<span>The answer is 1/8. Let's separate two traits. We have two events occurring together so using multiplication rule we will multiply probabilities of those events. Event 1: the probability that the offspring will show Yy genotype. In the cross of parents Yy and Yy, one of four offspring will have YY genotype, two of four offspring will have Yy genotype, and one of four offspring will have yy genotype. Thus, the probability that the offspring will show Yy genotype is 2/4. Event 2: the probability that the offspring will show TT genotype. In the cross of parents Tt and Tt, one of four offspring will have TT genotype, two of four offspring will have Tt genotype, and one of four offspring will have tt genotype. Thus, the probability that the offspring will show TT genotype is 1/4. Hence, the probability that the offspring will show YyTT genotype is: 2/4 * 1/4 = 2/16 = 1/8.</span>
Explanation:
Make an observation about a phenomenon (qualitative and/or quantitative)
Ask a research question.
Hypothesize a possible answer for your question.
Create a procedure to test your hypothesis.
Identify what you are testing.
Identify your control group/experimental group.
Echinoderm is the name given to a member of the phylum Echinodermata. They have radial symmetry and this includes sea urchins, sand dollars, sea stars and sea cucumbers. It is suggested that they are related to the chordates which is the answer.
Their movement organs. I think it must be answer
