Biology

Alexxx [7]3 years ago

Answer:

-A single gene can influence multiple traits.

-A single trait can be controlled by multiple genes.

Explanation:

1. A single gene influences two or more phenotypic traits known as a pleiotropic gene.  Pleiotropy is common in the genetics of complex disease.

Example: Phenylketonuria

It is an inherited disorder in which the level of phenylalanine is increased in the human body. This is happening because of the defect in a single gene on chromosome 12 that codes for phenylalanine hydroxylase (enzyme). This enzyme affects multiple system e.g.,  nervous and integumentary systems.

2. A polygenic trait is one whose phenotype is influenced by more than one gene. Polygenic traits are also controlled by environmental factors.

Example: Height, Skin color

These traits show continuous distribution because they are also controlled by many different genes. Epigenetics and environmental factors are also involves.

Mandalian (inherited) traits are controlled by different genes.

Arrange the events in the correct order to describe how the magnetic field forms around Earth.
horsena [70]
The correct sequence of events is : C,D,B,A.
Iron rich magma in the earth's core heats up because of radiation and the pressure exerted by the other layers of the earth. This heat in the crust trigger convection currents in the mantle. The magma closest to the core will be hotter and therefore less dense than other layers. Being less dense the layer will rise towards the crust, eventually becoming cooler and sinking back down in a circular motion.
The continued circular motion creates electric currents which then generates the magnetic field.

Why does ice cause water vapor to condense?
Ksenya-84 [330]

Answer:

Once water vapor is in the atmosphere, low temperatures cause the vapor to either condense into a liquid or undergo deposition to form ice crystals. Water droplets can form clouds from the atmosphere.

I hope this helped!
