In horses, the allele for black coat color (B) is dominant, and the allele for brown coat color (b) is recessive. If a black horse with the genotype Bb is crossed with another black horse with the genotype Bb, what are the possible genotypes and phenotypes of their offspring?
NON-MENDELIAN INHERETANCE
In a species of cows, coat color is determined by two alleles: B (black) and W (white). The alleles exhibit codominance, meaning both alleles are expressed in the heterozygous condition. What will be the coat color of a cow that has the genotype BW?
A population of crabs living on a sandy beach exhibits three colors: dark brown, light brown, and speckled, as shown above. The genotypes for these colors are BB for dark brown, bb for light brown, and Bb for speckled. The speckled color blends in extremely well with the color of the sand on the beach. The pattern appears to provide the speckled crabs with some protection from predatory birds.

In guinea pigs, two traits are being considered: coat color and fur texture. The allele for black coat color (B) is dominant over brown (b), and the allele for short fur (S) is dominant over long fur (s). If two guinea pigs, both heterozygous for both traits (BbSs), are crossed, what are the possible genotypes and phenotypes of their offspring?
In a species of flowers, red flower color (R) and white flower color (W) exhibit codominance. When a plant with red flowers (RR) is crossed with a plant with white flowers (WW), what is the expected phenotype and genotype of their offspring?
In a species of snapdragon flowers, flower color is determined by two alleles: R (red) and W (white). These alleles exhibit incomplete dominance, meaning the heterozygous genotype results in a blend of the two colors. What will be the flower color of a plant with the genotype RW?
