Answer:
Option A, B, and C are correct
Explanation:
Incomplete dominance means that the trait represented by two alleles expresses themselves equally thereby hindering dominance of any of the allele completely.
Now,
Let us assume the allele of red petals be represented by "R" and the allele of white petals be represented by "r"
The pink flowers will have genotype "Rr"
Now if two pink flowers are crossed, the following offsprings are produced
Rr X Rr
RR, Rr, Rr, rr
Let us evaluate all the options one by one
a) Ration of pink flower to red flower ( Rr:RR)
There are 2 pink (Rr) flower and 1 Red (RR) , thus the ration of pink flower to red flower is 2:1. Option A is correct
b) one out of four offspring is white in color, therefore the % of white flower is
%. Option B is correct
c) Two pairs RR and rr are homozygous, thus out of four offsprings two are homozygous. Therefore %of homozygous flowers will be
%. Option C is correct
d) There are two heterozygous offsprings i.e Rr, therefore the % of heterozygous is %. Option D is incorrect
e) half of the flowers are hybrid. Therefore option e is incorrect
Therefore, Option A, B, and C are correct
Answer & explanation:
A confidence interval is an estimated range of a parameter of interest. Confidence intervals are used to indicate the reliability of an estimate. For example, a confidence interval can be used to describe how reliable a search result is.
In other words, a high confidence interval Z value implies that a survey is more likely to indicate the actual values being presented.
In biostatistics, for example, the Z value can be used in calculations to assess the prevalence of a particular disease and the factors associated with it in a population.
The value of Z, however, is not used as a percentage (like the 99.5% addressed in this question) for calculations. A universal table is used to convert Z values and use them in statistical calculations.
Some examples of Z value conversions can be found in the table attached in this question.
