Genetic dominant means and why it makes a difference in crossbreeding animal

1 answer:

6 0

Genetically dominant means that the trait will always be dominant to the genetically recessive trait as long as the allele for that trait is present.

Let's say you have an R allele that codes for a brown coat and an r allele that codes for a white coat. Say the R allele is genetically dominant to the r allele.

If you have an animal with the genotype RR or Rr, it will show a brown coat because the genetically dominant R allele is present.

Only if the animal as a rr genotype will the white coat show because the genetically dominant R allele isn't present.

When you crossbreed, genetic dominance can be important because it can increase the chances you'll have more diverse offspring with increased chance of survival since the dominant traits, if favorable, will always show for a trait.

What happens when the temperature of air decreases to the dew point or below the dew point

svet-max [94.6K]

When the temperature of the air becomes almost equal to the dew point the air becomes saturated and the relative humidity during this condition becomes 100%. If the temperature of the air decrease below the dew point the relative humidity will be 100% or exceeds 100%. This condition, when the temperature of the air decreases below the dew point is called supersaturation but most of the time the temperature of the air will be lower than the dew point.

Which of the following is/are common to chemiosmosis and the light-dependent reactions of photosynthesis? electron transport onl

blondinia [14]

Answer:

Both electron transport and a proton gradient

Explanation:

The process of oxidative phosphorylation in mitochondria and electron transport chain in photosynthesis undergo chemiosmosis to produce ATP molecules.

Chemiosmosis is a process where the energy utilized by the movement of proton and electrons produces ATP molecules.

Both the processes involve the movement of electrons through electron carriers where the reduced energy is utilized to drive the flow of protons through the plasma membrane. This creates a proton gradient across the plasma membrane which rotates the ATP synthase and converts the ADP molecules into ATP molecules.

Thus, the selected option is correct.

solniwko [45]

Answer:

all 20

Explanation:

It is impossible to know how many individuals will have the disease at the end without knowing other factors such as the condition where the subjects are being held, trial specifications and safety measures, etc. Based on the information provided, the best prediction that can be made is that all 20 subjects will have the disease. This is because since none of them are immune the disease will spread between the patients/subjects through contact or testing equipment.
