A TT genotype is said to be _____. homozygous heterozygous dihybrid
Goryan [66]
Homozygous.

You can tell in future that if both letters are either lowercase or upper case (e.g. TT or tt) the answer is always HOMOzygous. If the letters are different cases (e.g. Tt or tT) the answer is always HETROzygous. This is because 'homo' means 'same' and 'hetero' means 'different'.

Darwin thought that significant evolution was much too slow to be witnessed in a human lifetime. recent experiments by biologist
Ede4ka [16]

Significant evolution, in Darwin's opinion, moves much too slowly to be seen in a person's lifetime. Recent biological tests have demonstrated that some populations may develop extremely quickly, with significant changes happening over many generations in the lab.

What role does Darwin's theory of evolution play?

  • Charles Darwin, a scientist of the 19th century, investigated the idea of natural selection. Natural selection provides an explanation for how a species' genetic features might evolve through time. This might result in speciation, or the creation of a new, separate species.
  • The genesis and adaptations of species entered the scientific canon with Darwin's finding of natural selection. The adaptive characteristics of creatures might now be explained by natural processes, much as the occurrences of the inanimate universe, without the need for an Intelligent Designer.
