Which type of cleavage pattern is characteristic of deuterosomes, such as echinoderms and chordates?

Deuterostomes exhibit indeterminate cleavage, where each blastomere retains the ability to develop into a complete organism, leading to identical twins in some cases.

What term describes the evolutionary process by which two species gradually develop adaptations that allow them to coexist and reduce competition for resources?

Coevolution refers to the reciprocal evolutionary changes in interacting species, often leading to specialized adaptations that reduce competition.

What is the primary mode of transmission for the fungal pathogen causing powdery mildew in plants?

Powdery mildew fungi release airborne spores that spread the disease to nearby plants, making it a common mode of transmission in many plant species.

In which ecological biome would you expect to find plants adapted to periodic flooding and anaerobic soil conditions?

Wetlands, including marshes and swamps, often experience periodic flooding and have anaerobic soil conditions, leading to the adaptation of specific plant species.

In a dihybrid cross between two pea plants (TtRr x TtRr), what is the probability of obtaining an offspring that is homozygous recessive for both traits?

In a dihybrid cross, the probability of obtaining a homozygous recessive offspring for both traits is 1/4 for each trait, so the combined probability is (1/4) * (1/4) = 1/16.
