What genotype is not true-breeding?
An individual with a heterozygous genotype cannot be true-bred.
What describes organisms or genotypes that are homozygous for a specific trait that always produce offspring of the same phenotype?
Yes, homozygous with homozygous (both the same genotype) will produce homozygous of the same genotype
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 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 is true about early efforts about naming organisms?
Names often described detailed physical characteristics of a species.

When two alleles of an inherited pair are different the dominant allele determines the organisms appearance?
True

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.
Is it true a physical change never alters the form or appearance of a substance?
No. For example, ice to water.

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.
Does the genotype regulate the enzymes present in an organism?
It is true that the genotype regulate the enzymes present in an organism. Every characteristic about an organism is influenced by its genotype.
What is true about early efforts about naming organisms?
Names often described detailed physical characteristics of a species.
What is true for a physical change as well as a chemical change?
A chemical has changed appearance in both a physical and chemical change. It cannot stay the same or it wouldn't have changed.
What is true of a woman with the genotype?
She is a carrier of hemophilia but does not have the condition
Does recombination always alter a cell's genotype?
True
