A single recessive gene on that X chromosome will be expressed in the phenotype because there are no corresponding genes on the Y chromosome.

Webb2 okt. 2024 · The ratio between the offspring population for an observable characteristic is the phenotype ratio. On the other hand, the ratio between the genetic makeup among the offspring population is the genotype ratio. This is the main difference between phenotype and genotype ratio.
