Birds such as Agapornis pallid fischeri are born with red eyes, which will generally transform into their normal eye color as they mature. some are in the state of having retained red-pupils while illuminated by flash for instance. However, there is a reflection of light from Ino’s. That little explanation of pallid
Agapornis mutation in roseicollis.
Phenotype Pallid Fischer
Pallid Fischeri Feathers:
Melanin reduces in all feathers; thus, it seems to shed green under the green series and will appear to fade blue under the blue series. it usually still leaves a trail on the outside wing portion.
Pallid Fischeri eyes:
Pallid fischeri eyes have normal colored eyes with sufficient light, while they take a scarlet red upon a pupil and their irises appear in a deep red. the pale mutation of roseicollis Agapornis is almost like this one in pale closeness.
Pallid Fischeri legs:
These are pallid fischeri – which possess red fleshly legs and a white nail. It almost seems as if it is a mutated/fallow foot.
Mode of Inheritance for Pallid Mutation:
Fischer’s Lovebird, as a carrier of the Pallid mutation, shows a sex-linked recessive inheritance pattern. The Pallid trait being genetically inherited in this manner indicates that the specific gene responsible for it lies on the X-chromosome of the sex linkage. This kind of gene usually has a linkage with X chromosomes.
Since males carry only one X and one Y chromosomes, if they inherit a copy of “P” gene, then they express Pallid phenotype.
The female lovebird has two X chromosomes, but it must inherit the Pallid allele in both X chromosomes to be Pallid. Should they inherit Pallid alleles in the female chromosomes alone, they would only become carriers of the mutation and not the associated character trait.
