Answer:
b
Explanation:
the ratio should be the same so there should be four particles on the left and 2 on the right
Fertilization occurs in the fallopian tubes
The RYR1 gene is responsible for producing the protein ryanodine receptor 1. This protein transport calcium ions to the cells for muscle contraction. When this receptor remains open for a long time, you would expect an excess of calcium ions which would result to muscle rigidity. The excess calcium ions would also increase body temperature and produce excess acid.
<span>The birds with the longer beaks will be fittest in the environment post-drought because they will be able to gather resources (food) hence survive. This will enable these bords to reach reproductive again and pass down the genes. It is important to note that fitness in nature is determined by the capacity to reproduce.

<span>Natural selection will change the allelic frequency such that the allele for long neck will be more in the population while that of short beaks will reduce. This is because short beaks trait will not be able to reach reproductive age (due to starvation) because of the incapacity to gather food <span>resource hence their genes will keep reducing in the subsequent generations.

<span>Natural selection is a natural selective force that acts on a population and results to variation (differential) in the survival of the individuals in the population due to variations in phenotypes in the population. The most successful traits (phenotype that is best suited for the environment) are able to reach reproductive age, find a mate and reproduce hence leave its genes in subsequent generations</span>
Your answer is B.) Heterozygous, since the prefix 'hetero' usually means separate or different. Hope this helps.
