• Sir can u plz inform us wen 2 watch biotechnology lectures, sir i have 2 prepare time table acc. 2 tht.. so in advance can u plz tell so tht i can take out time for those lectures and manage other subjects too?? plz reply sir.

• 3. codominace multiple allele

• no we not support because possible blood group B form

• 1)only AB
  2)A+, A-, AB+, AB-
  3)co dominance and multiple alleles
  4)The third child can be of blood group B if the genotypes of parents are I(A)I(o) and I(B)I(o)... so husband's claim is denied.

• 1= AB blood group.
  2=A blood group.
  3=codominance and multiple alleles.
  4= No, because blood group B is possible.

• Answer of today's homework
  1. AB blood group
  2. Father blood type is heterozygous condition I.e. Rh+/Rh- = A+/O- and mother blood type is also in heterozygous condition I.e. Rh+/Rh- = O+/O- in which when cross b/W father A+ with mother O+ then the child is A+ because the A is dominant over O, in other case when father O- is cross with mother O- the the child is a A- type
  3. Co-dominance and
  Multiple Allelism
  4. No. This condition not support the man's case because it's not possible to have a child of O blood group unless both the parent in heterozygous condition and according to ques. Man has O and AB blood group child by this when we made a cross b/W a male of IA,IO nd female IB,IO then all four blood type are possible because when male IA is cross with female IB THEN THE child is of AB blood group in other cross when male IA is cross with female IO then the child is of A blood group and when male IO is cross with female IB then the child is B blood group and in last when male IO and female IO is cross then the child is of O blood group .
  Thank you sir for everything you teach , motivate and inspire your single word makes a difference in life .. love u sir.
  I'm proud to be your commando..
  Ty Commander..

• Ans1= AB only
  Ans2= A- and AB-
  Ans3= co-dominance and multiple allesim
  Ans4= 3rd child may be B

• Menstruation occurs only if the released ovum is not fertilised, sir is this statement correct or wrong ?
  Sir my opinion is that this is wrong because the after fertilization if there is no process of implantation then also there will be menstruation

• 1-AB
  2-A-ve
  3-codominance & mutiplealleles
  4-man claims false bcoz if mother has I°Ià alleles & father has I°Ib alleles so possibility h b blood gp. ki
