Ok, well the first thing you should do is create a key. Since the deep fried chimichangas are dominant to the baked ones, their alleles will be BB (homozygous, meaning the same) and Bb (heterozygous, meaning different). These two alleles, BB and Bb, are dominant. Now, since the baked chimichangas are recessive, their alleles will be bb (homozygous because they're the same, both two little b's). Since the question stated that a homozygous deep fried chimichanga crossed with a homozygous baked one, we're going to use the BB allele for the deep fried and the bb allele for the baked. After inserting them into your punnett square and doing some crossing over, your end result in all the boxes will be Bb. This means that 100% of the result will be heterozygous deep fried chimichangas. Hope this helped some! :)
