You decide to analyze the inheritance of one more trait: the number of leaves per plant. You cross together two pure lines: one line with individuals growing one leaf per plant, and another line with five leaves per plant. All of the F1 progeny show five leaves per plant. You self-cross all of these F1 plants. The resulting F2 plants grow one, or five, leaves in the following numbers: 26 plants with one leaf & 77 plants with five leaves. Which one of the following options most accurately describes the likely genotype of the plants with one leaf? These plants are likely homozygous for the recessive allele for the leaf number gene. These plants are likely homozygous for the dominant allele for the leaf number gene. These plants are likely heterozygous for the leaf number gene. These plants are likely homozygous dominant or heterozygous for the leaf number gene. None of the above

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
