Monohybrid Inheritance

Monohybrid inheritance

Inheritances of one characteristic and contrasting traits controlled by a gene.

Gene

The basic unit of inheritance consists of a DNA segment located on a specific locus of a chromosome

Allele

The alternative form of a gene for a specific trait that is located on the same locus of a pair of homologous chromosome

Phenotype

The observable characteristic of an organism.

Genotype

Genetic composition of an organism that cannot be seen

Characteristic

A heritable feature such as height, eye colour, blood group & dimples

Dominant allele

An allele that always shows its traits when it is present and suppresses the effect of the recessive allele

Recessive allele

An allele that shows its trait when both alleles are recessive alleles.

Homozygote

Both alleles at loci of a pair of homologous chromosomes are the same.

Heterozygote

Alleles at loci of a pair of a homologous chromosomes are different
