False. An organisms physical appearance is its phenotype.

What describes organisms or genotypes that are homozygous for a specific trait that always produce offspring of the same phenotype?
Organisms or genotypes that are homozygous for a specific trait and always produce offspring of the same phenotype are said to be true breeding. This means that when bred with another organism of the same genotype for that trait, all offspring will display the same characteristic.
The Phenotype determines genotype?
Phenotype does not determine genotype. Actually a genotype includes an organisms entire hereditary information. A phenotype is simply the organisms actual observed properties including appearance, development and behavior.
What genotype is not true-breeding?
A heterozygous genotype (e.g. Aa) is not true-breeding because it carries two different alleles for a trait and can produce offspring with different genotypes when crossed. True-breeding genotypes are homozygous for a particular trait (e.g. AA or aa) and will consistently produce offspring with the same genotype when crossed.
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.
Which is not true of an organism's genotype?
An organism's genotype does not change over its lifetime, as it is determined by its inherited genetic material. The genotype represents the full genetic makeup of an organism, including all its genes and alleles. It is the genetic information that influences the organism's traits and characteristics.
When two alleles of an inherited pair are different the dominant allele determines the organisms appearance?
Not necessarily. The dominant allele is the one that is expressed in the phenotype when present in the genotype, but both alleles can contribute to the organism's overall appearance in more complex ways through incomplete dominance or co-dominance.

Can 2 organisms have different genotypes but the same phenotype?
No. It is possible for the reverse to be true, two organisms can have the same phenotype but a different genotype. This is because the phenotype is what you will see on the outside whereas the genotype is the combination of alleles and since this determines the phenotype, two organisms with the same genotype will have the same phenotype. So, basically, no. Actually 2 organisms can certainly have different phenotypes with the same genotype--this refers to the concept of penetrance. Some people can have the gene for a condition but never show symptoms. An excellent example of this is the disease neurofibromatosis. This disease has very variable penetrance in which a child of an affected parent may show no signs of the disease, but then have a child with a severe form.
True or false The actual gene makeup of an organism is its phenotype?
False. The actual gene makeup of an organism is its genotype, while its phenotype refers to its observable physical and biochemical characteristics.
What genotype is not true-breeding?
A heterozygous genotype (e.g. Aa) is not true-breeding because it carries two different alleles for a trait and can produce offspring with different genotypes when crossed. True-breeding genotypes are homozygous for a particular trait (e.g. AA or aa) and will consistently produce offspring with the same genotype when crossed.
What is true of someone with a genotype TT?
it is homozygous dominant
What is true of a woman with the genotype?
She is a carrier of hemophilia but does not have the condition
What is true of someone with genotype TT?
it is homozygous dominant
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.
