Answer:
B. misalignment of the chromosomes during anaphase I
Explanation:
Aneuploidy refers to an error in the chromosomal number of a cell. This occurs when the chromosomes fail to separate equally into individual cells, a process called MEIOTIC NONDISJUNCTION. Meiotic disjunction can occur in either the anaphase stage of meiosis I or meiosis II, however, different outcomes are produced.
When chromosomes fail to separate at meiosis I, it results in two gametes that lack that particular chromosome (n-1) and two gametes with two copies of the chromosome (n+1). This means that the four daughter cells will have an incorrect number of chromosomes, hence, the misalignment of the chromosomes during anaphase I will result in four aneuploid daughter cells.
The question is incomplete. The complete question is:
In pea plants, yellow pod color is recessive and green pod color is dominant. A heterozygous plant produced offspring with a plant that is homozygous dominant for the trait. What is a percent chance that the pea plant will have green pods.
Answer:
100%
Explanation:
Let's assume that the allele "G" gives green pod color while the allele "g" imparts yellow color to the pods. The genotype of the heterozygous plant would be "Gg". A cross between heterozygous green plant (Gg) with homozygous dominant (GG) plant would produce progeny in following ratio=
Gg x GG= 1/2 GG (green): 1/2 Gg (green)
Therefore, there are 100% chances that the progeny plant will have green pods.
Along with neuropsychological assessment, brain imaging and recording techniques may be used to shed light on relationships between brain function and underlying abnormalities.
Brain imaging is technique used to image the structure (tumor or injury) and function (metabolic diseases and lesions) of the central nervous system.
Answer:
C. 3:3
Explanation:
"Ozone is a gas that is naturally present in our atmosphere. Each ozone molecule contains three atoms of oxygen and is denoted chemically as O3. Ozone is found primarily in two regions of the atmosphere." https://csl.noaa.gov/assessments/ozone/2002/qandas1.pdf
