Pure breeding lines of Pea were taken regarding seed shape -round and wrinkled and were crossed with no intermediate between parents.All offfsprings were found to be round. These results show:
Co-dominance
Dominant-recessive relationship of alleles
Incomplete dominance
Overdominance relationship
The condition in which heterozygote has a phenotype intermediate between contrasting homozygous parents is called:
Dominance
Co-dominance
Over-dominance
Incomplete dominance
Locus stands for:
Position of gene on homologous chromosomes
Regions of chromosomes
Position of allele within a DNA molecule
Close regions of same chromosomes
Self-fertilization of F1 dihybrids, following independent assortment of alleles will result in:
3/16 tall,round : 3/16 dwarf wrinkled
9/16 tall,wrinkled : 1/16 dwarf,round
9/16 tall round : 1/16 dwarf round
3/16 tall,wrinkled : 3/16 dwarf round
