What do you conclude from this information?
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.
