Answer:
The answer is below
Explanation:
The possible phenotypes of the mother can be any of the following
AA - A phenotype
AB - AB phenotype (here the mother must have contributed an A gene for it to be possible)
AO - A phenotype (here the mother may have contributed any of the A or O gene.)
BO - B phenotype (here, the mother would only need to contribute O gene for this to be possible)
Answer:
<em>D) lining up of chromosomes in the cell</em>
Explanation:
Prophase can be described as the first stage of cell division. During this phase, The chromatin material condenses and becomes compact so that the chromosomes become visible. The nuclear envelope disintegrates and the nucleolus disappears. Hence, the choices mentioned in option A, B and C occur by the end of prophase.
Metaphase is the third phase of cell division. During this phase, the chromosomes line themselves in the centre of the cell. Hence, the lining of the chromosome does not occur by the end of prophase. This occurs during the third stage.
Answer:
C. BbSs
Explanation:
The foiled results of the genotype include both capital and lowercase versions of both letters, b and s.
This means the genotype has to be heterozygous for both the B and S traits, since the foiled results have both dominant and recessive alleles.
So, the genotype must be C, BbSs
