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: F$_1$ progeny exhibits complete dominance, showing the dominant flower color. Antirrhinum: F$_1$ progeny exhibits incomplete dominance, resulting in an intermediate flower color (e.g., pink when red and white are crossed).
