You are a xenogeneticist studying groggins from the planet zabar. they do not have males and females, but there are mating types: alpha and omega. groggins are hard to grow in the lab, so you are using several families of parents and offspring to determine the genetic basis of the tail spine color trait. spines may be black, red or yellow. use the data from the families below (parental gentoypes are unknown) to answer questions 1 - 3. parents offspring family alpha omega alpha omega 1 black red black black 2 yellow yellow yellow ½ yellow ½ red 3 black yellow black black 4 red yellow yellow red 5 black yellow ½ black ½ black ½ yellow ½ yellow 6 black red ½ black ½ black ½ yellow ½ yellow 7 red black black red 1. the genotype of the red parent in family 6 is best described as: a. r/r b. r/r c. r/y d)x /x e. x /

The asian shore crab (hemigrapsus sanguineus) is an invasive species that has impacted the atlantic coast. predict what characteristic of this invader would most likely disrupt the biodiversity of this area.

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.
