Chromosome 3 spans about 198 million base pairs (the building blocks of DNA) and represents approximately 6.5 percent of the total DNA in cells. In sexually reproducing organisms, the number of chromosomes in the body (somatic) cells typically is diploid (2n; a pair of each chromosome), twice the haploid (1n) number found in the sex cells, or gametes.

your red blood cells carry oxygen around your body using a protein called haemoglobin. Notably, eight genes with expression across multiple tissues were completely absent or represented by pseudogenes in CanFam3.1 but were now available for interrogation (PSMA4, CDHR5, SCT, PAOX, UTF1, EFNA2, GPX4 and SLC25A22).

To resolve transcript complexity and account for the CanFam3.1 gap closures in GSD_1.0, we generated more than 70M nanopore and PacBio full-length cDNA reads from 40 tissues (including 15 brain regions; Supplementary Table2), and combined this with 24 billion public RNA-seq paired reads (Supplementary Data1).
Genetics is an area with exponential growth in recent years, and much of this is due to recent technological advances that have allowed for the entire genome of many species, including dogs, to be deciphered.

This can be fairly straightforward when studying genes that control appearance, however, it is much more difficult when studying dog disease or behavior (Spady et al. Nowacka-Woszuk, J. et al. It may be that the effect in this region is subtle, and so not detectable with qPCR; however, CYP1A2 is an inducible gene and so the true outcome may only be observed after a drug challenge45.
