Question

Which one of the following options correctly represents the type of life cycle patterns?

1 2 3

• A. 1⇒ Diplontic, 2⇒Haplo - Diplontic, 3 ⇒ Haplontic
• B. 1⇒ Diplontic, 2⇒Haplontic, 3 ⇒ Haplo - Diplontic
• C. 1⇒ Haplo- diplontic, 2⇒Haplontic, 3 ⇒Diplontic
• D. 1⇒ Haplontic, 2⇒Diplontic, 3 ⇒Haplo- diplontic

Answer 1

The correct option is B

1⇒ Diplontic, 2⇒Haplontic, 3 ⇒ Haplo - Diplontic

1 is Diplontic as life cycle has dominant diploid sporophyte stage.

2 is Haplontic as life cycle has dominant haploid gametophyte stage.

3 is Haplodiplontic as life cycle is equally dominated by gametophyte and sporophyte stages.
