Amelogenin (AMEL) is a gene responsible for tooth bud development. It is located on the X-chromosome, thus called AMELX, in mammals. AMEL has been shown to be present in fish, amphibians, and reptiles, though the exact location on the chromosome has not been determined. Amelogenin-like gene (AMELY), an AMEL homolog encoded on the Y-chromosome in some mammals, including sheep, cattle, deer, bears, humans, and some primates, is shorter than the sequence on the X-chromosome. It is unknown whether AMELY is transcriptionally active, but it has been found to be useful for human sexing purposes in forensics, archaeology and prenatal diagnosis, …

Identification Of A Genetic Marker For Litter Size In Sheep, Olivia Price
Undergraduate Honors Capstone Projects
The purpose of this experiment was to determine if the estrogen receptor gene (ESR) could be used as a genetic marker for litter size in sheep. The estrogen receptor gene was chosen because it has been successfully used as a genetic marker for litter size in swine. In this study, DNA dilutions from two experimental flocks, totaling approximately 200 animals, were used. Amplification of exon 1/intron 1 of the ESR gene was performed using PCR. Initial results indicated a polymorphism in the gene when cut with the restriction enzyme Ava ll. It appeared that the gene contained a deletion with …
