In this cross the trait of long tail fins is associated with the “Y” chromosome of the male.
Thus the alleles of the male are represented by XY” where X chromosome has no trait of long tails find
And the allels of the female are represented by XX, as they do not have long tail fins.
When these two are crossed , the following punnet square is produced
X Y”
X X X X Y”
X X X X Y”
The XX is the female while the XY” is the male offspring.
I believe it would be the reptile kingdom!

Answer:
Most likely diagnosis is Basal Cell Carcinoma (BCC), most likely caused by years of prolonged exposure to sunlight over time.
Explanation:
Basal Cell Carcinoma (BCC) is a common type of skin cancer that develops when the basal cells that is responsible for producing new skin cells when they die, become mutated and causes the basal cell to abnormally multiply rapidly and continues to grow. The accumulation of these abnormal cells is what results in cancerous tumors that appears like ulcers on the skin. Prolong and intense exposure to the ultraviolet (UV) radiation from sunlight has been linked to the most likely cause for the mutation of the DNA in the basal cells which leads the abnormal cell growth and multiplication. People who expose themselves to the radiation of the sun for longer periods, over time, are at high risk of developing this cancer.
