Some regions of chromosomes are more likely to cross over compared to others. such a region is called a "hot spot". gene a and gene b, which are in a hot spot for crossing over, are 5,000,000 bp apart on the same chromosome. gene c and gene d are also 5,000,000 bp apart but they are not in a hot spot. if you conducted two-factor crosses to compute the map distance between genes a and b and between genes c and d, would the map distances be the same between a and b compared to cand d? explain why or why not.

Explained

Explanation:

If neither of the pairs of genes was in a hot spot, the map distance would likely be the same. However, in this case it is said that although both pairs of genes are 5,000,000 bp apart, genes A and B are present in a hot spot. This means genes A and B are more likely to experience recombination and produce recombinant offspring in the F2 generation due to crossing over. As a result, the map distances for A and B will be larger than the map distances for C and D because a map unit is the number of recombinant individuals divided by the total number of individuals, which is then multiplied by 100. Since a greater percentage of individuals would be recombinant in the F2 generation, A and B will have a larger map distance.

explanation:

common management practices in dairy and poultry farming are: (i) proper shelter facilities and their regular cleaning. (ii) some basic hygienic conditions such as clean water, nutritious food, etc. (iii) animals are kept in spacious, airy, and ventilated place.
