Answer:
Explained
Explanation:
Concordance: This is a term used in genetics. This term is used to imply the presence of the same trait/characteristic in both the members of a pair of twins.
Twins can be of 2 types. They are monozygotic twins and Dizygotic twins.Monozygotic twins are identical twins, i.e. they are formed from one zygote that later splits into two forming two embryos.
Dizygotic twins are non-identical twins or fraternal twins formed from the fertilization of two different eggs with two different sperm cells.
Concordance values can be calculated as:
C = Number of concordance pairs/(number of concordant pairs + number of discordant pairs)
Monozygotic twins generally have a concordance value of 44% for a specific trait.
Dizygotic twins have a concordance value of less than 5 % for a trait.
For identical twins the number of concordant pairs would be 50 out of 100.concordant pair would be
For non-identical twins, the number of concordant pair would be 17 out of 100.
For a recessive trait to be expressed, both the parents should be heterozygous for that trait.
Answer:
consumer, worker, and citizen
Answer:
The forces that move pieces of Earth's surface and create new landforms very rapidly is described below in detail.
Explanation:
The Earth's surface is continually developing through forces in the earth. The everyday processes of land movement, wind, and precipitation appear in variations to landforms over a prolonged period of time. Driving energies incorporate earthquakes, volcanoes, and erosion. People also commit to variations in the appearance of land.
Answer:
downward communication
Explanation:
Downward communication in organization refers to communication that flows downwards, that is from higher levels/level in the organization( vice president for example) to lower level/levels in the organization. This is demonstrated here where the vice president disseminates a five-year strategic plan to the deans and department heads who are his subordinates in the organization(university here)
