What is genotype refers to having identical alleles?
Copies of genes are referred to as « alleles, » and because of the way reproduction works, the alleles can carry identical copies of a gene or different copies, depending on what is passed on by each parent. Identical alleles means that a person’s genotype for that trait is homozygous .
Are combinations of alleles known as a genotype?
Alleles are often represented by upper and lower case letters. The upper case letters represent the dominant form while the lower case letters represent the recessive form. The combination of alleles for any genetic make-up is known as an organism’s genotype. The expression of a genotype is called the phenotype.
What is gene vs allele?
An interesting difference between alleles and genes is that alleles produce opposite phenotypes that are contrasting by nature. When the two partners of a gene are homogeneous in nature, they are called homozygous. Genes are something we inherit from our parents- alleles determine how they are expressed in an individual.
