beks73 [17]

Answer:

1) The alleles for homozygous brown hair will be BB.

2) The alleles for heterozygous brown hair will be Bb

3) Let's make a punnet square to check for the outcomes:

B   BB        Bb

B    BB       Bb

4) The results from the punnet square depict that the phenotype of all the children produced will be brown hair.

5) The punnet square depicts that there will be a 50% probability of the child to carry the heterozygous genome (Bb) and there is also 50% probability for the child to carry homozygous dominant genome (BB).

The nurse should first note the amount, color as well as the odor of the amniotic fluid.

For this case, there are minimal chances of cord prolapse because the fatal head is already engaged and at 0 station. If the fatal head is not yet engaged, the nurse should start by checking for cord prelapse if the membrane ruptures spontaneously. </span>
