How does meiosis introduce genetic variation into offspring?

2 answers:

7 0

Answer: Meiosis leads to increased genetic variation by reshuffling genes and creating random genes. The variation produced by meiosis accounts for differences in closely related individuals, such as members of the same family, as well as genetic differences in people within larger populations

Genetic variation is introduced as a result of the distinct crossing over of chromosomes in both phases of prophase. In the meiosis process, there can also be mutations in the s phase which are very unpredictable and can result in some very significant variations depending on where the coding is. by independent assoartment and 3 by mutations in s phase. Because of the way that meiosis is set up it allows for the offspring to be either very similar to the parents or can even be very different from these factors.

aksik [14]

Answer:

For sample A, A=17.7 %, T=17.7 %, G=32.30%, C=32.30%

For sample B, A= 28.9%, T=28.9%, G= 21.10%, C= 21.10%

Explanation:

The composition of nitrogenous bases in DNA is calculated using the suggestions proposed by the results of the experiment performed by Erwin Chargaff.

He found that in a DNA sample the composition of purine to pyrimidine is 1:1. This indicates that the amount of purine equals pyrimidine. This can be presented as purines + pyrimidines= 100. Also, adenine binds thymine and cytosine binds guanine.

In the given question,

For sample A

A= 17.7 %, Therefore, thymine will be = 17.7 %,

A+T= 35.40%

Now, G+C=100- 35.40%

G+C= 64.60%

content of G= 64.60/2= 32.30%

content of C= 32.30%

For sample B

T=28.9%, A will be= 28.9%

A+T= 57.80%

G+C=100-57.80%

G+C= 42.20%

Thus content of G will be= 42.20/2=21.10

content of C= 21.10%

Thus,

For sample A, A=17.7 %, T=17.7 %, G=32.30%, C=32.30%

For sample B, A= 28.9%, T=28.9%, G= 21.10%, C= 21.10%

The phylum for invertebrate animals with jointed legs is Arthropoda.

S_A_V [24]

The phylum Arthropoda contains a wide diversity of animals with hard exoskeletons and jointed appendages. Many familiar species belong to the phylum Arthropoda—insects, spiders, scorpions, centipedes, and millipedes on land; crabs, crayfish, shrimp, lobsters, and barnacles in water (Fig. 3.72).
