WebGenetic Stability of Inbred Mice The mutation rate in eucaryotes is generally 109. This means that there are about three point mutations per generation. Nearly all of these will be in non-coding, probably "meaningless" regions of the genome. Any new mutation is heterozygous in one parent. WebWhole-genome sequencing revealed many mutations fitting the recessive inheritance pattern in this region including two deleterious mutations in the TPO gene, chr17:800788G>A (686F>V) and chr17:805276C>T (845T>M). ...
