If Mendel had an idea of linkage, then which of the following laws, he would not have been able to explain?
1 Law of indominance
2 Law of independent assortment
3 Law of segregation
4 Law of purity of gametes
Explanation:
Mendel was not able to get any linkage due to the Law of independent assortment.

Select the correct statement from the ones given below with respect to dihybrid cross
1 Genes far apart on the same chromosome show very few recombination’s
2 genes loosely linked on the same chromosome show similar recombination’s as the tightly linked ones
3 Tightly linked genes on the same chromosomes show very few recombination’s
4 Tightly linked genes on the same chromosomes show higher recombination’s
Explanation:
Recombination is a rearrangement of genes during the process of meiosis, if genes are tightly linked on the same chromosome, they show very few recombination.

Select the incorrect statement from the following.
1 Baldness is a sex limited trait.
2 Small population size results in random genetic drift in a population
3 Linkage is an exception to the principle of independent assortment in heredity.
4 Galactosemia is an inborn error of metabolism.
Explanation:
Sex-influenced traits are autosomal traits that are affected by sex. If a male has one recessive allele, he will reflect that trait, but for the female to reflect that same trait it will require two recessive alleles. But these are dominant in males and recessive in females. One such gene is pattern baldness. Those men who inherit the gene from either parent lose hair (get bald) as they age, though women have them only if they inherit it from both parents and are therefore, homozygotes.
