Answer: c. The positive control tube receives any genomic DNA from a student's sample that is predicted to be infected with Wolbachia.
Explanation:
Positive PCR control can be defined as the control sample that is used as a benchmark for comparison with the results of the PCR or polymerase chain reaction. It comprises of artificial genome or primers. For amplification of microbial DNA synthetic oligonucleotides are used as targets of each primer and a hydrolysis probe is also used. As it is already known that primer as well as hydrolysis probe has the specificity for the DNA strand so it will help in identification of the specific region or sequence in the DNA structure. Wolbachia DNA can be detected if the positive control consists of samples of students affected by Wolbachia that can give indication of whether the Wolbachia species is the same as that of the one which has caused infection.

A. it has less oxygen
B. it has more oxygen
Answer:
B
Explanation:
It has more oxygen blood different after it is pumped through the capillaries in the intestines. Thus the correct option is A.
What is capillaries?Capillaries are delicate blood vessels that exist throughout body. They transport blood, nutrients and oxygen to cells in your organs and body systems. Capillaries are the smallest blood vessels in your vascular system.
Nutrients are absorbed then it goes into the bloodstream through capillaries. These nutrients include acids, vitamins and fatty acids.

In tomatoes, red fruit color is dominant to yellow. Round-shaped fruit is dominant to pearshaped fruit. Tall vine is dominant to dwarf vine.
a. Suppose you cross a true-breeding tall plant bearing red round fruit with a true-breeding dwarf plant bearing yellow pear-shaped fruit. Predict the appearance of the generation.
b. Assuming that the genes controlling the three traits are on three different pairs of chromosomes, what are the possible genotypes in the generation?
c. What are the expected phenotypic ratios?
Answer:
a) Al the offspring will have genotype - TtRrOo
b) Al the offspring will have genotype - TtRrOo
c) Tall, Red and Round
Explanation:
Given -
Red color of fruit is dominant to yellow color of fruit.
Round shape of fruit is dominant to pear shape of fruit
Also, Tall vine is dominant to dwarf vine
Crossing - true-breeding tall plant bearing red round fruit (TTRROO) * true-breeding dwarf plant bearing yellow pear-shaped fruit (ttrroo)
a) Al the offspring will have genotype - TtRrOo
b) Al the offspring will have genotype - TtRrOo
c) Tall, Red and Round

1. 7. The ability to taste the chemical PTC is determined by a single gene in humans with the ability to taste given by the dominant allele T and inability to taste by the recessive allele t. Suppose two heterozygous tasters (Tt) have a large family. Predict the proportion of their children who will be tasters and nontasters. What is the likelihood that their first child will be a taster
Answer:
3/4 taster; 1/4 non-taster
The likelihood that their first child will be a taster: 75 %
Explanation:
Complete dominance occurs when a dominant gene variant or 'allele' completely masks the expression of the recessive allele in heterozygous individuals (i.e., individuals carrying one copy of the dominant allele and one copy of the recessive allele). In this case, both parents are heterozygous for a single gene trait (i.e., the ability to taste) which is ruled by complete dominance. In consequence, the expected phenotypic ratio in the progeny (F1) will be:
- Alleles: T (dominant taster allele); t (recessive non-taster allele)
- Parental cross: Tt x Tt
- Punnett Square from this cross:
T t
T TT Tt
t Tt tt
Expected F1 phenotypic ratio: 3/4 taster (i.e., 1/4 TT genotype + 1/2 genotype Tt = 3/4 or 75%); 1/4 non-taster (tt genotype = 1/4 or 25%). Moroever, the chance that the first child has the taster phenotype is 3/4 (75%).

) A florist obtained a prize winning flower that he wants to breed to be sold. The trait that makes his flower stand out is dominant for a particular trait. In order to successfully breed this flower, he needs to make sure that the dominant trait is pure dominant and not a hybrid. What should the florist do to determine whether or not the flower is pure or hybrid for this trait?
Answer:
The correct answer is - Test cross.
Explanation:
A test cross is a cross that is made between an organism with an unknown dominant genotype and an organism that purebred recessive genotype for the particular trait. It determines if the unknown genotype of the individual being tested is purebred allele dominant or heterozygous for the trait.
If all offspring in F1 generation has phenotypically dominant trait then the tested organism is pure breed dominant and if half of the offsprings have the phenotypically dominant trait and half show recessive trait then the organism to be tested is heterozygous or hybrid.
Thus the aforementioned response is correct.
