Answer:
True
Explanation:
The Modern Synthesis is also called the Neo-Darwinian theory as it explains the fusion of Mendelian genetics with Darwinian evolution into a singular theory of evolution. It is sometimes referred to as the Neo-Darwinian theory.
It refers to evolution as "changes in allele frequencies within populations," in order to explain the genetic basis of evolution. The random genetic drift, gene flow, mutation pressure, and natural selection are seen to cause changes in allele frequencies. Resulting in several differences that can be seen gradually over a particular period in time.
In the Modern Synthesis, mechanisms of evolution and not natural selection takes a major role and it explains the continuance of genetic variation going along with Gregor Mendel's particulate theory of inheritance, where the alleles of a gene remain as individual entities rather than merging.
The major key players of the Modern Synthesis are R. A. Fisher and Sewall Wright (worked on population genetics), Theodosius Dobzhansky (studied the fruitfly Drosophila), Ernst Mayr (models of how speciation occurs), George Gaylord Simpson (introduced paleontological observations into Modern Synthesis) and G. Ledyard Stebbins (added some principles as a result of his botanical studies).
A. do so on membranes called thylakoids.
1) B- brown; b- red hair
Having brown hair is a dominant trait while red hair is recessive.
If the parents had a red-haired child it means they were carriers of the red hair trait, so their genotype is
Bb
2)Getting their genotypes together would result in the possibilities that you see at the image below.
1/4 = 25% BB - brown
2/4 = 50% Bb brown but carrier
1/4 = 25% bb red hair
Answer: 25%
3) The genotype of the child, as i said before would be
bb. By having both alleles being recessive the child will show red-hair. If it was any other genotype( BB or Bb), the child would have brown hair, like their parents.
Answer:
definition: Biotic factors are the living components of an ecosystem.
example: animals, plants, trees, grass, bacteria, moss, or molds that you might find in an ecosystem.
