A) Which gene is sex-linked? B) What are the genotypes of each parent and each type of offspring?
Please draw Punnett Square and detail information. Thank you. I have received different answers one said there is a sex-linked gene another said no sex-linked gene.
Genotypes for parents -
A metallic blue-colored Indian blue peahen with long pinion feathers =
Dull brown-colored Indian blue peacock with short pinion feathers =
Genotypes for offspring =
Explanation / Answer
Answer - No, sex linked gene. It follows mendel independent assortment
A metallic blue-colored Indian blue peahen with long pinion feathers = BbLl
Dull brown-colored Indian blue peacock with short pinion feathers = bbll
metallic blue with short pinions - Bbll metallic blue with long pinions - BbLl
dull brown with short pinions - bbll dull brown with long pinions - bbLl
