explain
In flying pigs, genes for wing length (S = long wings, s = short wings) and body color (P=gray; p = pink) are 24 map units apart. You are crossing a dihybrid male pig (created by crossing a pure-breeding short-winged gray pig with a pure-breeding long-winged pink pig) with a pink, short-winged female pig. For the questions that follow, where appropriate, do not do the math -- report individual chances and mathematical operators. Are the male pigs alleles in...

Question 2 2 marks A population is normally distributed with an unknown mean μ and unknown standard deviation σ. You collect a random sample of 24 measurements with sample mean7-55.9 and standard deviation-7.53. Use this information to answer the questions below (a) [0.5 mark] What is your 95% confidence İnterval for the population mean μ? (b) [1 mark] what is your best estimate for the population standard deviation σ? (c) [0.5 mark] If a fellow enginer tells you that the...
