Information Suppose that an individual is heterozygous for the following change in chromosome structure: Normal chromosome L M N . O P Q R S T U V X Inversion chromosome: I m n . o p q r w v u t s x Note that alleles present on the chromosome are indicated using letters; the centromere is indicated with a " Suppose that these two chromosomes replicate prior to meiosis (producing four total sister chromatids). The two replicated chromosomes then attempt to synapse during prophase I. Question 43 (4 points) d What is the allele and centro-mere composition of the four products of meiosis if there is a crossover between T and U?
Explanation / Answer
Two chromatids will be same as parental chromatids given in the question The other two are LMN*OPQRSutsx lmn*opqrwTUVWX
