How do mutations effect individual traits?
Lostsunrise [7]
Mutations can affect the coding of "base pairs" in the chromosome of an individual by various means like:
1) by Deletion
2) by Duplication
3) by Translocation
4) by Inversion

After all that changes, codes deviates from normal information & can affect individual in negative way. In that manner, Mutations affect individual traits.

Hope this helps!

Which mutation is an example of an insertion mutation?
Burka [1]

Answer:

d. AAU CCG CAU UGG A​

Explanation:

A mutation is any change or alteration to the sequence of a gene. There are, however, different types of mutation depending on how it occurs in the gene. One of these types is INSERTION MUTATION as mentioned in this question. Insertion mutation is a type of mutation in which one or more nucleotide base is added to the sequence, hence, changing the reading frame of the original sequence.

In this question, the original mRNA sequence is given as: AAU CCG CAU GGA.

An insertion mutation will cause nucleotide base(s) to be added to this sequence, which will be noticed by an increase in number of bases in the sequence.

The correct answer is: AAU CCG CAU UGG A​. In this mutated sequence, nucleotide "U" has been added to the sequence.

The bones in the wings of birds and bats are _______ because they derived from a _______ ancestor, while the wings are _______ t
dolphi86 [110]
The answer is: homologous; common; homoplastic.

<span>The bones in the wings of birds and bats are <u>homologous</u> because they derived from a <u>common</u> ancestor, while the wings are <u>homoplastic</u> traits. Homologous structures are similar structures shared by different groups and that are derived from a common ancestor. The similar anatomy of bones in the wings of birds and bats is inherited from a common ancestor of tetrapods (to which birds and bats belong). However, wings are not inherited from the common ancestor of birds and bats. Therefore, wins are homoplastic traits (analogous structures) because they have similar function but they are not inherited from the common ancentor.</span>
