18. Coat color in shorthorn cattle is determined by incomplete dominance. Individuals homozygous for the red allele (CRC) have red fur, individuals homozygous for the white allele (CWCW) have white fur, and heterozygous individuals (CCW) are roan (brown and white). A second gene in these cattle determines if they will have horns. The horned allele (H) is dominant to hornless (h). Predict the genotypic and phenotypic ratios of the offspring if a heterozygous horned-roan bullis crossed with a hornless -...

6. In tigers, a dominant allele (W) is responsible for the expression of the normal orange pigment. Individuals that inherit twe recessive alleles (w) lack the normal orange pigment in their fur, appearing white with black stripes. A pair of normally colored parewis produces a cub that is white with black stripes and scab that is orange with black stripes. What are the possible genotypes of the cube? b. What are the possible genotypes of the parents? 6. Explain your...
