Question

Bed 29. Topic: Chromosome Mutations The apple pictured to the right was discovered in an orchard in England. Other apples on the same tree are red. You have a hypothesis that this apple is caused by chromosome nondisjunction very early in the formation of the fruit. Apples are usually diploid, and apple color is determined by a single locus with two alleles: the red allele R and the green allele r. R is dominant to r. a. Draw the relevant chromosomes of a non-dividing cell from a normal red apple on the same tree. [2 pts] b. Draw the relevant chromosomes for a non-dividing cell from each half of the striped apple. (a cell from the green half and a cell from the red half). [3 pts) C. A fruit superintendent at the orchard, commented to the local newspaper that if the seeds from this apple were planted, the mutation might be inherited in the next generation to give more striped apples. Do you think the superintendent is correct? Why or why not? Explain briefly in the space below. [3 pts]

Answer 1

Hello MARKS Answeho a) Rr (red) PRISC SysRg b) or (green). Rr (red) c) Chromosomal non-disjunction occurs very randomly and is not inherited. so, there is no chance of seeing stripped apples in the next generation. n. chromosomal disorders occurs during the formation of the reproductive cells and they occur accidentally. This essor will remain for the individual where the reproductive cell formed abnormal. This abnormallity ality need not be carried to the next generation and they can't be passed on. please rate my Answes 12
