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%).
Which statement describes the role of a mitochondrion in providing a body with energy?

It combines blood and oxygen so that energy can be released from glucose.
It is the site where oxygen combines with small molecules and releases large amounts of energy.
It is the site where food is broken down into small molecules and amounts of energy
Answer:
It stores glucose that is taken from food so that respiration can happen later.

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

) 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.
