From the Hardy-Weinberg equilibrium, the genotype frequencies in the surviving population after this selection event is A = 0.25, and a = 0.75.
<h3>What is the Hardy-Weinberg equilibrium?</h3>
The Hardy-Weinberg equilibrium describe the equilibrium which exists between the alleles of a species of organism when no external forces are acting on the population.
In Hardy-Weinberg equilibrium, the sum of allele frequencies is 1.
The allele frequencies for A and a are each = 0.5: therefore, A + a = 1
When the chances of survival of A is 0.5 and a = 1
Frequency of A = 0.5 × 0.5 = 0.25
Then a = 1 - 0.25 = 0.75
Therefore, the genotype frequencies in the surviving population after this selection event is A = 0.25, and a = 0.75.

Answer:
3. simple dominant-recessive
Explanation:
The thumb gene also known as the hitchhiker's thumb or bendy thumb is detected by the phenotype of a person. The phenotype is responsible for the physical appearance of people. Dominant and recessive traits comprise of alleles that help in the composition of chromosomes.
Traits that manifest strongly are known as the dominant traits and they are responsible for the straight thumbs found in some individuals. The recessive alleles manifest themselves when the dominant traits are not expressed. This would thus give rise to the bended thumb.
No because abiotic factors like water and temperature aren't made of cells. Water is made of atoms and molecules. Temperature is just a measurement.

These are the organisms that are considered to be the single celled protists most closely related to animals because the characteristics that can be found in these organisms are the characteristics that were probably present in the animal's ancestor organism. </span>
