Answer: option A
Explanation: As demonstrated by the Hardy-Weinberg principle, the dominance or recessiveness of an allele does not determine its frequency in a population.
The correct answer is metaphase 11. The chromosomes line up at the equator
Answer:
C. 1/4
Explanation:
Let's assume that the allele for the spotted coat is "S" and the one for the even coat is "s". The allele "L" gives short horns while the recessive allele "l" imparts long horns. The genotype of the cattle heterozygous for both traits would be SsLl. A cross between two heterozygous cattle would produce progeny in following phenotype ratio=
9 spotted coat and short horns: 3 even coat and short horns: 3 spotted coat and long horns: 1 even coat and long horns.
Therefore, the proportion of the progeny with long horns = 4/16= 1/4
Answer:
Option A is the correct answer. To conduct a controlled experiment would be the best choice for Maria to test her prediction.
Explanation:
A controlled experiment can be described as an test in which one of the test models is kept constant for a variable, while in other experimental models, a change is made for testing the variable.
It would be best for Maria to conduct a controlled experiment. In the control model, Maria should keep light as constant whereas in other experimental models she should increase and decrease the quality of light to test her prediction. She should then compare her experimental results with the control model to deduce the results.

Binary fission is a reproduction process wherein one cell divides asexually into two cells forming two daughter cells. into In binary fission, the chromosome is being replicated in which the resultant prokaryote is exactly the same copy of the parental prokaryote which means to say that there is no chance for genetic diversity. However, prokaryotes can still share or even exchange genes through the mechanisms of transformation, transduction and conjugation.</span>
