breed animals with desired phenotypical traits/ no health issues together via natural selection but with human interception. example: if a dogs family has a dominant allele of being aggressive and all puppies within that litter and previous generations tend to be protective, they may be bred with a muscly dog to achieve a dog with the same dominant aggression allele but is also very strong for a guard-dog- can use a punnett square to theoretically predict % chance of puppies having the desired characteristic.
Answer:
C) They differ in their genotype and in their phenotype.
Explanation:
Genotype refers to the genetic composition of an organism. It represents the gene and the respective alleles present in the genome of an organism. The genetic traits exhibited by organism due to the presence of a particular gene in its genome reflects the associated phenotype. Phenotype is the morphological expression of genotype.
The ability to synthesize histidine is a genetic trait. Bacteria not able to do so lack one or more genes that code the proteins involved in histidine biosynthesis. Here, the inability of histidine biosynthesis is the phenotype governed by the absence of the respective gene. Therefore, the bacteria unable to form histidine have different genotype and phenotype from the ones that can synthesize it.
is that the full question?
Answer:
It can easily remove dirt.
Explanation:
When dirt is present on the hard surface such as car or machines so it can be cleaned by using hard cloth because the dirt attached tightly to the surface which can only be removed from that surface with the help of using hard cloth. Hard cloth has rough surface which easily remove the dirt from the surface as compared to the light cloth so that's why hard cloth is used to remove dirt from the surface.
The cortical reaction. It is initiated during fertilization by the release of cortical granules from the egg, which prevents multiple sperm with one egg.
