The genotype of the parents with the given phenotypes below are as follows:

  • SsFF × ssff
  • SsFf × ssFf
  • SsFf × Ssff
  • Ssff × ssFf

What are genotype and phenotypes?

Genotype refers to sum total of genes whivhnan organism have for a particular trait or character.

Phenotype refers to the physical expression of the genotype of an organism.

Assuming S is dominant over s for long ears and short ears respectively.

Also, F is dominant over f for Fur and gutless respectively.

The genotype of the parents with the phenotypes below are as follows:

  • long ear, fur x short ear, furless = SsFF × ssff
  • long ear, fur x short ear, fur = SsFf × ssFf
  • long ear, fur x long ear, furless = SsFf × Ssff
  • long ear, furless x short ear, fur = Ssff × ssFf
