In diploid rice, plants homozygous for the recessive allele so“! are relatively short in stature. Plants homozygous for a dominant allele. Xa4, conesponding to a second genelocated on a different chromosome. are res‘stant to bacterial blight. The wild—type SD‘l allele is dominant to the recessive, and results in plants of tall stature. The wild—typexad allele is recessive to the dominant mutant alleleI and the wild-type results in a lack of resistance to bacterial blight. A fan'ner crosses two hue—breeding plants, it can be assumed they are homozygous at all loci. One plant is hcrnozygous for ed! {and wild—type at all other loci) and the otherplant is Mrrmzygws for Xa4 {and wild-type at all other loci), which of the following statements is correct? SEER-3d ANSWBI'! b. The F1 progeny will be dihybrids. ANSWBIS! a. The F1 progeny will be monohybrids.b. The F1 progeny will be dihybrids.c. Three—quarters ofthe F1 progeny will be resistant to bacterial blight. while one-quarter will be short.(1. a and c e_bandc
