Chromosome •Genes, the unit of inheritance are located on the chromosomes of the gametes. •Passed from parents to progeny. •Chromosome term was introduced by Waldeyer in 1888. •Number of chromosomes is fixed in each cell but varies from species to species. •In human beings, the total number is 46 or 23 pairs named as ‘diploid’ (2n).
allele is dominant over the green seed allele. The genes for seed texture and those for seed color are on different chromosomes. A plant heterozygous for seed texture and seed color is crossed with a plant that is wrinkled and heterozygous for seed color. *R = round, r = wrinkled, Y= yellow, y = green a. Construct a Punnett square for this ...
