Question

With reference to flower color, two independent crosses were made, one between true breeding garden pea plants and another between true breeding Antirrhinum plants. Write the phenotypes of their F$_1$ progeny. Justify your answer giving reasons.

Hint:

Inheritance patterns differ between species: Garden pea shows Mendelian dominance, while Antirrhinum shows incomplete dominance.

Answer 1

Garden Pea: The F$_1$ generation displays complete dominance, exhibiting the dominant flower color. Antirrhinum: The F$_1$ generation demonstrates incomplete dominance, producing an intermediate flower color (e.g., pink from a red and white cross).
