is produced resulting in yellow hair You want to breed Labrador retrievers and you cross a true breeding brown Labrador retriever to a true breeding yellow Labrador retriever All 15 of the F1 puppies are black After the puppies grow up you cross two of the F1 black dogs together In the F2 generation you get 8 black puppies 4 yellow pupples and 3 brown puppies Part 1 What is are the possible genotypets of the true breeding brown lab in the P generation Obble Brown ObbEE Obbee Could be either answer bbEE or bbfe Incorrect Since the questions states that the dog is true breeding it must be homozygous for both genes Part 2 What is are the possible genotype s of the true breeding yellow lab in the P generation Obbee SO OBbee OBBee Could be either bbee or Bbee O Could be either Bbee or BBee Could be either bbee or BBee All of the genotypes shown are possible Incorrect The offspring of this cross are all black If the yellow parent doesn t have a 8 allele the offspring cannot be black Part 3 What is are the possible genotype s of the yellow puppies in the F2 generation Select all that apply Bbee bbee Bble bble 884 Incomect The Bble genotype leads to a black phenotype because of the dominant 8 and E alleles M The bble genotype leads to a brown phenotype because of the recessive b allele and the dominant allele Part 4 You have a friend who wants to breed only brown Labrador retrievers She wants a true breeding brown puppy from your 12 litter Approximately how many of your 3 brown puppies from the F2 are true breeding X

gene HH and Hh hamsters have hair and hh hamsters are hairless Multiple EeHh hamsters are mated together generating 400 progeny altogether Note that this is a different cross from the one discussed in Video 3 4 modeling use of Chi squared analysis to test for linkage here we have a cross between two dihybrids rather than a cross between a dihybrid and a tester Therefore the null hypothesis that E and H genes are unlinked will yield different expected values here compared to the testcross scenario when two dihybrids are crossed together and the genes are unlinked what proportion of each of the four progeny classes do we get Part 1 If the E and H genes are unlinked how many of the 400 progeny hamsters would you expect to be hairless and normal size 50 O 75 100 O225 150 Part 2 You perform the cross described above and get the results shown below Note that this problem uses a short hand convention you will want to get used to if a mutant phenotype is not mentioned assume it is absent Therefore assume that the progeny described below as hairless have normal body size Assume that the progeny described as dwarf have hair Hairless dwarf 33 Perform a chi square analysis for this cross testing the hypothesis that the E and H genes are unlinked using the chi square table below 1 Degrees of freedom 2 3 Wild type 212 Hairless 82 4 Dwarf 73 5 O 3 41 O 1 26 16 08 p 0 99 O 0 75 0 000157 0 020 0 115 0 297 0 554 0 95 0 00393 0 103 0 352 What is the total chi square value Round to two decimals 0 711 1 145 0 80 0 0642 0 446 1 005 1 649 2 343 0 50 0 455 1 386 2 366 3 357 4 351 0 20 1 642 3 219 4 642 5 989 7 289 0 05 3 841 5 991 7 815 9 488 11 070 0 01 6 635 9 210 11 345 13 277 15 086

You will learn about the three domains of development physical cognitive and psychosocial and how they change across the lifespan It is important to keep in mind that these domains are multidimensional That is each of these areas overlaps and interacts Take a physical milestone of infancy for example crawling Compared to a less mobile baby a crawling baby is able to explore her environment actively seeking out and investigating toys and objects which contribute to gains in cognitive development At the same time parent child interactions change which have important consequences for psychosocial development Adults often celebrate these milestones with reinforcement hugs clapping exclamations Good job etc while also setting limits in order to protect the curious inexperienced baby Parents are frequently observed redirecting their babies physically moving them from potential hazards and using verbal prompts such as No no Select an important developmental milestone You may choose any age range and the milestone can be physical cognitive or psychosocial Examples could include learning to talk read run memorize add subtract etc Milestone What type of milestone is this Physical Cognitive Psychosocial Summarize the importance of this milestone in the person s development Explain how meeting this milestone contributes to changes in the other two domains of development
