Is a gene a genotype?
In a broad sense, the term “genotype” refers to the genetic makeup of an organism; in other words, it describes an organism’s complete set of genes. In a more narrow sense, the term can be used to refer to the alleles, or variant forms of a gene, that are carried by an organism.
The genotype of an organism is defined as the sum of all its genes. The phenotype of an organism is the observable physical or biochemical characteristics of an organism, determined by both genetic make-up and environmental influences.
What is the difference between gene and genotype?
Genes are sections of DNA that determine certain traits or characteristics. … An organism’s genotype consists of its entire set of genes. Every human has a unique genotype, which explains the vast variety in human appearance and biology.
What are the 3 types of genotypes?
There are three types of genotypes: homozygous dominant, homozygous recessive, and hetrozygous.
What is the relationships between genotype & phenotype? Genotype refers to the alleles you possess for a particular gene or set of genes. Phenotype is the physical trait itself, which may be influenced by genotype and environmental factors.

What is as genotype?
For a child to be born with the condition, both parents must carry a sickle-cell gene, (known medically as AS genotype), which is passed from one generation to the next. If someone with a trait marries another person with it, there’s a higher chance that their child will be born with the disease.
What is in a gene?
Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.
