A mapping experiment in strawberries shows that the genes for color and plant height are separated by 16cM. In a cross between a heterozygous plant (CcHh) and a homozygous recessive plant, what percent of offspring would inherit a chromosome carrying cH from the heterozygous parent.... 1. if the heterozygous parent’s alleles are in repulsion? _________________ 2. if the heterozygous parent’s alleles are in coupling?

At the point when the alleles of one gene pair on one homologous chromosome pair arranges without affecting how the alleles of other gene pair on an alternate homologous chromosome pair groups during meiosis, the two gene pairs are said to autonomously assort. Be that as it may, autonomous arrangement possibly applies when the two gene pairs are situated on various chromosomes. At the point when two genes are connected on a similar chromosome, they can't freely group, and the mix of alleles found on a chromosome must be changed by recombination (getting over) during prophase I of meiosis.
Since recombination is progressively reasonable the farther separated two genes are situated on a chromosome, recombination frequency, which is the quantity of recombinant offspring partitioned by the complete number of them, is utilized to plan the general distances between genes on a chromosome. A recombination frequency of 1% is characterized as 1 map unit (m.u.), which is otherwise called centimorgan (cM).
