According to the question, free ear lobes are dominant over attached ear lobes.
Let the allele for free ear lobes be represented by F.
Let the allele for attached ear lobes be represented by f.
The genotype of the homozygous recessive woman (mother) having attached ear lobes is : ff.
The gamete produced by the woman is: f.
The genotype of the heterozygous man (father) with free earlobes is: Ff.
The gametes produced by the man are: F and f.
Mating the man with the woman we get the following offspring,

F f

f Ff ff

Phenotype Free ear lobe Attached ear lobe

The genotype and the phenotype of the probable children obtained is represented in the Punnett square above.
The probability that the parents would produce children with attached ear lobes is = $\frac{1}{2}$ .

Topic: Blood Sugar

Alja [10]

Answer: Blood sugar/blood glucose levels are controlled by negative feedback involving the hormones human insulin and glucagon.

Explanation:

Insulin is produced in the increased , if there is too little glucose in the blood the pancreas is triggered and released more insulin to change glucagon into glucose, this regulates the amount of glucose in the blood. However if there is too much glucose in the blood (after a sugary meal) the pancreas is triggered to use insulin to lower the blood glucose levels, this is called negative feedback. This works by storing glucose as glucagon in the blood, insulin can be objected into the blood stream if a person needs it straight away(eg type 1 diabetes.)
