One of the most popular birds, either cage or aviary, anywhere in the world is the canary. These delightful little birds are now available in a huge array of color and shape variations. Canaries are ideal as both pets and for serious breeders or exhibitors.
I have a puzzling question to ask any knowledgeable canary enthusiast.
Which of the following traits will be exhibited in an offspring by the pairing of a recessive white hen that has red eyes with a recessive white male that has red eyes?
* (a) 100% white recessive the eye color RED
* (b) 100% white recessive with normal eyes
* (c) 50% recessive white with RED eyes and 50% recessive white with normal eyes
* (d) All of the above
The correct answer is (d) All of the above.
Here are the facts:
Eyes that are red are produced by two different factors.
1. SATINET, a recessive sex link factor and
2. INO, a somatic recessive factor
(a.) To obtain 100% White recessive with eyes that are red, you would pair a the white recessive male with red color eyes with a white recessive hen with red eyes. Both members of the pair are either SATINET or both INO.
(b) To obtain recessive white with normal (black) eyes, pair a recessive white male with red eyes (INO) with a recessive white hen with red eyes (SATINET). The male has the trait from a somatic chromosome while the female has the trait from a recessive SEX LINK chromosome. They are not homologous and not in the same chromosome so they cannot exhibit red eyes. They will have BLACK EYES.
100% of the offspring will be carriers of the INO factor. The males will also be split to SATINET.
(c) If you pair a white recessive SATINET male to a recessive white INO hen, as the SATINET is a recessive sex link trait and the INO is a somatic trait, all females will inherit the SATINET trait in the X chromosome. The females will exhibit red eyes and the males will be SATINET carriers with black eyes. 100% of offspring (males and females) will carry the INO trait.
