This means that for a person to have blue eyes, they must inherit two copies of the recessive allele (<strong>b<\/strong>), one from each parent.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Understanding Dominance and Recessiveness<\/strong><\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The <strong>brown eye allele (B)<\/strong> is dominant, meaning that if a person has at least one <strong>B<\/strong> allele, they will have brown eyes.<\/li>\n\n\n\n<li>The <strong>blue eye allele (b)<\/strong> is recessive, meaning that a person will only have blue eyes if they inherit two <strong>b<\/strong> alleles (<strong>bb<\/strong>), one from each parent.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Wendy\u2019s Genotype<\/strong><\/h4>\n\n\n\n<p>Since Wendy has blue eyes, she must have inherited two recessive <strong>b<\/strong> alleles, one from her mother and one from her father. This means her <strong>genotype must be bb<\/strong>.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Her Father\u2019s Genotype<\/strong><\/h4>\n\n\n\n<p>Wendy\u2019s mother has blue eyes, meaning her genotype must be <strong>bb<\/strong>, as she can only pass the <strong>b<\/strong> allele to her children.<br>Wendy\u2019s father has brown eyes, which means he could have either of the following genotypes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>BB<\/strong> (homozygous dominant)<\/li>\n\n\n\n<li><strong>Bb<\/strong> (heterozygous, meaning he carries both a dominant and a recessive allele)<\/li>\n<\/ul>\n\n\n\n<p>However, since Wendy has blue eyes (<strong>bb<\/strong>), she must have inherited a <strong>b<\/strong> allele from her father. This means her father <strong>cannot<\/strong> be <strong>BB<\/strong> because then he would only have <strong>B<\/strong> alleles to pass on. Instead, he must be <strong>Bb<\/strong>, meaning he carries one dominant allele (<strong>B<\/strong>) and one recessive allele (<strong>b<\/strong>).<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Conclusion<\/strong><\/h4>\n\n\n\n<p>For Wendy to have blue eyes, she must be <strong>bb<\/strong>.
