Ssee x sSEe3 Rehpogs are mythical creatures. They are small and not very smart. Rehpogs live on the ground in a flat, warm habitat. Their fur texture and color ranges from thick purple fur to thin pink fur, depending on allele distribution. The dominant fur allele (R) codes for thick purple fur. The recessive allele (r) codes for thin pink fur. REMEMBER: a phenotype (fur color) is the physical expression of a genotype (two- letter code for the alleles present in that individual). Each individual has two alleles for fur color: RR genotype is homozygous dominant - Thick purple fur phenotype Rr genotype is heterozygous = Thick purple fur (because of the presence of one dominant allele) rr genotype is homozygous recessive = Thin pink fur (because of the absence of a dominant allele) e For the purposes of this experiment, Rehpogs mate once per year and produce two offspring each year. Rehpogs are monogamous, faithful and fertile. Part I A small population of genetically diverse Rehpogs (equal numbers…QUESTION 8 In snowpeople, broomstick arms are dominant to twig arms and carrot nose is dominant to button nose.
