Number the sequence of events that are responsible for initiating labor: 1. The hypothalamus of the mother and fetus stimulates the placenta to secrete prostaglandins. 2. Fetal cortisol levels increase andstimulate the placenta to release estrogen. 3. Prostaglandins and oxytocin stimulate the uterus to contract. 4. Estrogen stimulates the myometrium to form oxytocin receptors. Introduction: Parturition is the process where the fetus is expelled out of the mother’s body from the uterus through the vagina. It occurs in a sequential manner which is called labor. It usually occurs at the end of 39 weeks with a variation of 1-2 weeks. Premature births can cause the development of several complications in the child.

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.

Question 1 In a population of Jackalopes (pictured below), horn length will vary between 0.5 and 2 feet, with the mean length somewhere around 1.05 feet. You pick Jackalopes that have horn lengths around 1.75 feet to breed as this appears to be the optimal length for battling other Jackalopes for food. After a round of breeding, you measure the offsprings' mean horn length is 1.67. What is the heritability of horns length (h2)? Is Jackalope horn length a heritable trait?
