A monohybrid cross is a cross between two homozygous individuals, which produces the opposite phenotype for a particular genetic characteristic. A monohybrid cross is made up of two monohybrid characteristics ( straight hairline and widow's peak). The monohybrid cross is in charge of passing one gene on. Geneticists utilise monohybrid crosses to study the expression of heterozygous genes passed down from parents to homozygous offspring.

= Ww ( straight line) x ww (widow's peak)

= Ww ( straight line) : Ww ( straight line) : ww (widow's peak) : ww  (widow's peak)

Hence, equal chances exist for straight line and widow's peak.
