Question

Normal genes that promote cell division are called In a 2-point testcross, the offspring are 250 parental and 300 nonparental (recombinant). Are the genes linked? Intercalating agents are mutagens that cause mutations A fertile hybrid of broccoli (n = 9) and turnip (n = 10) could have or chromosomes is the only human autosomal trisomy in which the individuals may survive to adulthood. The DNA sequencing gel on the screen reads Crossovers in an inverted chromosome region can cause mutations, which lead to miscarriages causes thymine dimers, which can be repaired by

Explanation / Answer

1). Human blood group is determined by multiple allele system, in which IA and IB are co-dominant to each other and dominant over IO.

Cross between heterozygous man with the blood group A (IA I) and the women with the blood type B (IB I) will have the progeny with the following genotypes and phenotypes.

IA I * IB I ---> IAIB (1/4, blood type AB), IA I (1/4, blood type A), IB I (1/4, blood type B), II (1/4, blood type O).
