All living things are composed of cells. Some organisms, such as algae, are composed of a single cell (called unicellular organisms), while others, such as animals, are composed of many (called multicellular organisms). All living things grow and develop. ... Lastly, living organisms respond to their environment.
Pea plants have 2 different variations for their genes. Ex: All of the offspring get Y for yellow plant and y for the green plant so they are all Yy. Yy is a yellow plant. yy is a green plant because of gene variations
This mechanism allows killer T-cells to hunt down and destroy cells that are infected with germs or that have become cancerous.
The other main type of T-cells are called helper T-cells.
Helper T-cells orchestrate an immune response and play important roles in all arms of immunity.
Answer:
d. The tall and short traits assort independently of each other in this cross.
Explanation:
In the given example, the alleles for tallness and shortness of the plant belong to the same gene. The dominant allele “T” makes the plants tall while the recessive allele “t” is responsible for short plants. During gamete formation, independent assortment segregates the alleles of two different genes randomly. This process produces some new allele combinations in the progeny. However, the process of independent assortment is not about the segregation of alleles of a single gene from each other.
