Answer:
The Laura tried to grow micro-organisms in culture broth medium in Petri-plates but the microbial growth was not observed even on the fourth day of culture which could be due to:
1. Laura could have not provided the correct broth medium maintaining the with pH and salt concentrations.
2. Microorganisms did not get optimal growth conditions.
3. The bacterial source could have died after the collection which could have lysed after their death and thus no longer visible.
Answer:
roan coat color in horses
Explanation:
Codominance is one of the Non-mendelian inheritance patterns in genetics i.e. does not follow Mendel's principles of inheritance. Codominance is a phenomenon whereby an allele is neither dominant nor recessive to another in a gene i.e. one allele is not phenotypically expressed over the other. Hence, both alleles are simultaneously expressed in their heterozygous state.
An example of codominance is the roan coat color in horses where the colored (B) and white (W) alleles are both dominant in the coat color gene, hence, the horse expresses both black and white coat phenotypes known as ROAN (BW). The black and white alleles are said to be CODOMINANT.
Alleles in the F1 must be Tt to have height variety in the F2.
