Based on the question above, the best answer would be:
That the headless horseman had to hold his head in his arms
is because he “wanted to see what’s ahead.”
Or a simple geometric equation of SOH CAH TOA would help
solve the angle degree.
Answer:
Punnett square is a square diagram which is used to predict the genotype of the offspring produced by particular cross.
Let P and p be the alleles of the gene responsible for the flower colors in a plant.
The genotype of both the parents is given as heterozygous that is, Pp.
Two types of gametes would be formed P and p.
The cross is shown in the image below.
The cross would be result in offspring with three types of genotypes PP, Pp and pp in 1:2:1.
Answer:
The population suffered a genetic bottleneck, which decreased genetic variation and thereby randomly increasing the frequency of harmful alleles
Explanation:
A population bottleneck, also known as genetic bottleneck, can be defined as a drastic reduction in the size of a population, which may be caused by anthropic activity and/or environmental phenomena (e.g., earthquakes, famines, fires, droughts, etc). A genetic bottleneck leads to a reduction in genetic variability within a population. Moreover, the genetic drifit caused by a genetic bottleneck can also increase the frequency of harmful alleles/mutations (it is due to the random sampling of individuals), thereby increasing the frequency of deleterious alleles/mutations in the population.
<h3>Question from alternative source</h3>
Many different types of mutations can occur within the body. Cystic fibrosis is a genetic disorder that is caused by different mutations within the CFTR gene. One mutation in the CFTR gene that leads to cystic fibrosis causes translation to end earlier in the gene sequence. Which type of mutation causes this translation error that leads to cystic fibrosis?
- silent
- missense
- nonsense
- deletion
Answer:
Nonsense
Explanation:
Nonsense mutations describe mutations that produce a premature stop codon. The stop codons are UAG, UAA, and UGA. A way in which this could arise is, for example, if there was a substution of a nucleotide in the mRNA codon UAC (which codes for the amino acid Tyrosine) to the nucleotide UAG (which codes for a stop codon).
The translation machinery would reach this codon, which signals that translation should be terminated. This would mean that the mRNA would be released, and a truncated (shortened) version of the amino acid would be produced. This is likely to be non-functional, and may even be marked for destruction by the cell.
The fusion of the sperm with the egg results in the formation of a zygote that develops into a new offspring. Twins refers to the two offspring which are a result of the same pregnancy. They are of two types. Monozygotic twins are a result of the single zygote (formed by the fusion of one egg with a single sperm) spiltting into two embryos forming the identical twins. Dizygotic twins are a result of two eggs fertilized with two different sperms forming the fraternal twins.
Identical twins are genetically simliar. The genetic material is derived from the same embryo and thus, the DNA of the identical twins are nearly identical. The spilitting of the embryo formed results in the separation of the same genetic material or identical DNA getting incorporated into the twins making them look alike in majority of the cases.
