The nucleus manages the daily operations of the cell. Organelles need instructions from the nucleus. Without a nucleus, the cell cannot get what it needs to survive and thrive. A cell without DNA lacks the capacity to do much of anything other than its one given task.
Answer:
iAiA and iBiB
Explanation:
Blood type in humans is controlled by a gene with three alleles namely: iA, iB, and i. Alleles iA and iB are dominant over allele 'i' but codominant. The following are the allelic combinations of the genotype and the resulting blood types:
iAiA or iAi - type A
iBiB or iBi - type B
iAiB - type AB
ii - type O
According to this question, one parent has type A blood and the other has type B. If all the offsprings of these parents have blood type AB, this means that the parents must have a genotype of iAiA and iBiB respectively.
The answer would be Organelle.
Answer:
Reciprocal cross may be defined as the cross done by reversing the parent genotype. The reciprocal cross was performed by Mendel's during the pea plant experiment.
Mendel's reciprocal cross is important as it determines the contribution of the male or female in the particular trait. He reversed the male and female trait, cross them, whether the male or female is responsible for the transmission of the trait. He found that the progeny of the reciprocal cross are similar as the normal cross. Thus, he concluded that both the parents contribute equally in the transmission of trait.
