNA or RNA that corresponds to a specific amino acid. The genetic code describes the relationship between the sequence of DNA bases (A, C, G, and T) in a gene and the corresponding protein sequence that it encodes. The cell reads the sequence of the gene in groups of three bases. Youtube video: https://lnkd.in/dqFbuCan #nikolaysgeneticslessons

Gene linkage Genetic linkage describes the way in which two genes that are located close to each other on a chromosome are often inherited together. ... In fact, the closer two genes are to one another on Youtube video: https://lnkd.in/dyedvpD4 \#nikolays_genetics_lessons

What are Additive genetic effects? Additive genetic effects occur when two or more genes source a single contribution to the final phenotype, or when alleles of a single gene (in heterozygotes) combine so that their combined effects equal the sum of their individual effects. Non-additive genetic effects involve dominance (of alleles at a single locus) or epistasis (of alleles at different loci). Youtube video: https://lnkd.in/drKhVpic #nikolaysgeneticslessons

3/6 Here, we have identified a new mechanism that explains virulence heterogeneity, not by gene content but by the differential regulation of core virulence genes, driven by differential stress response.

An updated Human Gene Connectome (HGC) based on STRING v12.0 is now available: https://lnkd.in/eYJHksys Providing a biological distance metric between any two human genes, enabling effective prioritization of candidate genes based on known genes.

How to find how many genes control the additive trait Polygenic Traits are Additive. Most traits are polygenic, meaning more than one gene contributes to their phenotypes. In this case, an individual inherits multiple copies of each allele, rather than inheriting one copy of each allele, from each parent. So, when a trait is polygenic, the alleles are additive.
