AG 3301 - Genetics Pop Gen Practice problems Answer the following questions. Be sure to show your work for full credit! 1. At the C locus in horses, chestnuts (sorrels) are CC, palominos are Coc, and cremellos are cca. In a herd of 10 horses, 3 are chestnut, 6 are palominos and 1 is cremello. What are the gene and genotypic frequencies at the C locus in this herd? CCP = 3/10= .3 Cc H=6/162.6 =1r CL R = 1/10 = ol & 10

Answer 1
