Detection of touching a hot object occurs through specialized tips of nerve cells called receptors. These receptors, located in sense organs, initiate a chemical reaction at the dendritic tip of a nerve cell in response to environmental stimuli.
If progeny inherited a single whole gene set from each parent, the characteristics, such as ‘R’ and ‘y’, would be linked to each other and could not be independently inherited. This linkage would prevent the segregation and recombination of different ...
Germ cells undergo a process called meiosis, where they divide to produce cells with only one set of genes. This reduction in genetic material is essential for sexual reproduction, ensuring that the progeny receive a combination of genes from both ...
Germ cells are responsible for producing reproductive cells, such as eggs and sperm, each carrying only one set of genes. This ensures that the progeny inherit a combination of genes from both parents.
