A punnet square can be described as a diagram which is made to predict the genotype as well as the phenotypes of the offsprings of a cross.
To study the epistatis nature of the pigmentation in bear, a punnet square was made and the results of the punnet square are shown above.
The results of the punnet square show that the cross between two bears will have the chances of producing 9/16 black bears, 3/16 brown bears and 4/16 white bears.
Chloroplast is the cell structure that enables the process of photosynthesis
The correct answer is stabilising selection. This is selection that favours an average trait value. It is thought that this sort of selection is very common as traits among most animals do not appear to change drastically over time. Stabilising selection selects against the extreme traits, and leads to a decrease in genetic diversity by favouring the average phenotypes.
Gametes are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each
