You discover a gene that results in a complete lack of hair in rats, and you name the gene "chromedome." A cross of homozygous normal and homozygous bald rats results in all bald rats. You conclude that the baldness allele is dominant, but when you repeat the cross with different rats none of the offspring are bald. Extremely puzzled you study your records and discover that in the first cross the bald rat was female, while in the second cross the bald rat was male. What do you conclude from this information?
A. Chromedome is imprinted in females. B. Chromedome is imprinted in males. C. Chromedome is dominant in females and recessive in males. D. Chromedome is dominant in males and recessive in females. E. Chromedome is an X-linked gene.
