Biology
1 answer:
Vlada [557]2 years ago

Answer:

Ecological succession happens when new life takes over an environment. ... Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. The first inhabitants are lichens or plants—those that can survive in such an environment

Ecological restoration aims to recreate, initiate, or accelerate the recovery of an ecosystem that has been disturbed. Disturbances are environmental changes that alter ecosystem structure and function. Common disturbances include logging, damming rivers, intense grazing, hurricanes, floods, and fire

Secondary succession is usually faster than primary succession because soil and nutrients are already present due to 'normalization' by previous pioneer species, and because roots, seeds and other biotic organisms may still be present within the substrate

Independent assortment occurs only in cells that are heterozygous for two genes (AaBb) and not in cells that are completely homo
fomenos

Answer:

False

Explanation:

Gregor Mendel, who was referred to as the FATHER OF GENETICS, discovered the principles that governs heredity. One of those principles which he called LAW OF INDEPENDENT ASSORTMENT states that the alleles of a gene randomly segregates into gametes independently of the alleles of another gene. This means that during gamete formation (meiosis), the separation of the alleles of one gene doesn't affect the separation of the alleles of another gene.

Mendel discovered this principle when he worked with two genes that was responsible for two distinct characters. Hence, in a cell that contains two genes responsible for two different characters in the organism, independent assortment will always occur during gamete formation. Although, in an organism that is homozygous for both traits (AABB or aabb), only one type of allelic combination will be produced in the gamete. However, the alleles will still randomly align and separate independently of one another during Metaphase and Anaphase stages of meiosis.
