The muscles of the neck that are used to look both the ways to cross a street. Introduction: The muscles that are involved in flexing the neck and head are found in pairs on the lateral and anterior surfaces of the neck. The muscles that are involved in extending the head and neck are found in the posterior surface of the neck. The muscles that are involved in the movement of the head and neck include scalenes, sternocleidomastoid, trapezius, and splenius capitis.

Show your calculations. (2 pts) (b) Is this population in Hardy-Weinberg equilibrium? Show your calculations. (3 pts) 12pt v Paragraph BIU UA AV & VT2V f CO V

In a natural population of outbreeding plants, the variance of the total number of seeds per plant is 16. From the natural population, 20 plants are taken into the laboratory and developed into separate true-breeding lines by self- fertilization-with selection for high, low, or medium number of seeds-for 10 generations. The average variance in the tenth generation in each of the 20 sets is about equal and averages 5.8 across all the sets. Estimate the broad-sense heritability for seed number in this population.
