Which claim below accurately explains how the process of meiosis results in genetic variation?

Biology
1 answer:
MatroZZZ [7]3 years ago
5 0
Below are the options:

Having two phases of meiosis allow for more unique cells to be produced.


Meiosis is a form of asexual reproduction which leads to more genetic variation.


Meiosis produces 4 haploid daughter cells which all contain identical DNA segments.


<span>Crossing over during metaphase allows segments of DNA from 2 parents to SWAP and produce non-identical haploid cells.
</span>
The answer <span>Meiosis is a form of asexual reproduction which leads to more genetic variation</span>

1. If a pea plant’s alleles for height are tt, what is true of its parents?
omeli [17]
1. C) Both parents contributed a recessive allele
The offspring is homozygous for the recessive allele, which means it has two copies of it. Because each parent contributes one copy of the gene, this means that both parents contributed the recessive allele.

2. D) The offspring can be tall or short

The first cross between TT and tt will yield an F1 generation with the genotype Tt. When this generation is self-pollinated, the cross may result in the following genotypes:
TT, Tt, tt
Which means that the offspring can be tall or short.

Describe the stages of photosynthesis. Use the terms thylakoid, light-dependent reactions and light-independent reactions.
KatRina [158]

Photosynthesis in plants occurs in two stages. These stages are known as the light-dependent reactions and the Calvin Cycle.

The first stage of photosynthesis is the light dependent reactions.  These reactions take place on the thylakoid membrane inside the chloroplast.  During this stage light energy is converted to ATP (chemical energy) and NADPH (reducing power).

<span>The second stage of photosynthesis is the Calvin Cycle.  These reactions occur in the stroma of the chloroplast.  Energy from ATP and electrons from NADPH are used to convert carbon dioxide into glucose and other products.</span>

Non-protein coding DNA in eukaryotes contains repetitive elements that include (select all that apply): Group of answer choices
Olegator [25]

Answer:

interspersed, transposon-derived repeats, simple sequence repeats.

Explanation:

In the human genome, not only the protein coding genes are present, in fact these genes make up just a very little portion of the human genome about 1.5-2% of the entire human genome. Repeats make up about 48% of the human genome which is the largest and the rest include, conserved non coding sequences (43.5%), heterochromatin regions etc.  

Some of the repetitive elements includes LINEs, SINEs, DNA fossils tranposoon, Retrovirus like elements. all these are transposable elements which are  mobile DNA sequences that can migrate to different  regions/areas of the genome.

Microsatellites (simple sequence repeats) are tracts of repetitive DNA in which certain DNA motifs are repeated normally 5-50 times.
