Principle of Inheritance and Variation

When a cluster of genes show linkage behavior they
1 do not show a chromosome map
2 show recombination during meiosis
3 do not show independent assortment
4 induce cell division
Explanation:
When a cluster of genes show linkage behavior, they do not show independent assortments. Linkage may be defined as the tendency of two or more genes of the same chromosome to remain together during the process of inheritance. In linkage, during meiosis, chromosomes move as a unit and all the genes of a chromosome go together and do not assort independently as expected according to Mendel law of independent assortment, only the genes situated on different chromosomes pair assort independently.

Percentage of recombination between \(A\) and \(B\) is \(9 \%, \mathrm{~A}\) and \(\mathrm{C}\) is \(17 \%, \mathrm{~B}\) and \(\mathrm{C}\) is \(26 \%\), then the arrangement of genes is
1 \(\mathrm{ACB}\)
2 BAC
3 BCA
4 \(\mathrm{ABC}\)
Explanation:
One map unit or centimorgan (cM) is a unit to measure the distance between genes on the chromosomes. It is denoted by map unit. The recombination frequency between three genes are: \(\mathrm{A}-\mathrm{B}=9 \%\) \(\mathrm{A}-\mathrm{C}=17 \%\) and \(\mathrm{B}-\mathrm{C}=26 \%\) By manipulating, the three possibilities of their arrangements \(\mathrm{A}-\mathrm{B}-\mathrm{C}, \mathrm{A}-\mathrm{C}-\mathrm{B}\) and \(\mathrm{B}-\mathrm{A}-\mathrm{C}\), it was found that the three genes must be arranged in order \(\mathrm{B}-\mathrm{A}-\mathrm{C}\) with the distance between B-A being \(9 \mathrm{cM}\) and \(\mathrm{A}-\mathrm{C}\) being \(17 \mathrm{cM}\) and the distance between \(\mathrm{B}-\mathrm{C}\) being \(26 \mathrm{cM}\).

When a tall plant with rounded seeds (TTRR) is crossed with a dwarf plant with wrinkled seeds (ttrr), the \(F_{1}\) generation consists of tall plants with rounded seeds. How many types of gametes an \(F_{1}\) plant would produce?
1 One
2 Three
3 Four
4 Eight
Explanation:
Since 4 types of gametes on \(\mathrm{F}_{1}\) plant would produce.

Depending upon the distance between any two genes which is inversely proportional to the strength of linkage, cross overs will vary from
1 \(50-100 \%\)
2 \(0-50 \%\)
3 \(75-100 \%\)
4 \(100-150 \%\)
Explanation:
Crossover is a process that occurs during meiosis, when homologous chromosomes exchange genetic material. The frequency of crossover between two genes is inversely proportional to the distance between them. It means when two genes are close together then the chance of recombination is very less. The percentage of crossover between two genes can vary from \(0 \%\) to \(50 \%\). It two genes are located on the same chromosome, but they are far apart, then the crossover frequency between them will be close to \(50 \%\). This is because there is a lot of space between the genes, so it is more likely that a crossover will occur between them.
