Stubble bristles (Sb) is dominant to wildtype bristles (Sb⁺) in Drosophila melanogaster. In a population where there are 137 flies with wildtype bristles and 836 flies with stubble bristles, what are the allele frequencies for the Sb and Sb⁺ alleles (assuming the population is in Hardy-Weinberg equilibrium)? Please calculated your answers to 3 decimal places.

f(Sb)=

f(Sb⁺)=

If the population is in Hardy-Weinberg equilibrium, what proportion of the population would you expect to be heterozygous?

The purpose of this question is to develop a web page to determine if two line segments represent the diagonals of a square or not. The first line segment L1 is bounded by the two points (x1, y1 ) and (x2, y2 ) while the second line segment L2 is bounded by the two points (x3, y3 ) and (x4, y4 ).

Keep in mind that the lengths of the diagonals of a square are equal and bisect each other at right angles. So you need to find the length, slope and midpoint of each line segment in order to determine if they represent the diagonals of a square or not. Remember that two line segments are perpendicular if the multiplication of their slops equals -1.

In this question you might need to search for formulas in some math textbooks or in the e-library to calculate the slope, x coordinate and y coordinate of the midpoint and length of a line segment.

The web page should be implemented by using HTML tags and PHP codes.

The designed web page should include a title, a header, an input form for entering the values of the four points, only numerical values, and an output form for presenting the slopes, lengths, midpoints of the two line segments and the error messages if any. The design and the layout of the web page are left intentionally for the student to distinguish his/her TMA form other students and to show his/her creativity in designing the web page.

The PHP part should include at least four PHP functions; three functions for calculating the slope, coordinates of the midpoint and the length of a line segment. And another function for determining if two line segments represents the diagonals of a square or not.
