Answer:
In this modern age of science. Which of the following shows the most promise in production crops with a higher yield
A genetic engineering of crops plants
If you are asking if that is true or false, it is false because all fungus like protists are heterotrophs, not autotrophs
Answer:
self polinate
Explanation:
Mendel is considered as the father of genetics and he was famous for his experiments on pea plant and on the basis of his experiment on pea plants he postulated the principles of inheritance which is called Mendel's law.
He used pea plant because pea plant can self pollinate, has bisexual flower, short life cycle, well discrete characters. So Mendel allowed the hybrid pea plant to self replicate so that the trait that is hidden can reappear in the second generation. So the right answer is self-pollination.
Answer: The correct answer for the given mechanisms influencing gene pool are the mechanisms of evolutionary change, which are described as follows-
1) Gene Flow
- It is described as the transfer of genes from one population to another population so that frequency of gene is increased.
-A zebra migrates to join a different herd of zebras.
2) Natural Selection
- A mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.
-Competition for sunlight leads to taller trees.
3) Mutation
- Permanent change in the nucleotide sequence of DNA ( genetic material) that could have harmful or useful consequences.
-The DNA of a snake changes to make its venom stronger.
4) Genetic Drift - It is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.
-A grassfire randomly sweeps through a population of buffalo and kills most of the animals.
Answer: given --> a pea plant with a yellow pea phenotype.
Explanation:
if its is round in shape then its a homozygous but if it is wrinkled in shape then its type is heterozygous.
To determine the genotype of this plant, we can use double gene cross method taking two possibilities - round and yellow or wrinkled and yellow.
its predicted phenotype can be 1:3:3:1.
