In horses, coat color is inherited codominantly. There is an allele for chestnut color coat and an allele for white coat. Heterozygotes are termed "roan" and have a redish appearance due
to a expressing both chestnut and white hairs. If tall horses are dominant to short horses,
then what are chances have 2 roan horses both heterozygous for tall height having
offspring that are white and short?

Monarch butterflies have brightly colored orange wings with black patterns on them, making them easily visible to birds that eat butterflies and moths, yet birds rarely eat the monarchs. likewise, the monarch caterpillars are brightly striped yellow and white and black, and they also are rarely eaten by birds, although some wasps will attack them and feed them to their young. what can be inferred from these observations? monarchs must threaten and attack birds, but not wasps. monarchs have a way of discouraging bird predation that does not involve hiding. monarchs’ wings are so colorful that most birds must find them difficult to eat. monarchs lay more eggs than other less conspicuous butterflies.
