The mutation rate is the probability of a single gene mutating in an offspring bug.

Ilya [14]

Answer:

True

Explanation:

A mutation is any alteration in the genetic sequence of the genome of a particular organism. Mutations in the germline (i.e., gametes) can pass to the next generation, thereby these mutations can increase their frequency in the population if they are beneficial or 'adaptive' for the organism in the environment in which the organism lives (in this case, an insect/bug). The mutation rate can be defined as the probability of mutations in a single gene/locus/organism over time. Mutation rates are highly variable and they depend on the organism/cell that suffers the mutation (e.g., prokaryotic cells are more prone to suffer mutations compared to eukaryotic cells), type of mutations (e.g., point mutations, fragment deletions, etc), type of genetic sequence (e.g., mitochondrial DNA sequences are more prone to suffer mutations compared to nuclear DNA), type of cell (multicellular organisms), stage of development, etc. Thus, the mutation rate is the frequency by which a genetic sequence changes from the wild-type to a 'mutant' variant, which is often indicated as the number of mutations per round of replication, per gamete, per cell division, etc. In a single gene sequence, the mutation rate can be estimated as the number of de novo mutations per nucleotide per generation. For example, in humans, the mutation rate ranges from 10⁻⁴ to 10⁻⁶ per gene per generation.

Need it done as fast as you can it's do in 4 hours.

vagabundo [1.1K]

Answer no 1:

sW sW sw sw

Sw SsWw SsWw Ssww Ssww

sw ssWw ssWw ssww ssww

The genotype of the parents will be Ssww and ssWw.

About 4/16 offsrings will have the genotype SsWw, 4/16 will have the genotype Ssww. 4/16 will have the gentype ssWw. 4/16 will have the genotype ssww.

About 25% will have the phenotye, smooth and wooly. About 25% will have the phenotype smooth and non wooly. About 25% will have the phenotype non- smooth and wooly. About 25 % will have the phenotype non-smooth and non- wooly.

Answer No 2)

bT bT bT bT

Bt BbTt BbTt BbTt BbTt

The genotype of the parents will be BBtt and bbTT.

As seen in the punnet square, the phenotype of all the offsprings born from such a cross will be black trotter.

Answer No 3)

wd wd wd wd

WD WwDd WwDd WwDd WwDd

The genotype of the parents will be WWDD and wwdd.

The results of the punnet square illustrate that all of the offsprings will have white flower colour and disc shaped fruit.

Answer No 4)

The phenotypes of the rabbits will be as follows:

Ggbb - Gray hair and red eyes.

ggBB- White hair and black eyes

ggbb - White hair and red eyes.

GgBb - Gray hair and black eyes

Answer No 5)

Gb Gb Gb Gb

gB GgBb GgBb GgBb GgBb

gb Ggbb Ggbb Ggbb Ggbb

8 out of 16 offspring will have Gray fur and black eyes.

8 out of 16 will have gray fur and red eyes.

0 out of 16 will have white fur and black eyes.

0 out of 16 will have white fur and red eyes.
