A major long term objective is to establish pure single mutant lines. The other major objective is to continue studies of the tangerine and tangerine modifier gene.

Tangerine Pearled Minimal Cock (17) X Tangerine Pearled Minimal Hen (1666)

D+dB +pi +ry TaTa M+ D+ +pi +ry TaTa M+

Objective: To produce tangerine with white neck ring and white flights. This is a father/daughter pair. Also, a test to determine if the male is rosy tangerine (if so, half of offspring will be rosy tangerine).

This pair has produced eight offspring since August of 2007

A 1-2-1 ratio would be expected at the modifier locus if both parents are M+ at that locus. These results show both the male and female parents to be M+ at the modifier locus. Also, they show both parents to be heterozygous rosy.

Pearl Pied Cock (1643) X Tangerine Pearled Hen (1783)

D+D+ pipi ?ry TaTa M+ D+ ?pi TaTa M+

Objective: To test for pied in the hen (the vivid rusty red color may indicate the hen carries pied). Also testing modifier gene. This is a sibling pair. The hen is a true tangerine and the male may carry rosy. Offspring will be true tangerine.

Results through June 30, 2008

This healthy hen was found dead on the floor of the cage on 02/24/2008. I attribute death to night fright and broken neck from hitting the top of the cage. Results are limited to one clutch. This is quite a disappointment because some offspring from this pair would be true tangerine.

These results indicate that the male is heterozygous rosy. The hen was a true tangerine. From these results one can reach no conclusions on the genotype of the male at the Modifier locus. The Solid Tangerine is a solid colored tangerine with white flights and white neckring with rosy breast, neck and head. There is a slight tangerine suffusion on the rosy head. This is indicative of heterozygous rosy in tangerine birds. The tangerine pearled offspring as of now shows no presence of rosy and may be a true tangerine.

Objective: This hen is a pearled heterozygous tangerine. This means that she is homozygous at the modifier locus. Paired to this male carrying no modifier genes all offspring should be M+. That means that all homozygous tangerine will be pearled and no pearled heterozygous tangerine should be produced. Because the hen carries pied hidden this will also test for pied in the male. Should rosy tangerine be produced I will know that the hen also carries rosy.

The cock obviously carries rosy hidden and is not a pure Show Ivory. I will keep the pair together because of the production of the unidentifiable offspring to see if I can produce another or determine the color of 1281. This pair should only produce either blond or peach offspring.

Objective: To produce large offspring and test inheritability of body weight. The cock weighed 200 grams at 3 months of age and the hen weighed 195 grams. Also, both the hen and cock carry rosy, so this will allow the production of some rosy tangerine offspring and some homozygous rosy ash offspring. This should allow observation of color differences between ash and rosy ash.
