Name P1. (10 pts) Refer to the cell shown at right. (Note:Figure is not shown. The cell has two pairs of chromosomes) Note for Sample Exam: Draw a diploid cell in Interphase with two pairs of chromosomes that alleles A and B. On the homologous chromosome show alleles a and b. On the other pair of chromosomes show alleles D and d can be distinguished by the positions of their centromeres. On one chromosome show a) Show the appearance of this cell at Metaphase I of meiosis. Label an example of sister chromatids and homologous chromosomes. Show all gene copies that would occur on all DNA strands. b) Show the cells which would result from the first division of meiosis and the second division of meiosis. Show all gene copies on all DNA strands. c) The haploid number of chromosomes in this on d) List all the gametes that Sutton would have predicted that this P2. (8 pts) A new species of butterfly is discovered in the Brazilian rain forest. Two different wing color phenotypes are observed, orange and white. Pure breeding lines of each phenotype are established, and reciprocal crosses are done between them. The following results are observed: P orange females X white males P white females X orange males F1 all white females : all orange males FI all orange females and males Obviously this trait is affected by a sex linked gene. What result would you have observed if the trait was controlled by an autosomal gene? a) b) Which is the heterogametic sex in this species? c) Show a genetic model to explain these results. Be sure to show all possible genotypes of males and females and the phenotype each would produce. Use W and w as the symbo your genes. ls for d) Fill in the genotype of each parent and their F1 offspring in the crosses shown above on the lines provided
