pirah 3 years ago find out the possible blood groups and genotypes of the children of following parents:(a)Mr.x=O group Mrs.x=B group (b)Mr.y=A Mrs.y=AB (c)Mr.z=A Mrs.z=A

• This Question is Open

Please wait for few minutes. I am posting the complete details.

2. pirah

ok

Answer (a): Father's blood group = "O" Group Mother's blood group = "B" group

Father's possible genotype: |dw:1334298633463:dw| Mother's possible genotype: |dw:1334298658444:dw|, and also |dw:1334298679874:dw|

During crossing, child's possible genotypes are : |dw:1334298831218:dw|(in all cases)

Answer (b): Father's Blood Group: "A" group Mother's Blood Group : "AB" Group

Father's Genotype: |dw:1334299040437:dw|, and also |dw:1334299090924:dw|

Now, mother's genotype: |dw:1334299220831:dw|

Child's possible genotype: |dw:1334299524607:dw| and also|dw:1334299558381:dw|

cross kaise karengen mje method btae yhi nhn a rha

Ji suniye. I am posting the diagram.

12. pirah

ok

|dw:1334299898020:dw| This is just a sample I have shown.

14. pirah

ok thank u bhai

Welcome Didi. Mujhe medal to dijiye na. Please!!!!!!!!!!!!!!!!!!

16. pirah

ok ji

Thanks Didi

18. pirah

u welcom bhai

19. pirah

bhai ek bat kahun plzz dont mind

Ji kahiye.

21. pirah

mje abi tak thk se samjh nhn aya

Oooooooooooooooo. Yeh to badi dukh ki baat hai!!!!!!!!!

23. pirah

32. wasiqss

5 years pehle parhi thi bhol gaya sorry

33. pirah

ok

34. pirah

yahn to bio ka koi h hi nhn :(

35. wasiqss

pirah heena hai wo ache sai samjha dai gi

36. pirah

pr wo online nhn h mje dopehar tak ye smjhna h

@wasiqss bhai, can u call heena ididi now ?plzzzzzzzzzzzzz. Unke liye pirah didi intezaar kar rahi hai.

38. wasiqss

mai kaise bolao bhai wo , dopahar ya sham tk ajae gi

Ooooooooooooo. Ab kya karen?

40. wasiqss

wait :P

41. pirah

ok m search krti hun

43. eashmore

No idea. Sorry.

45. arcticf0x

Here we go, http://en.wikipedia.org/wiki/Blood_type#ABO_blood_group_system I suggest you read that carefully and cross out. Post where you are stuck.

46. pirah

ok

47. pirah

in this link there is just explanation not my answer

48. arcticf0x

Yes, you must first understand how the system works and then solve your question yourself.

49. pirah

i want ti know about crossing

50. arcticf0x

Here we go then http://www.ncert.nic.in/NCERTS/textbook/textbook.htm?lebo1=5-16 Chapter 5

51. pirah

ok

52. Phascolarctos

53. pirah

no

54. Phascolarctos

Aadarsh, how can i help?

Ok did you understand the genotype of these blood groups?

56. pirah

yes

57. pirah

i want to know about crossing

58. pirah

how they crossed

59. arcticf0x

Have you done through that text? I suggest you go through section 5.2.

60. pirah

where is section 5.2?

Ok so for the first part Father is O grp & Mother is B grp case 1 . when Mother is Homozygus (both genes same) |dw:1334303625795:dw| O is recessive and can be expressed only in the homozygus condition so here B is dominant over O So children can have only B group

62. Phascolarctos

well, each parent gives one of the possible blood gropu alleles to the offspring. You know the possibilites are six: AA, AB, AO, BB, BO, OO. because there are three alleles in human populations. so one comes from mother and other from father and i saw the drawings of Aadarsh they seem correct. This is a typical example of polymorphism for the alleles or different versions of a locus or the same: a gene.

63. Phascolarctos

tell me if this helps a little, if not i try harder :-)

$I^o \text{can also be written as i}$

65. pirah

ok thnxx everyone
