These are recessive X-linked traits. The male has only one copy of the X chromosome, and the female has two copies. So the male will express the traits if he has the genes, and the female is merely a carrier, if she has only one copy of the…

Q: What phenotypes and phenotypic ratios would you expect in a cross of a pink flowered and a red flowered snapdragon (pink color in snapdragons shows incomplete dominance)? a.1 red : 1 pink b.3 pink : 1 red c.3 red : 1 pink d.1 white : 2 pink : 1 red Using standard conventions for naming alleles, which of the following pairs is correct? TT – heterozygous tt – homozygous recessive tt – dominant phenotype Tt – recessive phenotype Which of the following represents the possible genotypes of the offspring resulting from a cross between an individual homozygous dominant for black hair (BB) and an individual homozygous recessive for blonde hair (bb)? BB, Bb and bb BB or Bb BB only Bb only What are the possible phenotypes of the children if the mother has Type A blood and the father has type AB blood? A or B A, B, or O A, B, or AB all AB What are the predicted phenotypes for the female children from the union of a woman who is heterozygous for hemophilia and a man who has normal blood clotting characteristics (the gene for hemophilia is located on the X chromosome)? 1 hemophilia : 2 homozygous normal : 1 carrier all carriers 3 homozygous normal : 1 carrier 1 homozygous normal : 1 carrier

A: I’ll be putting some Punnett squares below to help with answers. You’ve got to use your imagination on them, as it’s hard to put them on here without the actual boxes with lines…For the first question, it would be A. Using a Punnett square, the following occurs: R R’R RR RR’R RR RR’This gives you two red and two pink, or 1:1 ratio.*****Question #2: B. Lower-case letters usually denote recessive genes, and since there are two of them, that denotes that it’s homozygous. If there was a capital and a lowercase, that would be heterozygous.*****Question #3: D. Using a Punnett square, you get this: B Bb Bb Bbb Bb BbThe only thing you can get are heterozygous Bb’s.*****Question #4: C. Using a Punnet square, you can show where you cannot get any phenotypic O’s, but could get A, B, and AB.: A OA AA AOB AB BOor A AA AA AAB AB ABThe mother can display type A blood by either having AO (as in the first square) or AA (as in the second). No pure type O’s can be made, so no offspring could display type O. Remember that an AO displays as an A type, and a BO displays as a B type.*****And lastly, question #5: D. Again, a Punnett square to show that you’d get one female that’s normal and one that’s a carrier (remember that females are XX, so you’ll ignore the XY’s for this one): Xnorm XhemoXnorm Xnorm X norm X norm X hemoY X norm Y X norm X hemo

Q: What are the predicted phenotypes of the male children from the union of a women who is heterozygous for hemophilia and a man who has normal blood clotting characteristics?

A: Hemophilia is sex-linked, carried on the X chromosome.The hemophilia chromosome appears as “x”.heterozygous female is Xx (carrier female, unaffected)normal male, XY (normal male, healthy)Therefore, all females from this union would be either XX or Xx.All males from this union would be either XY or xY.So, 50% of the males would be healthy normal, 50% would be affected.
