17. In rats, the following genotypes of two independently assorting autosomal genes determine coat color.A_B_ (gray)A_bb (yellow)aaB_ (black)aabb (cream)A third gene pair on a separate autosome determines whether or not any color will be produced.The CC and Cc genotypes allow color according to the expression of the A and B alleles.However, the cc genotype results in albino rats regardless of the A and B alleles present. Given the inheritance pattern of coat color in rats described in Problem 17, predict the genotype and phenotype of the parents who produced the following offspring: (c) 27/64 gray: 16/64 albino: 9/64 yellow: 9/64 black: 3/64 cream
3. Short-tailed pup distribution. In mice, the dominant T allele results in a short tail. Homozygous T/T genotype is lethal, which means mouse embryos with this genotype die before they are born. Homozygous t/t is normal, with normal tail. A cross between two short-tailed mice produces a litter of 5 pups. a). What are the genotype(s) of the two short-tailed mice used in the cross? b). What are the possible genotypes and phenotypes of the 5 pups? What are their perspective ratio?
1. Strong Avengers (Earth's Mightiest Heroes) who normally have tall stature (+), long hair (+), and love hammers (+). But three recessive mutations showed up (likely due to gamma radiation) that result in short statured (ss) Avengers that have short hair (sh) and are allergic to hammers (ah). Data from a three-point testcross are shown below: Phenotype Genotype # Scored Normal + + + 351 Short statured Ss + + 81 Short hair 39 Allergic to hammers + + ah 4 Short statured, rounded ears 1 Short statured, allergic to hammers ss + ah 45 Short hair, allergic to hammers + sh ah 78 Short statured, short hair, allergic to hammers ss sh ah 401 ТОTAL 1000 (a) List the genotypes that are blank in the Table.

3) In the snail Capaea nemoralis, an autosomal allele causing a banded shell (B®) is recessive to the allele for an unbanded shell (B°). Genes at a different locus determine the background color of the shell; here yellow (C') is recessive to brown (CBw). A banded, yellow snail is crossed with a homozygous brown, unbanded snail. The F1 are then crossed with banded, yellow snails (a test cross). a. What will the results of the testcross be in the loci that control banding and color ARE linked with NO crossing over.
1. A woman with type B blood gives birth to a girl who is type O. Which of the following men could of been the father (a) Joe- Type O (b) Frank -Type B (c) Steve- Type AB (d) both Joe and Frank (e) Joe, Frank or Steve In mice, coat color is due to the inheritance of three genes located on three different chromosomes. The A gene which determine if a yellow band is present on the hair (A= yellow band, aa=no yellow band ) and the B gene which determines if the hair is brown (bb ) or Black (B). The A and B genes interact to produce the following coat colors: Agouti: AB Cinnamon: A bk black: brewn aabb The third gene is the C gene, which determines if the mice has any hair pigment at all. If the mouse has at least one C allele then the coat color will be determined by the A and B genes as described above. However, if the mouse is cc in genotype it will be albino, regardless of the mouse's A and B genotype. aaB 2. In mice coat color (a) the C gene is dominant to the A and B genes (b) the cc…
7) In cats, the gene for coat color is both X-linked and incompletely dominant. There are black coat and yellow coat alleles, with calico (tortoise shell) as the heterozygous form. If a yellow male mates with a calico female, what are the expected offspring phenotypes (in percent)? hbit
4. Hemophilia in cats is X-linked recessive. (And yes, cats' sex chromosomes work the same way peoples' do.) A carrier lady cat marries a hemophilic man cat. a) Draw a Punnett square showing this, and showing offspring genders and genotypes. Hint: you must draw the correct type of Punnett square for an x-linked problem to get the right answer. b) What fraction of their boy kittens will be hemophilic? c) What fraction of their girl kittens will be hemophilic? d) What fraction of all their kittens will be hemophilic? e) A daughter from this marriage grows up and gets married to a hemophilic tomcat. All of their kids are hemophilic. What was the genotype of the daughter?
3) In the snail Capaea nemoralis, an autosomal allele causing a banded shell (B®) is recessive to the allele for an unbanded shell (B°). Genes at a different locus determine the background color of the shell; here yellow (C") is recessive to brown (CBw). A banded, yellow snail is crossed with a homozygous brown, unbanded snail. The F1 are then crossed with banded, yellow snails (a test cross). b. What will the results be of the testcross be if the loci assort independently?
9.) In humans, when a dark-skinned person reproduces with a very light-skinned person, their children may range in color from dark to brown. This occurs because skin color is controlled by more than one gene (the exact # of genes is not known). For your convenience, a table is presented below that shows several possible genotypes & phenotypes: Genotypes Phenotypes AABB Very dark skin AABb or AaBB Dark skin AaBb, AAbb, or aaBB Medium brown skin Aabb or aaBb Light skin aabb Very light skin If a man with dark skin whose genotype is AaBB reproduces with a woman who has light skin (aaBb), what are the possible skin colors that their children will have? Develop a Punnett square and list the possible genotypes & phenotypes.

3) In the snail Capaea nemoralis, an autosomal allele causing a banded shell (B³) is recessive to the allele for an unbanded shell (B°). Genes at a different locus determine the background color of the shell; here yellow (C) is recessive to brown (CB"). A banded, yellow snail is crossed with a homozygous brown, unbanded snail. The F1 are then crossed with banded, yellow snails (a test cross). С. What will the results be of the testcross if the loci ARE linked and 20 m.u. apart?
