<h2> 1/2</h2>
Explanation:
Given;
Cross between a wild type stain of Neurospora and mutant stain.
Wild type can grow on minimal medium too.
Mutant strain is defective in synthesis of tryptophane amino acid. So, mutant strain can grow only in complete medium, and it can not grow on minimal medium, while wild type can grow in both mediums.
So after crossing both stains, half spores get defective gene while half get normal gene, so 1/2 or 50% proportion can grow on minimal medium.
