move separate directions during anaphase of mitosis are conn

move separate directions during anaphase of mitosis are connected together in metaphase of mitosis move close together during prophase I of meiosis all of the above A difference between oogenesis and spermatogenesis is that only oogenesis a) uses meiosis b) produces one diploid gamete c) begins with a diploid cell d) occurs in less than one day e) unequal cytokinesis Bob has blood type A and his wife, Carol, has blood type AB. They made a son, Arthur. Which of the following could not be Arthur\'s blood type? type O type B type A type AB all of the above are possible

Solution

12.A difference between oogenesis and spermatogenesis is that only oogenesis:- e)has unequal cytokinesis

All other fuctions that given in other options are common in Spermatogenesis and oogenesis.

13.a)type O

because the father contains A allele in his blood whereas mother contains both A allele and B allele in her blood.

The child produced will either have A Blood type as it A allele present in both the father and mother blood,Either only B blood type as mother has B allele or AB blood type as the mother has the blood type.There is no chance of having O in the blood type.
