Genes that are passed on to you determine many of your traits, such as
your hair color and skin color
. Maybe Emma's mother has one gene for brown hair and one for red hair, and she passed the red hair gene on to Emma. If her father has two genes for red hair, that could explain her red hair.
What are the 3 types of genes?
Type I genes tend to be involved in immune response or sensory receptors while type III genes are involved in cell to cell signalling and type II genes are a complex mix of all three types.
What is gene explain with example?
Genes are
made up of DNA
. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. … For example, a gene on chromosome 7 that has been associated with cystic fibrosis is called the cystic fibrosis transmembrane conductance regulator; its symbol is CFTR.

What are the 4 types of genes?
The chemicals come in four types
A, C, T and G
. A gene is a section of DNA made up of a sequence of As, Cs, Ts and Gs. Your genes are so tiny you have around 20,000 of them inside every cell in your body! Human genes vary in size from a few hundred bases to over a million bases.
How many type of genes are there?

What are 2 kinds of genes?
An
allele
is one of two or more versions of a gene. An individual inherits two alleles for each gene, one from each parent. If the two alleles are the same, the individual is homozygous for that gene. If the alleles are different, the individual is heterozygous.
How can I improve my genes?
- Look at every day as a feedback loop. Strive for greater positive input that negative input.
- Don't limit ‘positive input' to just eating kale. …
- Shake things up a bit. …

How many genes are in a chromosome?
Chromosome 1 likely contains
2,000 to 2,100 genes
that provide instructions for making proteins.
What is the difference between DNA and genes?
DNA is the molecule that is the hereditary material in all living cells. Genes are made of DNA, and so is the
genome
itself. A gene consists of enough DNA to code for one protein, and a genome is simply the sum total of an organism's DNA.
What is a gene simple definition?
(jeen)
The basic unit of heredity that occupies a specific location on a chromosome
. Each consists of nucleotides arranged in a linear manner. Most genes code for a specific protein or segment of protein leading to a particular characteristic or function.
Where is gene located?
Genes are
contained in chromosomes
, which are in the cell nucleus. A chromosome contains hundreds to thousands of genes. Every normal human cell contains 23 pairs of chromosomes, for a total of 46 chromosomes. A trait is any gene-determined characteristic and is often determined by more than one gene.

- MTHFR;
- ESR1; and,
- AKT1.
