Snapdragons, a flowering plant popular with gardeners, can have red, white, and pink colored petals. when snapdragons with red petals (rr) are crossed with snapdragons having white (rr) petals, the offspring have pink petals. the pink coloration (rr) is a phenotype in between the red and white parental phenotypes. what is this kind of inheritance pattern called?
a)
classic dominance
b)
bipolar inheritance
c)
incomplete dominance
eliminate
d)
recessive inheritance

One statements is an example of a scientific observation. another statement is an example of a scientific explanation. identify the correct statement for each category to illustrate how scientific explanations are inferred from scientific observations.

Considering the yellow and green pea color phenotypes studied by gregor mendel: a. what is the biochemical function of the protein that is specified by the gene responsible for the pea color phenotype? (1 point) b. a null allele of a gene is an allele that does not specify (or encode) any of the biochemical function that the gene normally provides (in other words, either no protein at all or only non-functional protein is produced from it). of the two alleles, y and y, which is more likely to be a null allele? (1 point) c. in terms of the underlying biochemistry, why is the y allele dominant to the y allele? (2 points) d. why are peas that are yy homozygotes green? (1 point) e. the amount of protein produced from a gene is roughly proportional to the number of functional copies of the gene carried by a cell or individual. what do the phenotypes of yy homozygotes, yy heterozygotes, and yy homozygotes tell us about the amount of sgr enzyme needed to produce a yellow color? explain your reasoning.
