Detailed explanation-1: -A researcher has discovered that the reason birds learn to fly so easily is because latent memories may have been left behind by their ancestors. It is widely known that birds learn to fly through practice, gradually refining their innate ability into a finely tuned skill.
Detailed explanation-2: -Alleles and Inheritance Their feather color is specified by the more-dominant of the two alleles: ‘ash-red’ is dominant to ‘blue’, which is dominant to ‘brown’. Females have just one color allele. Whatever allele that copy is specifies their feather color.
