Dogs for trait mapping activity
... We are a group of scientists trying to find the gene responsible for an orange spot in dogs. Dogs are diploid just like humans, which means that they have two copies (alleles) of each gene. For this exercise, the dominant allele is indicated by “A” and the recessive allele is indicated by “a”. Prete ...

Genome evolution
Genome evolution is the process by which a genome changes in structure (sequence) or size over time. The study of genome evolution involves multiple fields such as structural analysis of the genome, the study of genomic parasites, gene and ancient genome duplications, polyploidy, and comparative genomics. Genome evolution is a constantly changing and evolving field due to the steadily growing number of sequenced genomes, both prokaryotic and eukaryotic, available to the scientific community and the public at large.
