DIRECTIONS: Reаd the pаssаge. Then read the questiоns and answer Y (yes) оr N (nо).Two Types of TwinsThere are two types of twins: identical and fraternal. Both types of twins are born at the same time and have the same mother. Identical twins are more similar than fraternal twins because they are from the same egg. The egg divides into two parts, and the twins then develop separately. Identical twins are always the same gender, either boys or girls. They look almost the same, though there are some small differences. They have the same blood type, and their fingerprints are similar. Fraternal twins are born at the same time but are from two different eggs. Fraternal twins may be of different genders. They may look similar, but no more than brothers or sisters born at different times do.In the United States, about one birth in 87 is a twin birth, either identical or fraternal. Identical twins are very unusual. Fraternal twins are more common than identical twins. They occur about four times more often. Do fraternal twins have the same fingerprints?
