Inbreeding by Chromosome BETA We analyzed the areas of inbreeding across your dog's genome. Below is a graphical representation of your dog's inbreeding, displayed chromosome by chromosome. Any inbred areas appear in blue, while outbred areas appear in yellow. 7 10 13 16 19 22 25 28 31 34 37 STR TRACKS: Show Hide 2 5 8 11 14 17 20 23 26 29 32 35 38 3 6 9 12 15 18 21 24 27 30 33 36
Genetic Variation
Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.
Quantitative Genetics
Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.
The figures below depict shared chromosomal regions between 2 full-sibling humans (Figure A) and inbreeding localized to chromosomal regions in a dog (Figure B). Despite these figures being described differently for humans and canines, they are based on the same genetic principle. Identify this principle and describe how this principle is used/reflected in the two figures.
