Want this question answered?
This is an odd question. ANYTHING that isn't a trait would NOT be a characteristic. So ... a table, or time.
Dwarfism is a dominant trait in humans.
The morphological evidence which is shown in fossils to modern animals supports evolution because some dinosaurs, for instance, had feathers and we can obviously see that trait today in birds. The biochemical evidence, which comes in the form of DNA comparison and amino acid similarities, shows that we related closely to monkeys and pigs, which suggests that we have close ancestors to these animals.
African Lion,White African Lion and snow Leopard are some of the homologous of the Bengal Tiger ,through comparative genetic analysis.
the 2 alleles of the gene for the trait are different on the 2 homologous chromosomesBeing heterozygous for a trait means that they have different alleles for a trait. For instance: Tt would be heterozygous and TT or tt would be homozygous because they are both eitehr little or big t's.it mean the gene is not pure or for example suppose a person is blood group A but actually he is having A and O; because O is recessive trait the gene express the A trait instead, making the person having blood group A.
Genotype codes for phenotype. Phenotype is the expressed trait, for example, black fur. The genome that codes for black fur would be BB for example
No some humans seem to do without that trait.
Some schools of psychology do consider sickly a personality trait.
The trait that is being masked is recessive, and the trait that is doing the masking is dominant.
homologous chromosomes

Well there is Carbon monoxide, And other types of gases that come out of organisms like for example, Cows, Humans, What goes into trees, All sorts of things. Enjoi :) - Cameron
