I) Alleles is the alternative form of a gene or in other terms the variant form of a gene. If there are two alleles at a locus p and q are used to represent their frequencies. Frequencies of all alleles in a population will add up to 1.
Therefore, in this case if red allele CW is p=0.7, then the frequency of the white allele in this population (q) is 0.3.
ii) From the punnet square the expected genotypes frequencies in the offspring generation will be 0.49 CRCR (red flowers, o.42 CRCW (pink flowers) and 0.09 CWCW (white flowers).
I pretty sure I answered this and it was B please tell me if I’m wrong
Answer:
the answer is bts zqt z=5
Explanation:
It permits calcium to leave the sarcoplasmic reticulum and enter the cytosol. During muscle contraction, the binding of acetylcholine initiates an excitatory impulse, which is transmitted to the deep of the muscle via T tubules. T tubules are the invaginations of cell membranes of muscle cells (sarcolemma). When the action potential travel down the t-tubules, they change shape and allow the calcium ions to enter into the sarcoplasm from the sarcoplasmic reticulum.
