The frequency of recombination between gene pairs on the same chromosome as a measure of the distance between genes was explained by :
1 Gregor J. Mendel
2 Alfred Sturtevant
3 Sutton Boveri
4 T.H. Morgan
Explanation:
Alfred Sturtevant used the recombination frequency between gene pairs as a measure of physical distance between genes and mapped their position on the chromosome. This process of mapping the gene position was termed as gene mapping. It can be used to determine the exact location of a gene on the chromosome.

A gene showing codominance has ;
1 Both alleles independently expressed in the heterozygote.
2 One allele dominant on the other
3 Alleles tightly linked on the same chromosome
4 Alleles that are recessive to each other
Explanation:
The phenomenon of expression of both the alleles in a heterozygote is called co-dominance. The alleles which do not show dominance -recessive relationship and are able to express themselves independently when present together are called codominance alleles.

Which of the following pairs is wrongly matched?
1 Starch synthesis in pea : Multiple alleles
2 \(\mathrm{ABO}\) blood grouping : Co-dominance
3 T.H. Morgan : Linkage
4 XO type sex : Grasshopper determination
Explanation:
Starch synthesis in pea is controlled by pleiotropic gene. A pleiotropic gene is a single gene which produce multiple unrelated phenotypes. Starch synthesis in pea seed is controlled by one gene. In BB (dominant homozygote's) large starch grains are produced while bb homozygote's have lesser efficiency in starch synthesis and produced smaller starch grain.

Genes on same chromosome can be
1 Linked
2 Homologous
3 Autosomes
4 Identical alleles
Explanation:
Genes on the same chromosome can be linked. Linked genes are located on the same chromosome tend to be inherited together, violating the principle of Independent Assortment proposed by Gregor Mendel.
