When analyzing a cross involving two traits, each trait is analyzed separately, and then the frequencies of each are combined to yield the observed phenotypic ratios. Group of answer choices

The correct answer is "True".

Explanation:

The missing options of this question are "true" or "false" and in this case the correct answer is "true". According to the laws of inheritance established by Charles Darwin, the certain traits of species can be analyzed and studied by using crossing experiments. These experiments are performed first by analyzing the traits of each individual separately and second by observing the frequencies of each are combined to yield the observed phenotypic ratios. Different approaches are used to study the frequencies of each allele, and the most widely used is the punnet square approach.

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles

i believe the answer would be b. hope it : )
