What is true of the allele pair of someone with a genotype of tt?
The allele pair of someone with a genotype TT is homozygous dominant.
Ear lobes can be either attached or detached the allele for attached earlobes is recessive and the allele for detached earlobes is dominant what must be true if a boy is born with attached your lobes?
He has at least one E allele is correct. I take the quiz
True or False In heterozygous individuals only the recessive allele is expressed?
In heterozygous individuals, only the dominant allele is expressed. The recessive allele is present, but not expressed
What genotype is not true-breeding?
An individual with a heterozygous genotype cannot be true-bred.
Which is not true of an organism's genotype?
If an organism is a true-breed, the organism's genotype would be homozygous. "Homo" is the same and the alleles in a true-breed are identical.

The allele pair of someone with a genotype TT is homozygous dominant.
Earlobes can be either attached or detached. The allele for attached earlobes is recessive and the allele for detached earlobes is dominant. What must be true is a boy is born with attached earlobes?
He has a homozygous genotype

What is true of someone with a genotype TT?
it is homozygous dominant
When two alleles of an inherited pair are different the dominant allele determines the organisms appearance?
True

True or False In heterozygous individuals only the recessive allele is expressed?
In heterozygous individuals, only the dominant allele is expressed. The recessive allele is present, but not expressed
Is it true that people who are heterozygous recessive allele but who have a normal phenotype eill not pass the harmful recessive allele to their kids?
It depends on the genotype of the childs other parent. If your partner is heterozygous as well then there is a 25% chance your child will be homozygous recessive. If they are homozygous dominant then none of your children will have the phenotype of the recessive trait. They will just possibly be carriers of the recessive allele.

Why does natural selection act on phenotype rather than genotype of an organism?
This seems to be an odd question to ask... Unless I'm mistaken, the phenotype of a given organism is governed by its genotype, and changed a fair amount by the organism's environment. Consider the following circumstances: Organism A has a long set of arms, and has a "long arm" allele. Organism B has short arms and a "short arm" allele. For example, A's genotype has the "long arm" allele, and seen in its phenotype it has long arms. The converse is true for B. Judging by your usage of technical terms in your question, I'm sure I don't need to tell you that A will out-compete B, assuming they are in a food-is-up-high environment. So, A will end up with more offspring than B, again assuming that A and B are members of different species. Eventually organism A will become prevalent, and natural selection will have caused there to be more organisms with the "long arms" phenotype, and the "long arm" allele in their genotype. In summation, Genotype governs Phenotype, and the best geno- and phenotypes will be chosen by natural selection. By an organism having a superior phenotype, it also has a superior genotype.
