Answer:
Option B. mutualism
Explanation: Mutualism is a symbiotic association in which both the organisms gets benefits from one another. Bees helps in the pollination by transferring pollen grains from one plant to another and in return the flowers provide food in the form of nectar to the bees and in this way both the organism gets benefited. So the relationship which is present between flower and bees
is Mutualism.
C) egg and sperm
D) diploid body cells
Answer:
1. Incomplete dominance has occurred
2. A phenotypic ratio 1 Blue : 2 pale blue : 1 white will be obtained.
Explanation:
Mendelian principle states that one allele is capable of masking the expression of another i.e. one allele is dominant and the other one is recessive. Genetic scenarios that have gone against this principle has been observed. One of them is the concept of INCOMPLETE DOMINANCE, which is a case where one allele is not completely dominant over the other, hence, they combine to form a third intermediate phenotype different from both parents.
This is the case in the question where the the blue allele (B) fails to completely dominate the white allele (W), instead it forms an heterozygous plant (BW) with a different phenotype (pale blue) that is a blending of the two parental phenotypes (blue and white). This heterozygote (BW) is formed in the F1 generation.
If the F1 offsprings (BW) are self-crossed, four possible offsprings will be produced using a punnet square. This offsprings will have genotypes: BB, BW, BW, and WW. This depicts a genotypic and phenotypic ratio of 1:2:1 i.e. 1 blue (BB) : 2 pale blue (BW) : 1 white (WW).
Answer: Endangered species are species whose populations are dwindling in numbers and are in danger of becoming extinct. Extinct species are ones who have no documented individuals left and are therefore believed to no longer exist.
