Elephant seals are a sexually dimorphic species of marine mammal that lives off the coast of California.

Suppose that scientists measured the weight of three adult female elephant seals and their female offspring. Parent Weight Offspring Weight 920 742 999 780 1014 787 Calculate the narrow sense heritability, h², of weight for female elephant seals to two decimal places. h²: Attempt 2 ▼ What conclusions can be drawn from these data? Both genetic and environmental factors are important in determining the weight of female elephant seals.
Sea turtles exhibit temperature-dependent sex determination, meaning that ambient temperatures control whether or not a developing turtle embryo will become male or female. The data table reflects the numbers of turtle offspring counted in Year 1 and Year 2 of a study. Male Female Year 1 180 20 Year 2 164 33 What type of test can scientists use to assess whether or not the ratio of male to female sea turtles is dependent upon the year? O ANOVA O Chi-square contingency O 2-sample t test O Chi-square goodness of fit
A gardener grows two different colors of apples under exactly the same environmental conditions. Red apples have a heritability of 0.14 for the value of apple weight, and green apples have a heritability of 0.41 for the value of apple weight. The gardener plotted the number of apples present at each weight. Which graph would you hypothesize represents the red apples? Number of apples Weight GRAPH A Number of apples Weight GRAPH B O Graph A O Graph B There is not enough information to make a hypothesis.
A species of butterfly shows variation in the length of the antennae. You measure antennae in a butterfly population and find the mean to be 15 mm. You calculate a heritability of antennae length to be 1 (h2 = 1). %3D That summer, there is a severe drought. Many of the butterflies die and only a few survive to reproduce. The surviving butterflies have a mean antennae length of 17 mm. a) What is the predicted mean limb-length of the offspring of the surviving butterflies? [ Select ] b) What type of selection was acting on antennae length in these butterflies? [ Select ] c) Five years later, you go back and measure antennae length in this butterfly population again. Every butterfly in the population has antennae measuring 16 mm. What is the heritability of antennae length in this population now? [Select ]

Make a P-generation for the two fishes below. ○ Fish 1 (Heterozygous black scales, heterozygous long tail) ○ Fish 2 (Homozygous black scales, heterozygous long tail) Then, make a Punnett square, and solve for the probability of traits that their offspring will have. Make sure that you account for both scales and tail.
There are two color morphs in boomer foxes (not a real species), red and gray. Both tend to have a single litter of 4 pups, and there is little difference in pup mortality or reproductive success between the two morphs. Red morphs tend to have their litter in their second year, and most die before 5 years old. Gray morphs tend to have their litter in their third year and most live to 10 years old. Given this information which of the following statements below is correct? Group of answer choices Gray morphs and red morphs have same relative fitness Given that the gray morphs live twice as long as the red morphs their fitness is greater Since red morphs reproduce first their fitness is greater than gray morphs Since gray morphs delay reproduction their pups are fatter
Which of the following statements is true about certainty of paternity? Question 12 options: Certainty of paternity is low when egg laying and mating occur together, as in external fertilisation. Certainty of paternity is high in most species with internal fertilisation because the acts of mating and birth are separated by time. Certainty of paternity is low when males guard females they have mated. Paternal behaviour exists because it has been reinforced over generations by natural selection
The table shows concordance for height between monozygotic and dizygotic twin pairs from birth to the age of eight years. A concordance of 1 indicates that the twins are identical in height. Concordance for height between Age monozygotic twin pairs dizygotic twin pairs of the same sex Birth 3 months 6 months 12 months 24 months 3 0.62 0.79 0.78 0.72 0.80 0.67 0.66 0.54 0.86 0.89 0.93 0.56 years 5 years 0.94 0.51 8 years 0.94 0.49 (a) If height were entirely genetically controlled, what concordance would you expect between monozygotic twin pairs? Explain your answer. (b) Does data for eight-year-old twins suggest that height is largely controlled by genetic factors? Explain you answer.
