Answer:
- The blood group of the father must be B.
- The genotype of blood group would be
. - The Rh factor of the father can either be positive or negative.
- Thus, the genotype of Rh factor of father would be either Rr or rr.
Rh factor:
The phenotype of the mother Rh factor is positive. Thus, she can have Rr or RR as her genotype as positive is a dominant trait.
If the genotype of the mother is RR then all the offspring would be positive for Rh factor. However, one of the offspring is Rh negative, that means the mother must be heterozygous that is, Rr.
The genotype of the father can either be Rr or rr in order to produce offspring with positive as well as negative Rh.
Blood group:
The blood group of the mother is A. Thus, the genotype can either be
or
.
However, the blood groups of the children are O+ and B+.
Thus, the genotype of the mother must be heterozygous that is
.
The blood group of the father must be B with genotype
in order to produce offspring with blood group O and B.
Answer:
The correct answer is globular.
Explanation:
A huge group of old stars, which are packed closely in a symmetrical, somewhat in a spherical formation is known as a globular cluster. They are known as globular due to their roughly spherical look and are the most massive and the largest kinds of star clusters. The Milky Way galaxy comprises of approximately 150 globular clusters.
There is one primary root in a taproot system. The taproot system is where the primary root will become the main root and it will be branching roots. The other type of root is called Fibrous root system. The difference is that the taproot system is deep-rooted.
The difference is that it grow about 3 centimeters in 4 more days. Plus it grow faster than the other two plants.
