General
This is what it meant to be in reproductive conflict
Is it when an older mother and younger mother are reproducing at the same time?
Define fecundity
Is it the potential reproductive capacity of an individual or population, often measured as the number of offspring produced?
This is the trend of local relatedness after whale menopause.
Is local relatedness decreasing?
This is why mean relatedness to local whale females remains constant with age
Is it because females are born into their mother's group and already have high local relatedness to other local females at birth?
Define inclusive fitness
Is it an individual's success in passing on its genes not only through its own offspring but also through aiding the survival and reproduction of genetically related individuals, such as siblings or offspring of relatives?
This is the relationship between birth order of calves and survival
The killer whale population has this kind of dispersal and mating
What is no dispersal and non-local mating?
Define alloparental care
Is it care by another individual who is not your parent?
This is how the reproductive conflict hypothesis adds to the grandmother hypothesis.
Is it that post-reproductive helping is not enough to explain selection for menopause and the reproductive conflict hypothesis adds the element of competition to explain the timing of menopause?
This is the time period that the study defines as intergenerational reproductive overlap
Is it the birth of another calf within two years of the birth of a grandoffspring/sibling
Define kinship dynamics in context
are kinship dynamics age-related changes in local relatedness that influence reproductive competition between younger and older females?
