I would say the second option. Because colorblindness is regressive that means that there must not be a dominant genotype that replaces colorblindness. In most people there is a dominant genotype that replaces colorblindness which is simply being able to see color. So in me for example I might have a colorblindness genotype somewhere but since it is regressive (b) then it gets taken over but the color vision (B) remember that a dominant will always take over the regressive. the only way that someone can be color blind is if there are 2 regressive (b) genotypes that means there is no dominant genotype to take them over. Brown eyes is an Example of a dominant genotype that means that it will take over blue eyes (which is why there are most brown eyed people in the world)
I chose the second option because there is both X and Y and each one has either a B or a b the last option only had B.
But Remember that B > b
B trumps b
The interphase is the stage, in which the cell is not dividing. Teh genetic material in this stage is present as chromatin and the nuclear envelop remains intact, making the appearance as a darkly stained center. the nucleolus is also visible.
The prophase is the first stage of the mitosis, at this stage the genetic material starts condensing. the nucleolus starts fading away due to its degradation. the genetic material appears condensed and starts taking the shape of the chromosomes. The nuclear envelope is degraded, which makes the visibility of the chromosome easier.
A nonrenewable resource is a resource of economic value that cannot be readily replaced by natural means on a level equal to its consumption. Most fossil fuels, such as oil, natural gas and coal are considered nonrenewable resources in that their use is not sustainable because their formation takes billions of years.
I think it’s 6
These six essential nutrients are nitrogen, phosphorus, potassium, magnesium, sulfur and calcium. The cool thing about these key nutrients is that they help create new cells, which then organize into plant tissue. Without these nutrients, growth and survival would not occur.
