Questi letioni Status: Part : Monohyb To make some extra money this summer you decided to help out at a local organic berry farm One day while out picking strawberries you noticed that some of the strawberry plants were producing red berries, whereas others were producing purple berries Plant produces red strawberries Plant produces purple strawberries You asked the farmer who owns the berry patch about this observation He said that a plant that produced red strawberries was self-crossed and the resulting seeds collected and planted. Then in the next generation of plants, 678 plants produced red strawberries, and 211 plants produced purple strawberries 4. Write the genotypes of the parental plant and its progeny, using F and f to designate the different berry-colour alleles Please note: if more than one genotype is possible, please separate the genotypes with a comma and a space, e.g. FF, Ff, ff) (a) Genotype of the parent plant with red strawberries (1 mark) (b) Genotype(s) of the progeny plants that produced purple strawberries (1 mark) (c) Genotype(s) of the progeny plants that produced red strawberries (1 mark) QUESTION 5 5 pointsSave Answer Part l: Monohybrid Question 5 nformation 5.
