In radishes, flower color can be red, purple or white. The allele for long (O) tuber shape is completely dominant over oval (o). With regard to flower a cross between red and white resulted in purple F1 progeny. When the F1 plants were self-pollinated a phenotypic ration of 1 red: 2purple: 1 white was observed. Determine the F1 and F2 phenotypes from a cross between pure-breeding red long radish and one that pure breeding white oval shaped.

Diego conducted an experiment to find out what kind of ball bounces the highest when dropped from a five-foot platform. he used a golf ball, a tennis ball, and a soccer ball. he dropped each ball from the balcony once. diego recorded his observations after each drop. what can diego do to best improve the reliability of his results? a) drop each ball from the platform three more times b) record his observations in more than one unit c) write at least two scientific questions after the experiment is complete d) share his results with other people who have done similar experiments you for the !
