An individual that is heterozygous for an inversion has the following chromosomes (∗ is the centromere): M N O P Q • R S T U m n o t s r • q p u Assume that a crossover occurred between P and Q. Starting with “M” allele, list the remaining genes in order (NO spaces between the letters) of the chromosome resulting from crossing over. You must use upper and lower-case letters correctly and the * symbol for the centromere(s)
An individual that is heterozygous for an inversion has the following chromosomes
(∗ is the centromere):
M N O P Q • R S T U
m n o t s r • q p u
Assume that a crossover occurred between P and Q. Starting with “M” allele, list the remaining genes in order (NO spaces between the letters) of the chromosome resulting from crossing over. You must use upper and lower-case letters correctly and the * symbol for the centromere(s).
Introduction :- Crossing over is defined as the exchange of segments ( chromosomal segments) between two homologous chromosomes during the process of meiosis , for example - During the formation of male and female gametes , paired chromosomes from each parent are aligned and exchange of genetics segments takes by the formation of synaptonemal complex ( bivalent formation ) . Centromere is the region of primary constriction in chromosomes which separates the chromosome into a short arm (p) and a long arm (q) . The function of the centromere is , joining of two sister chromatids .
