Answer:
The involvement of more than two genes.
Explanation:
The polygenic characteristics have many phenotypes because more than two genes governs the phenotype of individual organism. The single gene contains a pair of alleles that codes for two phenotype and two genes will code for 4 phenotype. Thus, more than two genes for example, three genes will have six phenotypes.
The skin color and height are polygenic characterstics in humans.
Answer:
The tetrad occurs during the first phase of meiosis. It is the foursome of chromatids that forms when replicated homologous chromosomes align. It must be formed for crossing over to occur. It is broken apart when the homologous chromosomes separate in meiosis I.

Answer: I chose rainforest
A rainforest is an area of tall, mostly evergreen trees and a high amount of rainfall. Mean temperatures in tropical rainforest regions are between 20 and 29 °C (68 and 84 °F), and in no month is the mean temperature below 18 °C (64 °F). The main animals are monkeys, Blue Morpho Butterfly, Okapi, Three-Toed Sloth, Jaguar, Capybara, Toucan, and Poison Dart Frog. The main plants are ferns, lichens, mosses, orchids, bromeliads, and of course many types of trees. including the rubber tree. Deforestation is a particular concern in tropical rain forests because these forests are home to much of the world's biodiversity. For example, in the Amazon around 17% of the forest has been lost in the last 50 years, mostly due to forest conversion for cattle ranching. The main cause of deforestation is agriculture (poorly planned infrastructure is emerging as a big threat too) and the main cause of forest degradation is illegal logging.
If the auto control is negative for both phases and antibody panel cells are 3 at immediate spin and negative at AHG, then a cold antibody may be present.
<h3>What is molecular testing?</h3>
Molecular testing refers to the strategies to find a given molecule in a sample (in this case antibodies).
The anti-human globulin (AHG) method is a test employed by blood banks to perform antiglobulin assessment.
In conclusion, if the auto control is negative for both phases and antibody panel cells are 3 at immediate spin and negative at AHG, then a cold antibody may be present.
