Jabba the Hutt has finally decided to settle down and have a family. He has undergone genetic testing and learned that he is heterozygous for Hutt Fungal Syndrome, which is caused by recessive alleles. He is worried that his children might suffer from this syndrome. His Hutt mate has undergone genetic testing and discovered she is homozygous dominant for the syndrome. Should Jabba be worried?

• Yes
• No
