(2) (taxonomy) Common name for Araschnia levana, a species of butterfly endemic in central and eastern Europe


Supplement

Biological maps are useful tools to determine relative positions of biological elements. Examples of biological maps are those used in genetics and neuroscience. In genetics, a map that shows the arrangement of genes on chromosomes is called genetic map. It also indicates the location of certain genetic markers and their relative position to one another. Another biological map is a brain map wherein brain activities are depicted. The map shows which areas in the brain have relatively higher or lower activities.

Which mountain range was formed first (historically)?

Source 1: http://i.stack.imgur.com/rYNf0.png Source 1 shows a map of a particular area. In this map you will find the mountain ranges 1 and 2, the species P, Q and R. Two possible pedigrees of the ancestral history of the species P, Q and R are ...

Genes in the same linkage group are inherited together?

... away (*allele frequency of gene C is not known)? If it's too far away from each other to come to a valid evolutionary inference, what is a maximum map distance (cM) where you would confidently say the genes are under the same selection? If there is any paper on this topic, please let me know! Thanks

Re: Genes in the same linkage group are inherited together?

The map distance tells you how closely linked the genes are. The shorter the map distance, the higher the probability of co-inheritance and the more tightly linked the genes are ("tightly linked" and "close map ...

Genes in the same linkage group are inherited together?

... you say a gene is in a linkage group, does that mean that most likely all the genes in the linkage group are inherited together regardless of a map distance (centimorgans)? Or is it that genes in the same linkage group are more likely to be inherited together than a gene in linkage group A is ...

Re: Genetics Hard problem!

Based on the information in Experiment II, estimate the minimum genetic map distance between the two genetic loci. (Note: One genetic map unit (m.u.) gives a recombinant frequency (RF) of 1 percent.) I scanned the whole passage in the attachment. Answer is ...
