People who suffer from blinky syndrome blink their eyes rapidly when they look at bright lights. In order to draw a pedigree chart for this family, you interview Mike and Annie. Neither suffer from this syndrome. Annie’s mother is normal, while Annie’s father blinked like crazy at bright lights. Annie has one sister and one brother and both of them are unaffected. While Annie’s sister has yet to have kids, her brother married a blinky sufferer. Mike’s mother is a blinker while his father is normal. Mike’s brother is just like their mother. In addition, this brother married a blinker. Mike’s sister is normal - as is her husband and their one boy. Draw a pedigree chart below in order to answer the following on the next page. Use the letters A and a for the genotypes. If more than one genotype is possible for an individual - you may write it as A with a…You have been hired to produce a family tree for three generations of a family where a disorder called “blinky” syndrome is observed.
