HELP!!!! Restriction maps illustrate the lengths of DNA fragments between restriction sites. Which of the following information

Which of the following is a accurate depiction of primary ecological succession?
Jlenok [28]

Answer:

This question lacks options, however, primary succession will be explained for detailed comprehension.

Explanation:

Ecological succession is the gradual series of changes that occurs in an ecosystem, charging it's structure and composition over time. It is of two types namely; primary and secondary successions.

Primary succession is characterized by the "LACK OF NO SOIL". It begins on a barren piece of land e.g rocks, with no form of life previously known to colonize the area. In primary succession, the barren land is first colonized by organisms such as lichens etc., which are collectively regarded to as PIONEER SPECIES.

The dominant allele is for black fur. The recessive allele is for white fur.
Leokris [45]

Answer:

FF , Black fur.

ff, white fur.

Explanation:

Genotype may be defined as the genetic constitution of the organism whereas phenotype depends on the genotype for the physical expression of the trait.

Let the genotype of the dominant fur (black ) be D and the genotype of white fur (recessive)  is f. homozygous means the individual should have the same allele for the trait. A mouse with homozygous dominant has genotype FF . This mouse has black fur. A mouse homozygous for the recessive trait has the genotype f. This mouse has white fur.

Thus, the answer is FF , Black fur.

ff, white fur.
