<u>Answer</u>:
According to the principal of dominance, if a recessive gene for tallness is paired with another recessive gene for tallness, the organism will be tall.
<u>Explanation</u>:
According to the law of dominance, parent having contrasting characteristic and is a true breeder, will be allowed to breed. The trait is dominant, which will be seen in the next generation. Dominant trait masks the expression of the recessive trait. Recessive trait will only appear only when the genotype will be 'homozygous recessive'. In this case recessive gene for tallness will be paired with another recessive gene, this will result in homozygous recessive genotype.
The answer is the Law of segregation.
This asserts that the two alleles for a gene unconnected throughout gamete development, and end up in dissimilar gametes. In the case of the heterozygous green-pod plant (Gg), one gamete will obtain the dominant allele (G), and the other gamete will obtain the recessive allele (g). The law of segregation explains for the prediction that 50% of the offspring of the test cross will have green pods and 50% will have yellow pods.
The option that supports evolution is all of these. Fossil records, molecular biology, and comparative embryology are all methods to confirm the existence of evolution through time. Fossils tell us how some ancient organisms have evolved to become some other organisms that exist today. Molecular biology studies molecules and how they changed through time. Comparative embryology deals with the studies of various embryos in order to see how they evolved.
