Answer:
Gene
Alleles
Genotype
Phenotype
Dominant allele
Recessive allele
H o m o zygous
Explanation:
A small section of DNA on a chromosome, that codes for a particular sequence of amino acids, to make a specific protein is known as a gene
Different versions of the same gene are called alleles. For example, the gene for eye color has an allele for blue eye color and an allele for brown eye color
The collection of alleles that determine the physical, or phenotypic characteristics of an organism is called the genotype
The physical characteristics of an organism controlled by the interaction of an organism's genotype with the environment is phenotype.
A term given to alleles that are always expressed when present is the dominant allele
A term given to alleles that are only expressed when two recessive alleles are present is the recessive allele
H o m o zygous- this is when an organism has two of the same alleles for a particular gene
