Farmer John decides to increase the weight of the eggs produced by his chickens. The average weight of his eggs is 10 grams. He knows that the heritability of egg weight is 0.5. He selects for chickens producing eggs that are 18 grams. The expected average weight of the resulting eggs is:

13-15 grams...

Explanation:

If only 50% of weight genes are transferred as seen in 0.5 probability then the ideal weight will be 14 grams (9 grams from first and 5 grams from the 2nd and so... ). But due to the genetic anomalies the range should be taken as 13-15 grams with a confidence interval of 95%...

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

what are the awnser choices? i mean, without choices, it is an incompleat
