Na certain plant, blue (b) flower color is dominant to white (b). you have a blue flowered plant and a white flowered plant. what do you know about the genotype and phenotype of each plant? now you cross the plants and all the offspring are blue. what have you learned about the genotypes of the original plants?

If blue flower colour is dominant to white then there will be two conditions for the dominant plant. It will either have homozygous dominant (BB) alleles or it will have heterozygous alleles (Bb). The phenotype will be blue flower colour.

As the white flower is recessive,it will have the alleles bb. The phenotype will be white flower colour.

If all the offsprings produced by the cross are blue, then it means that the dominant blue plant was homozygous for the trait. All the offsprings produced will have blue colour and a heterozygous genotype.

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a
