Organism X is an animal, and organism Y is not.
Organism Y has the benefit of not having to find a mate.
Organism X has offspring that are not genetically diverse.
Organism Y is a heterotroph, and organism X is not.

Genetic diversity is characterised by genetic diversity within a species. Recombination of genetic material during the inheritance process results in genetic diversity. It alters as space and time pass. Because it produces distinct offspring by fusing the DNA of the parents, sexual reproduction is crucial for sustaining genetic diversity.It happens as a result of gene recombination during the inheritance process.The genetic diversity varies over time and space.One of the most important components of genetic diversity is sexual reproduction, which uses a combination of parental genes to create unique children.Genetic variety is also a result of gene mutation, genetic drift, and gene flow.Individuals of the species can adapt to challenging environmental conditions thanks to genetic variety.The ability to adapt to unfavorable environmental conditions, illness resistance, and other physical qualities are given to the individuals.To know more about Genetic check the below link:

The question above isn't complete, as there are no options for us to choose from. That being said, the most common method for determining musical heritability is comparison.
Heritability is generally defined as a statistic that estimates the degree of variation in a trait in a population that is due to genetic variation between individuals in that population. To determine how heritable musical ability is, one can compare participants coming from musical families with participants coming from non-musical families.

The apoptotic pathway in human immune cells is signed:
the binding of many Fas molecules to receptors causes receptor clustering. → the intracellular regions of the receptors, when together, bind proteins called adaptor proteins → a death signal is received when a molecule called Fas binds its cell-surface receptor → these in turn bind to inactive molecules of caspase-8, which become activated and then activate caspase-3. → once activated, caspase-3 initiates apoptosis.How does the apoptotic pathway work?There are two main pathways to apoptosis which are extrinsic and intrinsic. It is mediated by proteolytic enzymes known as capsules that trigger the death of cells by splitting proteins specific to the cytoplasm and the nucleus.
The Fas binds to Fas receptors located in cell surfaces and recruits an adaptor protein, FADD that contains a death domain. The death effector from the domain recruits inactive caspase 8 that splits to generate an active caspase 8 that triggers inactive caspase 3 and activates it to split substrates within the cell and initiate apoptosis.
