Corn breeders obtained pure lines whose kernels turn sun red, pink, scarlet, or orange when exposed to sunlight (normal kernels remain yellow in sunlight). Some crosses between these lines produced the following results. The phenotypes are abbreviated O, orange; P, pink; Sc, scarlet; and SR, sun red.PhenotypesCross Parents F1 F21 SR × P all SR 66 SR: 20 P2 O × SR all SR 998 SR: 314 O3 O × P all O 1300 O: 429 P4 O × Sc all Y 182 Y:80 O:58 ScAnalyze the results of each cross, and provide a unifying hypothesis to account for all the results.

Pedigree information regarding the incidence of Tay-Sachs within a family is depicted above. The row below that indicates the genotypes of individuals II-1, II-2, and III-1 is Select one: a. II-1 II-2 III-1 Aa Aa aa   b. II-1 II-2 III-1 XAY XAXA XaXa

A family tree of sorts is called a pedigree. The symbols used for a pedigree are: female, unaffected female, affected ☐male, unaffected male, affected I 11 III 1 Pedigree Chart Minor Peta #2 Siblings are placed in hirth order from left to right and are labeled with Arabic numerals. Each generation is labeled with a Roman numeral. Therefore, the male exhibiting the trait in the pedigree below in the bottom, center would be identified as III-4. 1. Which members of the family above are affected by Huntington's Disease? 4. How many girls did II-1 and 11-2 have? 3. How many children did individuals 1-1 and 1-2 have? 2. There are no carriers for Huntington's Disease- you either have it or you don't. With this in mind, is Huntington's disease caused by a dominant or recessive trait? 5. How are individuals III-2 and II-4 related? 8 -Huntington's Disease

We are interested in detremining the genetic map of three different house finch traits: beak color (dark vs light), song length (short vs long) and patch size (reduced vs normal). We have done a large experiment involving the usual PO crossed, with the F1 test crossed. The following are the data for the offspring from the test cross: Beak Shade Patch Size Song Length Number Observed Dark Normal Long 67 Light Normal Long 3 Light Normal Short 498 Dark Normal Short 43 Dark Reduced Short 13 Light Reduced Short 80 Light Reduced Long 50 Dark Reduced Long 389 Choose the map below that best fits the data Beak Shade- 14.26CM- Patch Size- 9.54CM-Song Length O Patch Size-9.54cM- Beak Shade- 14.26CM-Song Length O Patch Size- 14.26cM- Beak Shade- 9.54CM-Song Length O Beak Shade-9.54cM-Patch Size- 14.26CM-Song Length O Patch Size-9.54CM- Song Length- 14.26CM-Beak Shade O Patch Size- 14.26cM-Song Length- 9.54cM-Beak Shade
