Draw and Label a Pair of Homologous Chromosomes

The closer two genes are to each other on the same chromosome the less likely they are to be separated by a crossover event resulting in a lower recombination frequencyTo calculate the distance between m and p you would add the. 3 4 1 2 B.

One set of 23 chromosomes is inherited from the mother and the other set is inherited from the father.

. Homologous chromosomes pair along their length during prophase I of meiosis. The two members of each pair are called homologous chromosomes because they have the same genes. While two homologues are paired genetic exchange may occur between them in a process called _____.
