In radishes, the gene that controls color exhibits incomplete dominance. pure-breeding red radishes (rr) crossed with pure-breeding white radishes (ww) make purple radishes. what are the genotypic and phenotypic ratios when you cross a purple radish with a white radish?

Genotype ratio= 1 RW: 1 WW

Phenotype ratio= 1 purple: 1 white

Explanation:

According to the given information, the gene for the color of radishes exhibits incomplete dominance and the heterozygous genotype gives purple color to the radishes. The genotype of the heterozygous parent plant with purple radishes would be "RW". A cross between a purple radish (RW) and a white radish (WW) would give progeny in following ratio=

Genotype ratio= 1 RW: 1 WW

Phenotype ratio= 1 purple: 1 white

answer: the correct option is d. enzyme

lactase and carbonic anhydrase are the examples of enzymes.

lactase is an enzyme, which is present in the small intestine of mammals. it in the digestion of the disaccharide, lactose ( milk sugar) by converting it into two monosachharide, which are glucose and galactose.

carbonic anhydrase is present in the red blood cells. this enzyme plays significant role in the transport of co₂. it in the conversion of co₂ and h₂o into carbonic acid, which is then dissociated into bicarbonate ions and hydrogen ions.
