Item 40: Question A recessive allele in mice results in an abnormally long neck. Sometimes, during early embryonic development, the abnormal neck causes the embryo to die. An experimenter began with a population of true-breeding normal mice and true-breeding mice with long necks. Crosses were made between these two populations to produce an F1 generation of mice with normal necks. The F1 mice were then mated to each other to obtain an F2 generation. For the mice that were born alive, the following data were obtained: 693 mice with normal necks 48 mice with long necks What percentage of homozygous mice (that WOULD HAVE HAD long necks IF they had survived) died during embryonic development? Please enter only the number and do NOT include the percent symbol in your answer. For example for 45.8439% just enter "45.8". Submit Submit and Next Mark this question for later review. (3 pts.) %
