The pedigree chart are used to check the mode of inheritance of certain trait.
Explanation:
The pedigree is used to know the probability of the offspring getting a particular disorder or condition. It also help to discover the location of the defected gene. And through it can also be predicted that weather it will be a dominant or a recessive trait. For this pedigree data of several generations are required. Here, the phenotype ratios of the offspring can be accurately determined only when the genotypes of the parents are known.
The bird's eye contains a nictitating membrane which is a translucent, semitransparent inner eyelid. It sweeps across the surface of the eye enabling the bird to blink without losing sight of or without blocking their view.
Birds also have two different tear glands. One type of tear gland is located along the lower eyelid while the other is located at the base of the nictitating membrane. The second tear gland lubricates the bird's eyes whenever the nictitating membrane blinks.
