Document Summary

And they were dichotomous - they only gave one or the other traits. Either brown or white. nothing else. same for the appearance - smooth or rough. And colour of the ower - white or purple. Traits are genes in this situation. codes for the colour of seed. Alleles - one codes for brown while the other codes for white. He cross fertilized the brown seed line with white rst line. We can conclude the brown allele is dominant. In the second generation he got 3/4 brown and 1/4 white. the peas inherited one brown allele from their parent and one white. all have bw. The second generation has bb, bw, bw, ww. Histones are responsible for the assembly of the dna into chromosomes. Humans have 23 but other mammals have different numbers. Each strand is connected by a phosphate and a deoxyribose. sugar phosphate backbone. Nucleotide bases: adenine - thymine and guanine - cytosine.
