Answer:
The frequencies would be - AaBb= 2/4= 1/2.... Therefore AaBb= 50%
- aabb= 2/4= 1/2.... Therefore aabb= 50%
Explanation:
The resulting F1 cross, AaBb, indicated that A is dominant over a, and B is dominant over b. Therefore a cross between AaBb and aabb would result to---
AaBb x aabb
= AaBb AaBb aabb aabb
Answer:
Explanation:
Biogeochemical cycles represent the main system by which the energy of the Sun is transformed into energy of the chemical compounds by living beings and products of their activity. :)
It is very true that masculinity and femininity are very strongly dependent on the society in which these terms are used. While there are genetic differences underlying the phenotype of being more masculine (having a bigger jaw, more hair on the body), there are also a lot of societal factors determining what is considered to be masculine and what feminine in a society.
Answer: Sexual reproduction is advantageous over asexual reproduction because it reduces the rate of mutation accumulation.
New Zealand mud snails reproduce through asexual and sexual modes of reproduction. Asexual reproduction allows these organisms to reproduce more number of offsprings. Asexual reproduction advantageous as these organisms faces natural disaster conditions like tide, drought results in the decrease in the population. Therefore, does not get mate to undergo sexual reproduction. Sexual reproduction in these snails results in genetic variation in offsprings. Sexual reproduction results in increase in mutation rate in the genetic material being passed to offsprings because of resorting of genetic material being distributed from parent to offspring. This will result in genetic variations. Hence, parent will be different from offsprings. In asexual reproduction offsprings are the clones of parents as there is no resorting of genetic material takes place.
