Choose one human multifactorial condition and describe it in detail. Include a description of the condition, possible genetic and environmental components that cause the condition as well as an explanation of why it is difficult to study multifactorial conditions. Include references.

"evolution is an integrated process" and uses sickle-cell allele as an example. In just 2-3 sentences, trace the various factors that influence evolution based on this example. I just want to know how Darwin, Mendel, gene flow, genetic drift, mutation, recombination and even the environment serve to create evolution. Thank you.

- Explain: "Mutation is random;natural selection is the very opposite of random"arrow_forwardAccording to the Hardy-Weinberg Equilibrium Equation, all of the following slow down or stop evolution EXCEPT (choose as many as apply): Group of answer choices very small population very large population no one leaves or comes into the population everyone has equal numbers of offspring there are no mutations there are lots of mutations there is non- random matingarrow_forwardWhich of the following are true about human variation? (Choose all that apply): Group of answer choices Genotype refers to how a person looks, through interaction of genes and environment. Siblings are more like each other, genetically, than they are to either of their parents. Usually, it is only identical twins (or sometimes triplets or other multiple births) who have identical DNA, and even so, there is still some phenotypic variation between them. You could have genes for being tall, but if your mother (or even grandmother) had poor nutrition during fetal gestation, you could be shorter than your genes allow. You can produce taller offspring by stretching and remembering to stand up as tall as you can.arrow_forward
- Describe natural selection and give an example of natural selection at work in a population. Please elaborate or explain in 10-15 sentences, please?arrow_forwardWhich of the following statements describe how genes, proteins, and traits are related? Select all that apply. Proteins carry out activities in the cell that affect traits. Genes carry out functions in the cell that include providing structure and controlling chemical reactions. Genes contain information about traits. The nucleotide sequence of a gene determines the amino acid sequence of a protein. Proteins are molecules in the cell that encode genes. Submitarrow_forwardWhich of the following statements best characterizes genetic diversity in humans? 1.) There are far more genetic differences between populations/groups than there is variation within populations. 2.) Between-group differences in most phenotypic traits (e.g., athletic ability, performance on standardized tests, etc.) are mostly inherited and due to the effects of natural selection. 3.) The vast majority of polymorphisms (such as SNPs) in the genome are informative about a person's ancestry (in other words, you could get a pretty good idea of someone's ancestry by looking at their genotype at just about any random SNP in the genome). 4.) Humans have much lower levels of genetic diversity than most other animals.arrow_forward
