Consider two genes that are independent, the a gene and the b gene. each gene has two alleles (a gene: a1 and a2, b gene: b1 and b2). the frequency of a1 allele at the a gene is 0.29 and the frequency of the b2 allele at the b gene is 0.42. what is the probability of an individual in a randomly mating population of having a1a2b1b2 as their genotype?

Astudent observes a star from two positions of earth in its orbit, in summer and winter, and measures the change in the position of the star. which of these can be best calculated by this method?

Zoe decided to measure the hand length of each of her classmates. first she marked a line across each student's wrist and lined up a ruler from this mark to the top of the middle finger to measure the length. then she recorded the measurements in the table below. marla did this the same way for each classmate, and then zoe used this ruler to measure each straight line and record the data below. this data is invalid. what is the most likely reason why it is invalid? the ruler is marked in centimeters, but zoe recorded data in inches. the range of lengths is too wide, so zoe must have misread the ruler. marla’s complicated measuring procedure was overly confusing. marla could have been inconsistent while drawing outlines of fingers.
