Summary Introduction

To explain: The leaf variegation in Mirabilis jalapa.

Introduction: Non-mendelian inheritance involves the transmission of cytoplasmic or extra-nuclear genes. This type of inheritance pattern is known as extra-nuclear inheritance, where only a single parent contributes.

Summary Introduction

To explain: The phenotypes of progeny associated with the cross between variegated ♀ × green ♂.

Introduction: The difference in the leaf color of Mirabilis Jalapa is due to the presence of either green or colorless (white) chloroplast.

Summary Introduction

To explain: The phenotypes of progeny associated with the reciprocal cross between green female ♀ and variegated males ♂.

Introduction: The role of parental sex in trait inheritance can be determined using a reciprocal cross. This type of cross also reveals whether the trait is autosomal or sex-linked.

There are some members of the genus Datura that are trisomic for the chromosome set, which carries the genes for purple (p+) and white (p) flower color. In a cross involving a trisomic p+ p+ p female and pollen from a normal p+ p plant, what is the expected proportion of purple and white flowered individuals?
Consider this four-factor cross: Tt Rr yy Aa × Tt RR Yy aa, whereT = tall, t = dwarf, R = round, r = wrinkled, Y = yellow, y = green,A = axial, a = terminal. What is the probability that the first three plantswill have round seeds? What is the easiest way to solve this problem?
Consider this cross in pea plants: Tt Rr yy Aa × Tt rr Yy Aa, whereT = tall, t = dwarf, R = round, r = wrinkled, Y = yellow, y = green,A = axial, a = terminal. What is the expected phenotypic outcomeof this cross? Have one group of students solve this problem bymaking one big Punnett square, and have another group solve it bymaking four single-gene Punnett squares and using the multiplication method. Time each other to see who gets done first.
