1.) Achodroplasia is a autosomal dominant disorder, the suspected case suggested that inorder for the parents to produce and offspring with achondroplasia. One parents must have a single mutant gene of achodroplasia to be inherited by his offspring. for this case, It is suggested that the offspring might have developed its own mutant gene as it only affect 1 in 25,000 birth. There is changes of genes during early development.
2.) The mother said that they don't have that history of disorder. again, it's autosomal dominant disorder. one parents must have that kind of disorder so their child can also inherit it. Thus, no of the childs parents is a carrier.
Answer:
Decomposers
Explanation:
Decomposers eat decaying or dead organisms to produce the nutrients.
Well, pollution is probably the main reason, but i think all of them are reasons why animals are dying off, if there isn't any choice for all of them, then your best bet would be to do a, pollution.
If there are 100 individuals in a population and 20 are homozygous for b, 60 are heterozygous, and 20 are homozygous for b, the allele frequency of b is 50%.
Allele frequency, sometimes referred to as gene frequency, is the percentage or fractional frequency of an allele (gene variant) at a certain location in a population. What is being discussed is the proportion of chromosomes in the population that carry that allele in comparison to the entire population or sample size. The slow change in allele frequencies within a population is known as microevolution.
Taking into consideration:
1. A particular allele at a particular chromosomal region.
2. A collection of N individuals with ploidy n, which denotes that each individual's somatic cells have n copies of each chromosome (e.g. two chromosomes in the cells of diploid species).
If an allele is found in a population on I chromosomes, the allele frequency is the proportion of all I occurrences of that allele to the total number of copies of the chromosome in the population (nN). Despite being related, the genotype frequency and the allele frequency are separate and one can infer the other from the other.

A volcano is a conical hill or mountain that ejects hot ash and lava in an eruption. In addition to hot ash a lava volcanoes erupt many gases. The most common gases erupted by a volcano are carbon dioxide, sulfur oxides and water vapor. Carbon dioxide is common in volcanic eruptions as it is formed mainly when subducting plates laden with the calcium carbonate skeletons of tiny marine organisms. Once the plate melts the carbon dioxide is incorporated into magma.
