likoan [24]

Answer:

d. budding

Explanation:

Budding is a type of asexual reproduction, as are binary division, multiple division, vegetative propagation, and fragmentation. This type of reproduction is observed in some species of animals and plants.

In budding, as the name suggests, sprouts appear on the surface of the organism. These shoots will give rise to a new individual, which may grow on the organism that originated it, forming the colonies, or be released into the environment.

This type of reproduction is common in several plant species, occurring more frequently in angiosperms, and also in some animal species, especially in the cnidarian and porifer group.

The recombination frequency between linked genes A and B is 40%, between B and C is 20%, between C and D is 10%, between C and A
Alja [10]

Answer:

ACDB (or BDCA)

Explanation:

The linked genes A and B have a greater frequency of recombination (40%) and therefore they are found furthest away on the chromosome. Conversely, the smaller distance is between D and B, which exhibit a lower frequency of recombination (10%), while C is localized at the same physical distance of both A and B (20%), so the physical map is ACDB.

Physical map:

A--------C-----D-----B
