What are nucleotide segments of DNA molecules that make up genes and are expressed in the phenotype of an organism?

These are called Exons - ex for expressed. The 'gene spacers' that are removed from the messenger Rnas and are not expressed are called Introns.

What do you call the physical appearance of an organism?
phenotypeI believe it's phenotype.it is!
The phenotype of an organism does what?
The phenotype is the set of observable properties, characteristics, and traits of an organism.
An organism's phenotype is its?
an organism's phenotype is its fetures
What are an individuals expressed traits called?
genotype
What is recessive gene and dominant gene?
A dominant gene is always expressed if present, and the recessive gene is only expressed with the homozygous recessive genotype. For example, if the dominant gene is red (represented by the letter R) and the recessive gene is white (represented by the letter r), then a homozygous dominant organism's genotype will be RR, and its phenotype will be red. If the organism is homozygous recessive, then the genotype will be rr and the phenotype will be white. If the organism is heterozygous, then the genotype will be Rr, and the organism will be red.
What ultimately determines the phenotype of an individual?
Phenotype is what traits are expressed by the organism. So what ever is the dominant Genotype of the organism will determine the Phenotype. For example a dominant R gene will be the Phenotype in RR and Rr. However, if the organism has two recessive rr then the recessive gene will determine the Phenotype.

What is the difference between a karyotype and a phenotype?
The phenotype is what you will see when genes are expressed in an organism. Karyotype is all the genes in an organisms DNA.
What is a pehnotype?
A phenotype refers to the traits being expressed in the organism, for example my phenotype is blue eyes, brown hair and blood group A +ve.
What are inactive alleles?
Inactive alleles (usually called recessive) are not fully expressed in the phenotype of the organism.
What we call the observable expression of genes present in an organism?
When genes are expressed, the result is called phenotype. What is actually in all the genes (some are recessive) is called the genotype.
Is The appearance of an organism its phenotype or genotype?
the appearance of an organism is it's phenotype
What is the entire genetic make up of an organism called?
it relates to the phenotype A phenotype is how the organism looks based on which genes are expressed. A genotype is how the organism is genetically structured, including recessive genes that are not apparent when looking at the organism. Some diseases, like colorblindness, are recessive and are only expressed when there is not a dominant gene to override it. The entire genetic makeup of an animal is its genome.
What is the difference between an inactive allele and an expressed allele?
The inactive allele is invisible in an organism while an expressed allele is the dominant allele and therefor is the phenotype.
How are genotypes and phenotype related?
Genotype and phenotype are to words that are not related. Genotype refers to classification by comparing genetics. Phenotype refers to classification according to the appearance of an organism.
What is the traits produced by an organism's genes?
A genotype is the entire genetic make up of an organism. The phenotype is the actual expressed traits or characteristics found within an organism. The distinction between genotype and phenotype can be made based on dominant and recessive genes.
The physical expressions of a gene are known as an organism's?
The phenotype of the organisms. The physical and behavioral traits of the organism.
