Step by step
Solved in 2 steps
- How is it that asymmetric cell division influences gene regulation? What are the factors that determine phenotype? and how the phenotypic expression goes beyond simple Mendelian models.How would you explain gene expression? How is it that a particular genotype is actually expressed as a phenotype? I am looking for details here, including an explanation of the molecular mechanisms involved.In some genes, like blood type, two alleles are expressed at the same time. What do we call this?
- A company that offers PGD terms an embryo “normal and healthy” if it has 46 chromosomes. Why is this statement misleading? , Two famous male actors had twins using a surrogate mother who carried two embryos that hadbeen fertilized in vitro, one with one man’s sperm and the other with the other man’s sperm. In terms of genetics, how closely are the babies, a boy and a girl, related to each other if they have different fathers?Why does a loss or an excess in genetic material lead to the expression of an abnormal phenotype?What is a gene and what do genes code for? What are alleles? Be specific.
