Water wisteria is an aquatic plant that is easy to care for and reproduces very quickly. A small man-made pond of 350 L contains 78 water wisteria plants. 15 new plants are introduced daily to the pond, while 50 plants are taken out once a week to be sold at local pet shops. The water wisteria plants reproduce at a rate of two plants per day. 

The agouti gene determines coat colour in mice. Heterozygous mice have yellow coats, while homozygous dominant mice have black coats. However, having two copies of the recessive alleles is lethal. In a population of 2 000 mice, 1 082 mice have black coats. Calculate the frequency of each allele. Show all your work and express your answer as a value between 0 and 1 rounded to two decimal places. (3 marks) What percentage of the mouse population is expected to be carriers of the lethal allele?

In mice, the waltzing allele (w) that causes the mouse to run in circles due to an inner ear defect is recessive to the non-waltzing allele (W). In an ideal mouse population exhibiting Hardy–Weinberg equilibrium of 150 mice, 15% of the alleles are non-waltzing. What is the frequency of the recessive allele? Record your answer as a whole number percentage.
