Biodiversity supports biological system efficiency where every specie, regardless of how little, all have a vital part to play. For instance, A bigger number of plant species implies a more prominent assortment of products. More noteworthy species assorted variety guarantees common maintainability for all living things.
Answer: 25% are homozygous with the dominant gene (VV), 25% are homozygous with the recessive gene (vv), and 50% are heterozygous (Vv). Only the flies with vv will display the trait.
The correct answer is: C-MITOCHONDRIA
<span>Sunset, this is really similar to the question about molecular clocks you asked. The more closely related the three species are, the more similar the homologous proteins will be in each of the species.
Defining 'sequence similarity' is a little bit nuanced. It can refer either to the genetic code or the amino acid code. Because the genetic code is degenerate multiple codons code for the same amino acid - mutations in the gene don't result in mutations in the proteins when the mutated codon codes for the same amino acid as the unmutated codon.
Similarly, you can sort of think of some amino acids as being redundant. In some cases, replacement of one amino acid with another doesn't result in all that much change to the protein's structure or function. The result is, as species diverge and mutations build up, they build up preferentially in certain domains of the protein and more frequently involve replacement of one amino acid with one which is pretty much similar to it.</span>
a. that are all affected
Since the father is homozygous dominant (AA), and he is affected, that means that the disorder (or whatever it is), is autosomal dominant (plus it directly tells you that). That means it is not carried on the sex chromosomes. Since every child he has will inherit one of his alleles, they will all be affected by having at least the one.
