A Punnet square is a grid used to show possible combinations for the offspring of two parents. In the Punnet square shown a boy is shown by XY and a girl is XX. Complete the Punnet Square and explain why having a girl or a boy is equally likely.
XX, XX, YY, YY because there are two chances for both to happen.
XY, XY, XY, XY because there are two possible outcomes for both a boy and a girl.
XX, XX, YY, YY because there are two possible outcomes for both a boy and a girl.
XX, XX, XY, XY because there are two possible outcomes for both a boy and a girl.
