ALL mutations have an effect on the protein. <br> A. True<br><br> B. False

KengaRu [80]

Answer:

B. False

Explanation:

No; only a small percentage of variants cause genetic disorders—most have no impact on health or development. For example, some variants alter a gene's DNA sequence but do not change the function of the protein made from the gene.

Free earlobes are dominant over attached earlobes. What is the probability that a woman with attached earlobes (homozygous reces

AVprozaik [17]

<h2>The correct answer is explained below:</h2>

Explanation:

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 = $\frac{1}{2}$ .
