| Video Discription | Here are the key terms with explanations for this section. Thanks for watching! Genes: Genes are segments of DNA that carry the instructions for building and maintaining the various components of living organisms. They play a crucial role in determining an individual's traits and characteristics. Chromosomes: Chromosomes are structures within cells that contain the genetic information, including genes. Humans have 46 chromosomes arranged in 23 pairs. Genome: The genome refers to the complete set of genetic material within an organism. It includes all the genes and non-coding sequences of DNA. Single Gene Inheritance: This refers to the inheritance pattern where a trait is determined by a single gene. Traits such as certain diseases or genetic disorders can be inherited in this manner. Polygenic Inheritance: Polygenic inheritance involves multiple genes influencing a single trait. This is common for complex traits like height or intelligence, where the interaction of multiple genes contributes to the final outcome. Heritability: Heritability is a statistical concept that quantifies the proportion of variability in a trait within a population that can be attributed to genetic factors. It does not indicate the degree to which an individual's traits are influenced by genetics. Monozygotic Twins: Monozygotic twins, also known as identical twins, originate from a single fertilized egg that splits into two embryos. They share nearly identical genetic makeup. Dizygotic Twins: Dizygotic twins, also called fraternal twins, develop from two separate eggs fertilized by two different sperm cells. They share approximately 50% of their genetic material on average, just like regular siblings. Twin Studies: Twin studies involve comparing the similarities and differences between monozygotic and dizygotic twins to investigate the role of genetics and environment in various traits. Adoption Studies: Adoption studies examine the influence of genetics and environment by comparing adopted individuals with their biological and adoptive families. This helps tease apart the contributions of genes and upbringing. Darwin: Charles Darwin was a naturalist who formulated the theory of evolution by natural selection. His work revolutionized our understanding of how species adapt and change over time. Evolutionary Psychology: Evolutionary psychology explores how human behavior and cognitive processes have evolved to adapt to our ancestral environment. It seeks to understand how certain behaviors might have provided an evolutionary advantage in the past. #appsychology #evolutionarypsychology #psychology [MAndoGLpKcw] |
