Population Genetics / Hardy-Weinberg Problems Directions: Work out the following problems on a separate piece of paper. Show ALL work and circle your answers. 1) If the frequency of a recessive allele is 30% in a population of 100 people‚ how many would you predict would be carriers of this allele‚ but would not express the recessive phenotype? q= 0.30 p= 0.70 Carriers = 2pq = 2(.3)(.7) = .42 #= (.42)(100) = 42 individuals 2) From a sample of 278 American Indians‚ the following MN

The study of fossils is helpful to know in understanding evolution‚ as it teaches us about our past‚ including common ancestors. Evolutionary biology deals with the study of changes in organisms in a population. ( 6 ) This will help with the analysis in similar (vestigial) structures in organisms‚ homologous structures‚ and population genetics. Developmental biology mainly studies an embryo‚ once fertilized‚ through growth. The comparison between embryos is most helpful in this situation due to the fact there are many similarities between embryos as they

about 20 days‚ thus are the models for relating sex-linked inheritance. Obviously it is not the breeding ways of the Drosophila that is being examined in this experiment‚ but the developing offspring‚ and their phenotypes. The phenotype is based on the wing shape and the eye color‚ which is resulted by grouping of genes

Concept Check 14.1 C O N C E P T C H E C K 14.1 1. Pea plants heterozygous for flower position and stem length (AaTt) are allowed to selfpollinate‚ and 400 of the resulting seeds are planted. Draw a Punnett square for this cross. How many offspring would be predicted to have terminal flowers and be dwarf? (See Table 14.1.) 1. According to the law of independent assortment‚ 25 plants (1⁄16 of the offspring) are predicted to be aatt‚ or recessive for both characters. The actual result is likely

CHAPTER 14 1. Norm of reaction: the phenotypic range that a genotype is associated with due to environmental influences. 2. Multifactorial: characters that have many factors‚ both genetic and environmental‚ collectively influence phenotype. 3. Pleiotropy: when a gene controls multiple phenotypic effects 4. Epistasis: When a gene at one locus alters the phenotypic expression of a gene at a second locus 5. Carrier: a person who is heterozygous for a recessive disease and therefore

A phenotypic ratio of 9:3:3:1 was hypothesized with wrinkled wings and wild type body: wrinkled wings and black body: wild type wings and body wing: wild type wings and black body correspondingly. A p-value<0.01 was obtained from a Χ2=23.24 thus rejecting the hypothesis. Observed data gave a 5:3:2:1 phenotypic ratio of wrinkled wings: wrinkled wings and black body: wild type wings body: black body respectively yielding these values. A BLAST search on the black mutant
