Answer:
Split-half Method.
Explanation:
Split half test is the method to assess the reliability of internal consistency.
Split-Half method is a reliability test in which to gain insight about a single knowledge, the test is divided into two parts. Then two groups of students or people are required to participate in the test at the same time. The scores of both the groups are assessed. A test that have high correlation suggests the reliability and will reveal how well or poorly the students will perform in the test.
<u>In the given case, Chan has divided the test questions into five questions each for two groups, to check the reliability of instrument. The results of both the test are assessed with the hope that they have similar results. This is the method of testing reliability with the split-half method</u>.
So, the correct answer is split-half method.
Answer:
RrYy x RrYy
Explanation:
Given
Round (R) allele is dominant over wrinkled allele "r"
and Yellow seed allele (Y) is dominant over green seed allele "y"
If I find a plant with round and yellow seeds and want to determine its genotype, then I will cross it with plant that has heterozygous genotype for both the characteristics i.e "RrYy"
Let us say that the plant I found is heterozygous dominant for both the traits i.e "RrYy"
If RrYy is crossed with another RrYy ,we get -
RY Ry rY ry
RY RRYY RRYy RrYY RrYy
Ry RRYy RRyy RrYy Rryy
rY RrYY RrYy rrYY rrYy
ry RrYy Rryy rrYy rryy
Thus, the possible gnotypes would be
RRYY-1
RRYy-2
RrYY-2
RrYy-4
RRyy- 1
Rryy-2
rrYY-1
rrYy-2
rryy-1
The phenotypic ration for this cross is
. This is a standard cross result between two heterozygous parents.
