Question

What genes are recessive?

Answer 1

Genes are defined as the functional unit of heredity and are made up of DNA which acts as the instructor for making up the proteins. It contributes to function as a segment of deoxyribonucleic acid.

Complete answer:
Recessive is a quality of a gene that is found in a relationship of two versions of a gene under which the alleles are different and the dominant allele will be expressed with the effect of the other allele to be masked which is the recessive gene. Every organism is composed of two alleles which are packed into chromosomes under the DNA and for each gene, there is one inherited parent which will be the mother and the other from the father. a recessive gene gets expressed only when the organism consists of two recessive alleles for that gene which is known as the homozygous recessive gene. These types of genes are not manifested in an individual unless the individual's copies of that gene have a particular genotype. They help in the functioning of the proteins consisting of three mutations that segregate the disease under a recessive model that include large deletions.
Some of the traits shown by the organisms are carried out by the single gene which is either dominant or recessive that includes the dimples, cleft chin, freckles and a widow's peak which are the dominant traits and the person who does not have these traits is recessive. recessive genes include other traits which are expressed as the attached earlobes or the inability to roll one's tongue and round eyes.

Note:
Some of the lethal mutations are recessive due to which people equate the recessive gene to be the bad one. Some of the lethal alleles which cause the organism to die are recessive and the recessive lethal allele does not get ts in the heterozygous form.
