Genes in DNA or responsible for the traits an organism has. This is caused by Dominant and Recessive Traits. Remember that Genotypes are the genetic letters such as RR, Rr, and rr. Phenotype is physical traits.
Dominant Traits are more likely or always show in the offspring. The Dominant Genotype uses Capital letters such as RR.
Recessive Traits are less likely to show up. Their Genotype use lower case such as rr. Now genotypes of Rr have one dominant trait and one recessive trait. If the dominant trait was black fur and the recessive white fur, the offspring will be black fur because dominant traits overpower the other.
To understand how to know if an organism will have Dominant or Recessive Genes, you have to use something called a Punnet Square. Lets imagine 2 parents both have the genotype Rr. R is Black fur and r is white fur. As you can see from the chart, 3 of 4 boxes have Rr and 1 rr. Since there is a Dominant Trait with a Recessive, they will show a Dominant Phenotype, or Black fur. This has 3/4 chance and a 1/4 chance for white fur in the offspring.

Answer: B
Explanation: The amount of salt in the inner circle is equal to the amount of salt in the outer circle.
The basis of classification of
Linnaeus’ system is sexual reproduction. The
only "natural" taxon in Linnaeus' system is the species. Species defined
as a population with viable, fertile reproduction are separated from
interbreeding with other species.
4 protons, 5 neutrons, 4 electrons
The answer
is Up-regulation. One
of the best description of the process of up-regulation is an Increase
the number of surface receptors. Acts as
transcribing factor and binds to DNA, activating a gene. From binding to DNA
before a hormone binds to the receptor.
