Explanation:
pThe probability of having an offspring with both the dominant phenotypes for both genes is equal to the product of the individual probabilities. This means, the probability of having a dominant phenotype for both traits would be
The product probability rule states P(A∩B) = P(A) x P(B). In the exposed example, the probability of having a dominant phenotype is 9/16.
What is the product probability rule?The product probability rule allows us to calculate the probability of occurrence of event A and event B at the same time.
It is about a joint probability of two or more events that might happen simultaneously, not excluding each other.
This rule is based on the dependence or independence of the events. If two events A and B are independent of each other, the occurrence of one of them does not affect the occurrence of the other one.
For independent events, the rule establishes that, given two different events A and B, the probability of occurrence of both together is
P(A∩B) = P(A) x P(B)
The probability of inheriting one of the alleles from each parent is 0.5 (beacause each parent has two alleles).
According to this, the probability of having a dominant phenotype for both traits depends on the paretal genotypes.
For instance, let us analyze the cross between two dihybrid individuals AaBb x AaBb.
Assuming the involved genes code for different traits and both are independent genes, for easier calculations, we can perform crosses that involve each of the genes separately -events-, and then multiply de results according to the genotype and phenotype we are interested in (A-B-)

How many chromosomes are present in the cell before the start of meiosis?.
Answer: 46
Explanation: 46 chromosomes are present in the cell before the start of meiosis.
The number of chromosomes that are present in the cell before the start of meiosis is 46. Because the total number of chromosomes in a human cell is 46.
What are chromosomes?Chromosomes are the thread-like structure present in pairs in all organisms. They are present inside the nucleus, and contain genes and DNA in them, and are responsible for the traits of an organism.
Meiosis is a process completed in two stages, and each contains four phases. It occurs in the germ cells, divides the cell into four cells, and reduces the number of chromosomes.
The number of chromosomes in humans is 46, 23 in pairs. Before meiosis, the number of chromosomes will be 46 after Meiosis the number reduces.
Thus, there are 46 chromosomes in the cell prior to the onset of meiosis.

Explanation:
Hope this helps!!!:)
1. Introduction – this is where you explain to your audience why you are making this presentation/video/booklet. You will explain what it contains, as you would for an English essay, etc.
2. Explain coastal processes – erosion, transportation, deposition.
3. Explain two landforms – one erosion, one deposition – how they are formed and include an example(s) of where you can find this feature.
4. Explain the relationship between humans and the coast – how we benefit from the coast and how we can damage the coastline, and visa versa (e.g., coastal erosion, longshore drift that changes the shape)
5. Explain coastal management strategies and include a case study (an example) of a location where coastal management strategies have been put in place
6. Conclusion – as you would for your English essays.
Answer:
1.The processes of erosion, transportation and deposition occur as a result of differing wave and current energy,Where marine energy is high, disintegration, expulsion and transportation is bound to occur.
2.Erosion refers to the breaking down of the land by the force of waves. Transportation is the work of waves and tides in transferring this broken material somewhere else and deposition refers to the process by which waves and tides lose energy, cease to transport and release eroded material.
3.Erosional landforms include V-shaped valleys, interlocking spurs, waterfalls and gorges. Meanders and oxbow lakes are formed from erosion and deposition. Depositional landforms include floodplains.
4.The ‘blue economy’—a term that has emerged in the past decade—attempts to embrace the opportunities associated with the ocean, whilst recognising, accounting for and addressing the threats posed by such an economy. It is essentially the ocean equivalent of the ‘green economy’—a vision for a decarbonised, regenerative and more equitable economic system.
The ‘blue economy’ gained prominence at the 2012 UN Convention on Sustainable Development (UNCSD), or Rio+20 conference, when small island developing states began emphasising the importance of the ocean and marine economy in response to land-focused calls for a ‘green economy’
5.Coastlines are being eroded by waves and the weather.
Coastlines need to be managed because they are often used by humans for purposes such as housing.
To protect the coast from erosion, we can use hard engineering strategies (building man-made structures such as sea walls) and soft engineering strategies (using natural processes such as beach nourishment).
6.A conclusion is, in some ways, like your introduction. You restate your thesis and summarize your main points of evidence for the reader. You can usually do this in one paragraph. In the following example, the thesis statement is in bold. Notice that it is written in 2 sentences.

explain how natural selecin oacting on allele frequencies of a gene that controls body coloraiton can result in populations of 3 different species
Answer:
Answer below
Explanation:
Well when natural selection occurs, genes that don't benefit the speicies, or more accurately, harm it by ruining camoflague. Natural selection can result in one creature evolving into 3 different species when those creatures get put into different environments that promote genetic mutations that help them survive. After a long while of genetic mutations coming and going to adapt to their environment, those three members of the species are no longer the same species because they've all adapted to different environments.

What is shear stress?The force that causes deformation of a material by slippage along planes that are parallel to the imposed stress.
The resultant shear is very important in nature as it relates the down-slope movement of Earth material and to earthquake.
Shear stress occurs when a rock mass is pushed in parallel but in opposite direction.

Explanation:
Why do animals such as sparrows and deer experience less loss of genetic diversity due to fragmentation than for instance mice or salamanders
Answer:
Severe fragmentation is a typical fate of native remnant habitats in cities, and urban wildlife with limited dispersal ability are predicted to lose genetic variation in isolated urban patches. However, little information exists on the characteristics of urban green spaces required to conserve genetic variation. In this study, we examine whether isolation in New York City (NYC) parks results in genetic bottlenecks in white-footed mice (Peromyscus leucopus), and test the hypotheses that park size and time since isolation are associated with genetic variability using nonlinear regression and information-theoretic model selection. White-footed mice have previously been documented to exhibit male-biased dispersal, which may create disparities in genetic variation between males and females in urban parks. We use genotypes of 18 neutral microsatellite data and four different statistical tests to assess this prediction.
