- “ No two people are exactly alike. Even monozygotic twins differ from each other.” what is the meaning of this quote?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?What does genetic heterogeneity mean?
- An individual comes into your genetics clinic to be tested for any anomalies. When looking at their karyotype, you notice they have three X chromosomes and a Y chromosome. What information would you be able to relay to this individual? O They have Turner syndrome, are genetically female, and have two Barr bodies per cell. O They have Klinefelter syndrome, are genetically female, and have two Barr bodies per cell. O They have Klinefelter syndrome, are genetically male, and have two Barr bodies per cell. O They have Klinefelter syndrome, are genetically male, and have three Barr bodies per cell. O They have Turner syndrome, are genetically male, and have three Barr bodies per cell.If children obtain half of their Gene's from one parent and half from the other parent, why aren't siblings identical?A cat is born with two X chromosomes and one Y chromosome. One of the X chromosomes carries the black fur allele and the other carries the orange fur allele. Would you expect this cat to be a male or female? Would it be calico?
- In the classic "X" figure of the chromosome, is the whole X from one parent, or is one side of the X from the mother and the other side from the father?Clark Kent and Lois Lane Kent are about to have a (Super) baby. As Superman, Clark possesses amazing traits, including heat-ray vision. Assume that this is: a) a dominant trait, and b) carried on the X chromosome. If Clark and Lois have a boy or a girl, what is the probability that they will possess their father's amazing abilities? (Remember: females have XX chromosomes, while males have XY chromosomes. The Y chromosome doesn’t carry any of the genes on the X chromosome). X H = Superman’s heat-ray vision allele on his X chromosome Y = Superman’s Y chromosome X h = Lois’s normal vision allele on her X chromosomeHow is it possible for humans to differ genetically from each other if we all have the same genes arranged in the same order on our chromosomes?
