This Concept Map, created with IHMC CmapTools, has information related to: Development Wyatt Ch 3 092818 Final, social / biotic ("nurture") for example Imprinting in ducklings, Regulatory Mechanisms act to determine Gene Expression, bonding with the newly born lamb with the adaptive function / current utlity, the hypothalamus to secrete hormones sending signals to the pituitary, Methylation of DNA leading to "down-regulation" of (decrease in) Transcription (making of proteins encoded by the methylated DNA) (see "Genetic Regulatory Mechanisms"), Gene Expression for example The "SrY" gene (turned on early in development in mammals), physical / abiotic for example Phylsical Stresors in the environment, Histone Acetylation Which Loosens Chromatin; Increases Transcription, "Transgender" Changes in Coral Reef Anemone Fish in which If the female dies, the largest male becomes the female, The "SrY" gene (turned on early in development in mammals) determines whether an individual becomes male or female (interestingly, we all start out embryologically as females), FoxP2 Gene determining song-learning in non-human mammals (whales & dophins), Internal Physiological Factors (not genetic) including female sheep giving birth, Imprinting in ducklings requires hearing the other embryo ducklings while in the egg, female sheep giving birth during which the expanding vagina & cervix, the duckling to the mother's quack once they are hatched with the adaptive function / current utlity, The development (ontogeny) of an animal's behavior with Natural Selection, mimcking her actions with the adaptive function / current utlity, the development song in young birds that sing (not all birds sing) but for which "exon 7" (expressed codon 7) seems to be unique for each of these groups (humans; whales & dolphins; birds) (which could lead to slightly different proteins in the 3 groups) (Webb & Zhang 2005), hearing the other embryo ducklings while in the egg sensitizing the duckling to the mother's quack once they are hatched, DNA (genetics / heredity) upon which Regulatory Mechanisms act
