Could this work :confused: Selection Differential(difference between the mean phenotype of the selected parents and the mean phenotype of the population before selection) 1.02g-.88g= .14g Selection Response(Amount phenotype change in one generation) .96g-.88g=.08 g then divide the...

Hi, My Question: Assume that all phenotypic variance in seed weight in beans is genetically determined and is additive. From a population in which the mean seed weight was 0.88g, a farmer selected two seeds, each weighing 1.02g. He planted these and crossed the resulting plants to each...

Hi, I just found another way but it still uses sine and also finds how I came up with the 49 degrees. What I did was first find the critical angle for the light leaving the water n(water)*sin(theta)=n(air)sin(theta) 1.33sin(theta)=1*sin(90) where I found theta to be 48.8 I used...

Hi, My Question: A beam of light is emitted in a pool from a depth of 62.0 cm. Where must it strike the air-water interface, relative to the spot directy abovie, in order that the light does not exit the water? My Work Tan(49)=(x/62.0cm), got 49 degrees from the textbook where...

Hi, My Question: Problem 1. The expected phenotypic ratios for each of the crosses below is 1:1. Determine whether the observed ratios are differ significantly (p < 0.05) from the expected. I used a Chi Square test to help me determine that answer and found the there is no probability of...

Hi, So it would be a 9:3:3:1 type combination? If so wouldn't it be the same answer for the different type of combinations for this cross r/rP/P´R/rP/p

So you mean like this

Hi, My Question: In poultry, the dominant alleles for a rose comb (R) and a pea comb (P), if present together, give a walnut comb. The recessive alleles of each gene, when present together in a homozygous state, give a single comb. What will be the comb characters of the offspring of the...

Opps:blushing: Wouldn't it be X-linked recessive since it couldn't be x-linked dominant otherwise one of the parents would of had it, right? Also for these questions: What is the probability that III-2 is a carrier( heterozygous)? Answer: 50% If III-3 and III-4 marry, what is the...

My Question: What is the mechanism of inheritance for the trait? Which people in the pedigree are known to be heterozygous for the trait? What is the probability that III-2 is a carrier( heterozygous)? If III-3 and III-4 marry, what is the probability that their first child will have the...

Found this it might help a little:smile: http://www.elmhurst.edu/~chm/vchembook/604glycogenesis.html

Hi, Question Some rearvier mirrors produce images of cars behind you that are smaller than they would be if the mirror were flat. Are the mirrors concave or convex? What is the mirror's radius of curvature if cars 20.0 m away appear 0.33x their normal size. My Answers The mirrors are...

I thought it was 20% because 1/5 is .20 multiply that by 100 and you get 20%, but I know what I did wrong this time all I have to do is use the binomial equation. P=((n!)/(x!(n-x)!))*((p^x)(q^(n-x))) I used the following steps to come up with an answer Step 1: Calculate the individual...

Sorry about the link :blushing: http://www.spsu.edu/math/edwards/1113/unitcircle.htm http://www2.spsu.edu/math/edwards/1113/inverse.htm Try both, they work now. :smile:

The probability of having 1 child having blue eyes is 20% right, so to figure the probability of three children having blue eyes would be P(blue)=(1/5)^3 or .80 % Is this correct?
