Answer:
The two forms interbreed and their offspring survive and reproduce well.
Explanation:
When talking about classification of species, one of the first features observed is the species fitness, which describes the reproductive success or their ability to leave to their successive generations the most copies of their genotype. When different species that were recently divided into 2, by geographic isolation, for instance, usually there is no genetic compatibility, and if its possible to produce offspring, there might be some development issues like infertility.
Answer:
23
Explanation: By the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. The overall process of meiosis produces four daughter cells from one single parent cell. Each daughter cell is haploid, because it has half the number of chromosomes as the original parent cell.
Answer: 1.3 to 1.1 billion years.
Explanation: The oldest rocks in the New York Bight region are found in surface outcrops throughout the Highlands region. These exposures of Precambrian "basement rock" have been estimated at 1.3 to 1.1 billion years old.
Answer:
Option A, C and D
Explanation:
Mutations can be beneficial and call also not be beneficial. Examples of beneficial mutation includes laptop tolerance, HIV resistance etc. This mutations occur as changes in the nucleic acid sequences (DNA; which is made up of the four nitrogenous bases, deoxy/ribose sugar and phosphate group. Changes in these bases can bring about mutations that are beneficial) of organism and also it depends on where in the genetic code they occur. Beneficiary mutations can bring about increased fitness of the organisms involved.
