Answer:
D. LINE-promoted transposition.
Explanation:
Pseudogenes are traditionally defined as sequences that closely resemble known genes but do not produce a functional protein, which in many cases were actually genes, or copies of genes, degenerated by mutational processes that alter the reading frame of coding regions (ie that encode the amino acid sequence) or that interfered with the promoter elements that controlled their expression.
Pseudogenes originate by the same mechanisms as protein coding genes, followed by the subsequent accumulation of disabling mutations (e.g., insertions, nucleotide deletions, and / or substitutions) that disrupt the reading sequence in the coding regions, or lead to the insertion of a premature termination codon or the aforementioned reading frame change. However, it is believed that the transposition promoted by LINE is the main transposition responsible for the appearance of pseudogenes.
Answer:
The correct answer is - 50%
Explanation:
In the heterozygous condition, there is always one allele of dominant and one allele of recessive present together and during gamete formation, they assort independently. The probability of the pink flower that is RW can be found by punnet square:
R W
R RR RW
W RW WW
here, out of four two cases is of heterozygous or pink flower so the ration would be 2/4 or 1/2 or 50%
Answer:
Determine whether the trait has a dominant or recessive pattern of inheritance
Explanation:
This kind of information can be used to predict inheritance patterns in families. Depending on the genotypes, the dominant and recessive alleles and the different crosses, it can be deduced who are carriers of the disease and who express it. Similarly, by letting us know which chromosome (X or Y) is linked to the disease, we can know if the disease will be transmitted to the next generation depending on the genotypes of the parents.
The answer is C. The original population is the dotted line and the population after the selection is the faded blue. The two shell patterns are increasing while the most common was is decreasing.
Answer:
The given options are false regarding the question, the correct answer should be -
multicellular male gametophyte has a non-gamete cell that controls growth and development to the pollen tube and the male gamete.
The importance of these nongenetic cells of the male gametophyte is to control the development and growth of pollen tube that is an essential structure for pollination and fertilization.
