Elephant seals are a sexually dimorphic species of marine mammal that lives off the coast of California. The females, which weigh around 1000 lbs, are much smaller than the males, which may weigh up to 5000 Ibs. 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, h', of weight for female elephant seals to two decimal places. What conclusions can be drawn from these data?

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
