Answer:
In humans, blood group is determined by three alleles
,
, and
.
and
are co-dominant whereas
is recessive to other two.
Thus, if a person with blood group O produces offspring with blood group B then the other parent must contain
allele.
The genotype of other person can be
,
, or
.
There is only one condition in which the person can have offspring with blood group O that is, when the other parent is
.
In this condition, the probability of an offspring to have blood group O is 50%.
In other conditions, the probability of an offspring to have blood O is 0%.
It all depends on the species, some lose all of their leaves for part of the year while others lose their leaves before the next growing season, retaining some during winter or dry periods.
