<span>Mutations sometimes improve the chances of survival for an animal.
But rather rarely. Advantageous mutations do happen, but neutral and harmful mutations are way more common.

Answer:
The combinations of gametes that could be produced from heterozygous individuals for both traits are PT, Pt, pT and pt.
Explanation:
An individual is heterozygous for two traits, flower color and stem height, with a PpTt (dihybrid) genotype and a phenotype showing the dominant traits, purple flowers and tall stem.
The genes of this individual for the above-mentioned traits contain different alleles, and taking into account the independent segregation of characters, the alleles present in its gametes could be:
- <em>Both dominant alleles: PT
</em>
- <em>One dominant and one recessive allele Pt or pT
</em>
- <em>Both recessive alleles: pt
</em>
Therefore, the traits of its offspring will depend on the alleles for those traits present in the gamete to which they are combined.
 
        
             
        
        
        
<h2>Evolution of phylogenies </h2>
Explanation:
- The genome of the endosymbiont is all the more firmly identified with individuals from the gathering in which it initially developed, while the nuclear genome of the inundating living being has its own evolutionary trajectory.  
- The accumulation of various inheritable attributes after some time which prompted the arrangement of another species  
- Nuclear and organellar genes advanced at various rates, clouding developmental connections.  
- Some mitochondrial genomes have been decreased definitely in size, losing a large number of the protein genes encoded in creature mtDNA just as a few or all mtDNA-encoded tRNA genes. 
- At ∼6 kb in size, the mitochondrial genome of Plasmodium falciparum (human intestinal sickness parasite) and related apicomplexans is the littlest known, harboring just three protein genes, profoundly divided and improved little subunit (SSU) and enormous subunit (LSU) rRNA genes, and no tRNA genes.
-  In stamped differentiate, inside land plants, mtDNA has extended generously in size (>200 kb) if not in coding limit, with the biggest known mitochondrial genome right now.
 
        
        
        
Answer:
15 percent
Explanation:
Lymphatic vessels recover about  15 percent of the fluid filtered by capillaries. In addition, these vessels contain white blood cells that fight infections.
