PART A. MONOHYBRID PROBLEMS CONCERNING TOMATO Given: . Tall stature is dominant over dwarf stature (D, d). Smooth-skinned fruit is dominant over peach (hairy) fruit (Pp). Oblong fruit shape is dominant over normal fruit shape (O, o) Simple inforescence is dominant over compound inflorescence (S, s). . Purple stem is dominant over green stem (A, a). Fasciated (consisting of many chambers) fruit is dominant over nonfasciated fruit (E,f). Red-fleshed fruit is dominant over yellow-fleshed fruit (R, r) Opaque skin, as in bright fruit, is dominant over transparent skin, as in dull fruit (Y, y). Note: The genes for stature, skin type, fruit shape, and inflorescence belong to one linkage group (that is, they are all inherited together); genes for stem color and fasciation belong to another linkage group. Genes R and Y are independent of these linkage groups and of each other. 6. Why are certain genes usually inherited together? us tall tomato plant (genotypeis pollinated by a homozygous dwarf plant (genotype

Explanation / Answer

6- certain gene are carried along together because they are linked to eachother or present close to eachother on the chromosome.

a- tall plant DD

Short plant dd

7- d for pollen nuclei

D for egg nuclei

8-Dd is f1 genotype

9- it will be tall genotype

10-d and D for pollen

D and d for egg

Genotype ration 1:2:1

Phenotype ration 3:1
