Answer: If both the parents have blue eyes, there are 99% chances that the baby will have blue eyes.
Answer:
a) genetic drift - yes
b) Natural selection - yes
c) Gene flow - yes
d) Mutation - yes
Explanation:
factor that alter the allele frequencies are
a) genetic drift - yes
b) Natural selection - yes
c) Gene flow - yes
d) Mutation - yes
Genetic drift - Alter occur due to sampling error or selecting error. in this some error occur while deciding for the allele for the next generation.
Natural selection - it is due to large number of one type of allele in the population
Gene flow - it alter because of migration of allele among the populations.
Mutation - it is strong for introduction of new alleles in the population
According to the article I've read in the website of Harvard Health Publishing (Harvard Medical School), the causes of overweight or obesity have been implicated by more than 400 different genes. Genes provide overweight in so many ways like metabolism, appetite, cravings, distribution of fats, and stress eating. Although it depends on one person to another person. Researchers have said that 25% of predisposition to be overweight is accounted to genes, while 70%-80% for genetic influences. These are just some of the reason how much of your weight depends on your genes:
-For much of your life, you have been overweight
-Overweight is seen on your parents or relatives, your likelihood to be developing obesity is as high as 80% if both of your parents are overweight
