BIOL 3305 Lecture Notes - Lecture 26: Genomic Imprinting, Y Chromosome, Somatic Cell
Document Summary
8 genomic imprinting is generally due to the add-on of methyl groups to c nucleotides and chemical substance histone changes to silence a given gene. If this depends on the sexual activity of the parent who transmits the gene methylation must be reversible in ovarian and testicular cells. Dna polymerase iii what is a testcross breeding an organism of an unknown region genotype with a dominant phenotype with another. A woman found to have 47 chromosome , including 3 x chromosomes. Which of the following describes her expected phenotype male and females inherit a different number of x chromosome which leads to a pattern of inheritance different from that produced by genes located on somatic chromosome. Sry is best described as inactivate one random x chromosome. Given the parent s aabbcc x aabbcc, assume simple say-so for each trait and independent assortment.
