Introduction: The cross of Tim and Jan was analyzed to study the transfer of the genetic trait freckles in children, which is a dominant trait in the F1 generation. The heterozygous state of the parents with freckles will be Ff. The cross will take place between Ff x Ff to give rise to the progeny.
