If purple is dominant, the genotype of the purple flower could be PP or Pp, as both would give a purple colour. However, if the crossed flower turned out to be white, we could say with certainty that the genotype of the purple flower is Pp as the genotype of the white crossed flower would be pp, which would not be possible if the purple flower's genotype was PP.
Answer:
Incomplete dominance
Co-dominance
Explanation:
Gregor Mendel discovered the principles that governs heredity, in which one of them is that an allele called DOMINANT allele, is capable of masking the expression of its variant allele called RECESSIVE allele in a heterozygous state. However, there has been genetic scenarios contrary to this his LAW OF DOMINANCE.
One of those Non-mendelian pattern of inheritance is a phenomenon called INCOMPLETE DOMINANCE, where an allele does not mask the expression of another completely, instead their combined state produces a third intermediate phenotype that is different from both parents. This is the case of the homozygous black bull mated with a homozygous white cow to produce a grey calf. The grey phenotype is an intermediate phenotype of both the black and white colours that forms due to incomplete dominance.
Another genetic scenario is called CO-DOMINANCE, where one allele is neither dominant nor recessive to the other allele, but instead both phenotypes becomes simultaneously expressed in the heterozygous offspring. In this case, the black bull and white cow were mated to form a heterozygous calf with both black and white spots.
Answer:
White owl is the symbol of wisdom. The snowy owl is the symbol of endurance. It represents big dreams along with the ability to achieve them. It is the sign of new beginnings and moving forward with all might.
Answer: Speciation
Speciation is biological process in which new species are formed from the existing species. This occurs when the members of the population gets separated from others by a geographical, behavioral or other barriers. Such separated organism develop traits with the course of evolution, which makes them reproductively isolated with the parent population. The speciation can be of two types:
1. Allopatric speciation: The separated population evolve into separate species due to a geographical isolation.
2. Sympatric speciation: The separated population evolve into separate species without any geographical isolation.
