List down all affectedIn a certain plant, the orange flower allele (Y) is dominant to the yellow flower allele (y). An allele that prevents flower color pigment formation (W) results in white flowers irrespectively of the Y and y alleles, and is dominant to an allele (w) that allows flower color formation.

- If an allotetraploid species is made up of two ancestral genomes, A and B, with each of them having a basic chromosome number of seven. The resistance to the pathogen attacking the foliage of plants is controlled by a dominant allele located at the F locus. The recessive alleles F^a and F^b show sensitivity to the pathogen. Plants with at least on F^A allele are resistant to the pathotype 1 and 2 (regardless of the genotype in B genome), and plants with at least one F^B allele are resistant to pathotypes 1 and 3 (regardless of genotype in A genome). What proprtion of the self-progeny of F^AF^a F^BF^b plant will be resistant to pathotype 1, 2 and 3?In a particular plant, two genes control leaf shape and color. Round leaves (R) are dominant to jagged leaves (r). Yellow fruits (Y) are dominant to white fruits (y). If you crossed a homozygous round, heterozygous yellow plant with a heterozygous round, white plant, what are the genotypes of the plants involved in this cross? Group of answer choices RrYY x RRyy RRYY x rryy RrYy x RrYy RRYy x RryyIn radishes, flower color may be red, purple, or white. The edible portion of the radish may be long or oval. When only flower color is studied, no dominance is evident, and red x white crosses yield all purple. Determine the appropriate allele symbols and indicate which genotypes lead to which phenotypes. If the F1 purple plants described above are interbred, what will be the genotype and phenotype ratios in the F2 generation? Regarding radish shape, long is dominant to oval in the typical Mendelian fashion. What will be the phenotype ratios in the F2 generation of a cross between a true-breeding red, long radish and a white, oval radish?
