Answer:
True
Explanation:
There are certain limitations associated with the Punnett Squares. They are not useful in case of complex genetic inheritance such as linkage between two genes. In case of linkages it becomes difficult to estimate the distribution of genotypes and phenotypes. For example in case of Nail-patella Syndrome and gene associated with blood group two genes lie on the same chromosome in close vicinity and hence there are high chances of inheritance of these traits in the offspring from the parent thereby causing random distribution of the two traits. This random distribution cannot be captured through punnet square.
The same problem is associated in case where a single gene is determined by multiple genes with graded effects of each gene.
Answer:
from the intermembrane space to the matrix
Explanation:
In the electron transport chain (ETC), electrons flow from one protein complex to another. However, as this electrons are transfered, protons (H+) is built up from the intermembrane space of the mitochondria to the mitochondrial matrix.
Hence, according to this question, a proton gradient is formed when hydrogen ions (H+) are moving from the intermembrane space to the matrix of the mitochondrial.
The correct choice is velocity=distance/time of v=d/t
Homologous chromosome pairs are separated
Meiosis 1 refers to the initial stage of meiosis where one parent cell divides into two daughter cells. This stage is where homologous pairs of chromosomes will segregate and separate from each other and move into the two daughter cells which result in the division of the total chromosomal number by half.
<h3>What happens during Meiosis 1 ?</h3>
Meiosis I ends when the chromosomes of each homologous pair arrive at opposing poles of the cell.
- The microtubules disintegrate, and a new nuclear membrane forms around each haploid set of chromosomes.
- The chromosomes uncoil, forming chromatin again, and cytokinesis occurs, forming two non-identical daughter cells.
