Which type of point mutation will not result in frame shift occurring

Biology
1 answer:
Dominik [7]3 years ago
5 0

Answer:

Deletion mutation

Explanation:

it occurs when a base pair is deleted from a sequence.it is the opposite of insertion mutation.These two types of point mutation are grouped together because both of them can drastically affect the sequence of amino produced. With one or two based added or deleted, all of the three - base condom change . <u>This is called a frame shift</u><u>.</u> e.g if a sequence of condoms in DNA is normally CCT ATG TTT and an extra A is added between the two cytosine bases, the sequence will instead react CAC TAT GTT T. This completely changed the amino acids that would be produced, which in turn changes the structure and function of the resulting protein and can render it useless. Similarly, if one base was deleted, the sequence would also shift.

Attached earlobes are recessive to free earlobes. What genotypic ratio is expected when an individual with attached earlobes mat
Marianna [84]

Answer:

C

Explanation:

This is a monohybrid cross between involving a gene coding for earlobe. The allele for free earlobe (F) is dominant over that of attached earlobe (f).

N.B: let F represent the gene involved.

A genotypic ratio is the ratio derived from the offsprings based on the actual genetic make-up and not based on their phenotypic appearance as in phenotypic ratio.

A homozygous individual is an individual having the same kind of alleles for a gene while a heterozygous individual is one that has two different alleles i.e. combination of the dominant and recessive allele.

The monohybrid cross is between an individual with attached earlobe (ff) i.e. homozygous recessive individual. (Note that, a recessive trait will only be expressed in a homozygous state) and a heterozygous free earlobeb individual (Ff). (See attached picture). Ff × ff

The resulting four offsprings will

be expected to have only two distinct genotypes i.e heterozygous (Ff) and homozygous recessive (ff) in an equal ratio i.e. 2:2 ~ 1:1
