Thus, it will be necessary to build only 30 ft of the wall forms, but 90 ft of forms must be erected and removed. Plyform sheets will be used for sheathing and dimension lumber will be used for studs and wales. A material supplier quotes these prices: $.55/bf for lumber, $34/sheet for 4-ft by 8-ft Plyform, $2.31/lb for nails, and $14/gal for form oil. Carpenters cost $28/hr, laborers cost $21/hr, and foreman cost $32/hr. Use 1 foreman for 4 carpenters. The average quantity of form materials are: 15 lb nail/1,000 bf lumber for the first use, 10 lb nail/1,000 bf lumber for reuses, 400 SFCA/gal for oil, 18 ties for 100 SFCA. a.

In dаmselflies, аssume thаt straight antennae (S) are dоminant tо bent antennae and that lоng wings (L) are dominant to short wings.The genes for antennae shape and wing length are on different chromosomes. Two damselflies mate; one is true-breeding for straight antennae and long wings, the other is true-breeding for bent antennae and short wings. Two of their F1 progeny mate. What gametes will be made by each of the F1 individuals? [gametes] What is the probability that an F2 offspring will be will have the recessive parental phenotype? [nonrecombinants]
