Mothers & Daughters!

[70%cocoa]

Mothers have one dose of blue and daughters have two. Eyeline removed in the daughters.

Mothers are equivalent of Apricot Mallards? But with one dose of M only? Father basically same as Khaki Campbell but with one dose of blue?

Hi & thanks for thoughts

Yes, the "daughter" pair of ducks had a Khaki Campbell father & Khakis are dark phase duskies plus brown dilution. The "mother" pair of ducks were bred from a Saxony drake (light phase wild-type mallard plus two doses of blue), & a dark dusky duck (believed to be hetero dark/light phase, pure for dusky).

Duckyfromoz, I guess you could say that both mothers & daughters are bi-products of a program to develop Blue & Apricot Campbells. And yes, I have found the same with the four ducklings bred (two boys & two girls), ie, boys dark & girls light; you will need to look past the blue in three of the ducklings in following photo:-

70%cocoa, yes, the mothers both have one dose of blue inherited from their saxony father; they are M+/m^d (M+ from Saxony & m^d from dark dusky), Li+/li (li from Saxony & Li+ from dark dusky duck), & Bl/bl+ (blue from Saxony & no blue from dark dusky duck).

The father of the daughters as mentioned is a pure khaki Campbell so no blue from him. If I hadn't bred these & known what has gone into them I too would have thought the daughters to be pure for blue dilution (Bl/Bl), but they each only have one dose (Bl/bl+). All four ducklings inherited one dose of sex-linked brown dilution from the Khaki Campbell father, but as you know, only the daughters will express influence in one dose (hemizygous). Of the four ducklings produced only one, the dark dusky drakelet, didn't inherit blue & the one dose of sex-linked brown he & his blue brother inherited from their father didn't express. The two daughter birds, both of which inherited one dose of blue (mother) & brown (father) dilution have expressed same & are extra diluted as a result.

The daughters do have facial markings, but only very faint in one of them (best seen in them as young ducklings pic below)? As an adult, the bird with faint facial markings (front bird daughter photo first post) is from memory also full pigmented underwing? These ducklings could be genetically either M+/m^d, or m^d/m^d & I have assumed all but one (dark dusky m^d/m^d) to be M+/m^d but is this really so with one of the girls?

Middle duckling very faint facial markings, other two clear facial markings, two light are the girls, dark dusky hidden

One other point; if you look @ the two daughter ducks as adults & consider the dilutions they have (hetero blue & hemi brown) then you may note that it is the blue that we see & not the brown (except partially in speculum of rear pictured daughter duck?). Although both dilutions combined make for a lighter bird, blue appears to be largely epistatic & what we see when in combination with sex-linked brown!

As juveniles, pics not too great but they didn't like photos
