Question
5. A female heterozygous for type A (AO) blood After mitosis, a cell with 100 chromosomes at G1, mates with a male who is heterozygous for will form how daughter cells, with type B(BO) blood. What are the possible blood types of their offspring? a. A and B b. A, B and AB C. A,B, and O d. A, B, AB, and O e. None of these are correct with,_-_chromosomes in each one. A. 4,50 B. 2, 50 C. 2,100 D. 4, 25 2. After meiosis, a cell with 80 chromosomes at 01, will form??daughter cells, with with chromosomes in each one. A. 2,80 B. 4,80 ?.4,40 D. 4, 20 E. 2, 40 2. A female with type O blood has a child with type O bloed, she claims that a man with type AB blood is the biological father of the child. Can he be the biological father? a. Yes b. No 2. A female heterozygous of type A blood has a child with type O blood, she claims that a man with type B blood is the biological father of the child. Can he be the biological father? A. Yes 1. Which of the following would abways result in the beterozygous genotype? a. Ss x Ss b.Ss x ss e. SSsS B. No e. None of these.Explanation / Answer
5) when a cross takes place between AO X BO, the progeny can be AO,AB, BO and OO. Hence the offspring can have all the four bllod groups i.e A (AO), B (BO) AB (AB) and O (OO). So the correct answer is D.
Mitosis forms two identical daughter cells with same number of chromosomes as the parent cell So the coorect answer here is (c) that is After mitosis a cell with 100 chromosomes at G1 will form 2 daughter cells with 100 chromosomes in each one.
Meiosis forms 4 cells with half the number of chromosomes as the parent cell. So here the numcer of cells formed after meiosis will be 4 with 40 chromosomes in each cell. So the correct option is (c)
No, A man with blood group AB cant be the biological father of a child with blood group O and mother with blood group O.
Yes, a man with blood group B can be the biological father of a child with blood group O and mother with blood group type A heterozygous.
