Comments on Transferring Color Mutants to other Species

As I stated previously - I used a co-dominate color gene found in the Ringneck Dove (Streptopelia risoria) in my three projects. This means an offspring of the desired co-dominate color can be produced in the F1 young. The known results of 4 possible phenotypes (color mutations: Tangerine, Blond, Orange & Pearled) intrigued me. 

Using the sex-linked colors, Blond (dilute) & White (extreme dilute) can reduce the number of steps to obtain good results compared to the transferring of the other known recessive color mutant genes. Using a Blond or White Ringneck male would be the best pairing and any visual mutant young will be female & with luck these may be fertile

My first hybrid project entailed working with the Eurasian Collared Dove & producing a Tangerine ECD. During this project I produced Blond, Pied, Rosy and Peach ECD along with the Tangerine, Orange & Pearled ECD. In the ECD project the F1a; F2a, F3a etc. visual recessive colored hybrids proved quite fertile. I account for this fertility because both species are within the same group of "ring-necked species"; whereas the three others in my projects; although they are in the Streptopelia genus they are not considered a "ring-necked species".
(Read the ECD Article)

 ( I denote the "a" after the F1, F2 F3 etc; as the pairing of these hybrids together to obtain a visually recessive colored bird & proceed to the next step, this maybe incorrect in symbol etiquette, but this is how I do it. I also use W to signify the wild type colored of the desired species host)

The following is my comments of the steps which would be involved in trying to transfer a known recessive color gene into the Senegal, Laceneck or Dwarf Turtle Doves. These statements are taken from my ECD project & can be applied to any such project & I assume will work the same. I know that in such a project, the length of time to obtain the end result of each step increases with the added breeding steps to obtain the visual color mutant hybrid before proceeding. I do not know these such hybrid's blood percentages that would be calculated for each added step to obtain the desired visual bird. See below on how I view it.

Example: Ivory Ringneck to Senegal (normal color) = F1 young
(you can replace Senegal with either Laceneck or Dwarf Turtle)

F1 = all young are 1/2 % of each parent, are wild type in color (variable) & carry the "ivory" color gene hidden
       You then must pair two F1 offspring together to obtain a visual Ivory hybrid (blood purity percentages ?)
       F1 + F1 = F1a (desired visual color)

F1a Ivory colored hybrid paired to pure Senegal to produce F2 young
       F1a + W = F2
       F2 = all young are wild colored & all carry the "ivory" color gene
      You then must pair two F2 young together to obtain a visual Ivory hybrid (blood percentage ?)
      F2 + F2 = F2a (desired visual color)

F2a Ivory colored hybrid paired to pure Senegal to produce F3 young
F2a = F2a + W = W = F3
F3 = all young are wild color & all carry the "ivory" gene (blood percentage purity ?)
F3 + F3 = F3a (desired visual color)

F3a Ivory colored hybrid paired to pure Senegal to produce F4 young
F3a + W = F4
F4 = all young are wild color & all carry the "ivory" gene (blood percentage purity ?)
F4 + F4 = F4a (desired visual color)

Keep following these steps until you produce a visual offspring which is undistinguishable from the pure bird (including the voice). With the possible variances due to breeding the sibling hybrids together the process may take 5 or more years to obtain the desired visual/voice results.
