1. Strong Avengers (Earth's Mightiest Heroes) who normally have tall stature (+), long hair (+), and love hammers (+). But three recessive mutations showed up (likely due to gamma radiation) that result in short statured (ss) Avengers that have short hair (sh) and are allergic to hammers (ah). Data from a three-point testcross are shown below: Phenotype Genotype # Scored Normal + + + 351 Short statured Ss + + 81 Short hair 39 Allergic to hammers + + ah 4 Short statured, rounded ears 1 Short statured, allergic to hammers ss + ah 45 Short hair, allergic to hammers + sh ah 78 Short statured, short hair, allergic to hammers ss sh ah 401 ТОTAL 1000 (a) List the genotypes that are blank in the Table. (b) List the parental and double-recombinant genotypes, make sure you clearly identify which is which. (c) Calculate the map distance between the following two adjacent genes: short statured (ss) and allergic to hammers (ah).
