The independent assortment of genes during meiosis can result in a wide range of genetic combinations in offspring. The probability of the parent's aabb and aabb producing an aabb offspring is 100%.

Assuming that the parents, aabb and aabb, have dominant alleles (A) and recessive alleles (a) for a particular trait, the probability of producing an aabb offspring can be calculated using a Punnett square.

A Punnett square is a grid that shows the possible offspring combinations resulting from a cross between two parents. To construct a Punnett square for these parents, you would write one parent's alleles along the top and the other parent's alleles along the side. Then, fill in each box with the possible offspring combinations by combining the alleles from each parent.

In this case, the Punnett square would show four boxes, each containing the offspring combination "aabb." This means that the probability of producing an aabb offspring from this cross is 1 (or 100%). This is because each box in the Punnett square represents one possible offspring, and all four boxes contain the same combination.

It is possible to eliminate a particular allele, such as the red allele, from a population through a process known as selective breeding or artificial selection.

In selective breeding, individuals with the desired traits are selectively bred with each other to produce offspring with those traits, and individuals with undesirable traits are not bred. Over time, and with repeated selection, the frequency of the undesirable allele in the population can decrease and eventually be eliminated.

The exact number of generations it would take to completely eliminate the red allele depends on several factors, including the size of the population, the rate of mutation, the level of selection pressure, and the degree of inbreeding. These factors can greatly influence the speed at which the frequency of the red allele changes, and thus, the number of generations needed to eliminate it.

Without specific data on the population and the selection pressure being applied, it is not possible to estimate the exact number of generations needed to eliminate the red allele. Additionally, complete elimination of an allele may not always be possible or desirable, as genetic diversity is important for the adaptation and survival of populations.

To guarantee that the seeds produced by the four o'clock plants are pink-flowered, the plant nursery owner should practice selective breeding.

This involves carefully selecting and cross-pollinating only those plants that produce pink flowers and discarding those that produce other colors.

To begin, the plant nursery owner should identify the parent plants with the desired trait (pink flowers) and isolate them from other plants to prevent cross-pollination. Next, the owner can cross-pollinate the pink-flowered plants by manually transferring pollen from one plant to the stigma of another. This ensures that only pink-flowered plants are used in the next generation.

The resulting offspring should be evaluated to determine if they have inherited the desired trait. Only those that have pink flowers should be kept for future breeding. This process can be repeated over several generations to further enhance the prevalence of the desired trait (pink flowers) in the population.

Photosynthesis is the process of utilizing light energy to produce carbon compounds in cells.

Photosynthesis is the conversion of carbon dioxide and water into glucose/carbohydrates and oxygen in cells using light energy. Chlorophyll absorbs the reddest and blue light and reflects the greenest light. Plants absorb carbon dioxide (CO2) and water (H2O) from the air and soil during photosynthesis. Within the plant cell, water is oxidized, which means it loses electrons, whereas carbon dioxide is curtailed, which signifies it gains electrons. Water is converted to oxygen, and carbon dioxide is transformed into glucose.

Photosynthesis is the method by which plants and other organisms convert light energy into chemical energy, which is then released to fuel the organism's activities through cellular respiration.  Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are synthesised from carbon dioxide and water - hence the name photosynthesis, from the Greek Phós (φῶς), "light", and synthesis , "putting together".  Photosynthesis is performed by most plants, algae, and cyanobacteria; these organisms are known as photoautotrophs.

The Punnett square shows that the offspring of this cross will have a 50/50 chance of inheriting either the WW or Ww genotype, and a 50/50 chance of inheriting either the wW or ww genotype.

To determine the genotype of the parent fruit flies, we can create a Punnett square. Assuming that each parent contributes one allele to the offspring, a possible Punnett square for this cross is:

| W | w

--|----|--

w | WW | Ww

w | WW | Ww

The result of the cross shows that there are 793 offspring with normal wings (WW or Ww genotype) and 811 offspring with vestigial wings (wW or ww genotype). Since the normal wings are dominant, the only possible explanation for the appearance of vestigial wings is if at least one of the parents had the ww genotype.

Therefore, the genotype of the parent fruit flies is likely one normal-winged (WW) and one vestigial-winged (ww) individual. The Punnett square shows that the offspring of this cross will have a 50/50 chance of inheriting either the WW or Ww genotype, and a 50/50 chance of inheriting either the wW or ww genotype.

You have found a mammoth tusk buried in the tundra of the Arctic. Even though only 25% of the carbon-14 in this fossil is still present, it indicates that the animal was alive 11,460 years ago.

When a neutron interacts with a nitrogen atom, it captures the neutron and releases the proton, transforming nitrogen into the unstable isotope of carbon C-14 with fourteen nucleons (6 protons and 8 neutrons). As carbon-14 breaks down and turns back into nitrogen, beta particles are released.

With a nucleus made up of 6 protons and 8 neutrons, carbon-14, often known as 14C or radiocarbon, is a radioactive isotope of the element carbon. The radiocarbon dating technique was developed by Willard Libby and colleagues (1949) to date samples from anthropology, geology, and hydrogeology based on their presence in organic components.

5,730 years make up carbon-14's half-life.

In two half-lives, the amount of carbon-14 in a sample will drop to one-fourth (1/2 x 12 = 1/4). The animal must have been alive 2 x 5,730 = 11,460 years ago because the half-life of carbon-14 is 5,730 years.
