Answer:
Polygenic inheritance
Explanation:
Polygenic inheritance occurs when a genetic trait is regulated by more than one genes. All the alleles of these genes together determine the phenotype of the organism for the polygenic trait. Here, the phenotype is regulated by the total number of dominant alleles for all the genes that regulate a polygene trait.
For example, human skin color is a polygenic trait. The final phenotype depends on the total number of dominant alleles of all the genes that regulate the skin color in human.
I honestly think it’s the second one
Sorry if I’m wrong
The allele combination for a female carrier is XRXr
Answer:
amount of copper
Explanation:
<em>The independent variable would be the amount of copper fed into the experimental rats.</em>
An independent variable during an experiment is a variable whose value is not dependent on any other variable being measured in the experiment.
The value of an independent variable is not changed by any other variable in an experiment. In actual fact, the effect of the independent variable is being tested on other variables (dependent variables) in the experiment.
<u>Hence, in an experimental study of the effect of copper deficiency on coat color in rats, the amount of copper fed into the system of the rats will be varied and the effects of this variation on the coat color of the rats would be observed by measuring relevant variables. Therefore, the amount of copper is the independent variable.</u>
Before the eukaryotic cell can go to the G1 phase to S
phase, it must first, grow. It is necessary for the eukaryotic cell to grow and
do this in order to prepare itself before undergoing the replication of DNA.
