Which processes lead to most genetic variation in sexually reproducing organisms? What are the types of natural selection? What is the difference between selection, biological fitness, and adaptations? What is a sex-linked trait? Who determines the sex of the offspring?
Organisms exhibiting genetic polymorphism often also exhibit true alternative life-history strategies in which behavioral tactics are genetically fixed. Su... Tuttle,M E. - 《Behavioral Ecology》 被引量: 274发表: 2003年 Genomic degradation of a young Y chromosome in Drosophila miranda Study of the...
Reproduction refers to the mechanisms through which living organisms generate new living organisms, or offspring. The two major types of reproduction are sexual reproduction and asexual reproduction.Answer and Explanation: Become a Study.com member to unlock this answer! Create y...
It is argued that physical complexity must increase in molecular evolution of asexual organisms in a single niche if the environment does not change, due to natural selection. It is possible that complexity decreases in co-evolving systems as well as at high mutation rates, in sexual populations...
(implies no gene flow) • Applies to fossils and asexual organisms just as well • It’s testable: species are named based on statistically significant differences 2 The trouble is…. • It takes significant time, money, and analysis to estimate phylogenies well so few have been ...
Asexual reproduction is a method of reproduction that requires only one parent. There are several ways that asexual reproduction...
What is Asexual Reproduction Asexual reproduction in living organisms is the making of their offspring (young ones) from the cell of only one parent without the need for the opposite gender. Reproduction ensures that living organisms are maintained so that as older ones die, new offsprings are ...
Identify the type of asexual reproduction described. An organism grows back a lost body part. Unequal division of cytoplasm. Specialized cells are released and eventually develop into a new organisms that are identical to the parent. Asexual reproduction in plants. ...
In short: There is no asexual “type”. A Misunderstood Orientation Many people hear the word “asexual” and make assumptions about what it means. They think of single-celled organisms in a petri dish. They think of a celibate monk on far off mountaintop. They think of a genderless robot...
than the previous characteristic, i assure you)~Identity ~grow and develop at some point in their lives ~create/reproduce organisms similar to themselves Also has two kinds: Asexual & Sexual Reproduction ~communicate with organisms similar to themselves ~move under their own power....
