A is prophase
B is prometaphase
C is metaphase
D is anaphase
Answer:
A) 1:2:1
Explanation:
Incomplete dominance is an effect observed in the organisms in which the neither of the two alleles controlling a trait is dominant or recessive instead produces a phenotype formed by the mixture of the effect of the two alleles. Therefore in incomplete dominance, a new trait is produced which is formed by both the alleles.
In the given question, if incomplete dominance is observed in a monohybrid cross which results in two homozygous genotypes and two heterozygous genotypes. In F2 the phenotypic generation produced will be 1:2:1 as the heterozygous genotype will form a new phenotype.
Thus, Option-A is the correct answer
Answer:
This similarity indicates that mice share a common ancestor with humans. Mice have a tail, while humans have a tailbone
Answer: The correct answer for the fill in the blank is B) Advantageous traits become more common in a population.
Theory of natural selection was given by Darwin. This is one of the mechanisms of evolution.
According to this theory, organisms that are better adapted to their environmental conditions survive and increase their population by reproduction. So they pass the advantageous trait to the next generation. In other words, it reflects the survival of the fittest.
Due to this, the advantageous trait becomes more common in the population.
Thus, the correct option is B)
