This means that for a plant to have fuzzy leaves, it can either have the genotype FF (homozygous dominant) or Ff (heterozygous). On the other hand, a plant will only have smooth leaves if it is homozygous recessive, with the genotype ff.<\/p>\n\n\n\n<p>Let\u2019s examine each of the crosses provided:<\/p>\n\n\n\n<p><strong>A. ff x ff<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Both parents have the genotype ff, which means they both have smooth leaves.<\/li>\n\n\n\n<li>Since both alleles are recessive, all offspring from this cross will inherit an f allele from each parent, resulting in the genotype ff.<\/li>\n\n\n\n<li>Therefore, all offspring will have smooth leaves.<\/li>\n<\/ul>\n\n\n\n<p><strong>B.
