What happens in crossing over? Why is it important for sexually reproducing organisms, and what is one of the consequences of er
BaLLatris [955]

Answer:

Crossing over increases the genetic variation  

Errors in crossover formation result in chromosomal rearrangements (duplications and deletions) and may also cause chromosome nondisjunction

Explanation:

Crossing over, also known as recombination, refers to the exchange of genetic material (DNA) between non-sister chromatids of homologous chromosomes during meiosis. Crossing over increases the genetic variation of the resulting gametes, allowing different genetic combinations to be passed from parents to offspring. Unequal crossing over is a type of error associated with chromosomal duplication and/or deletion events. Unequal crossing over occurs when homologous sequences are not paired precisely. Moreover, errors in crossing over may also cause chromosome nondisjunction, thereby leading to aneuploidies.

Luminance response can be tested with a(n) _____. i. near-range photometer ii. telescope photometer iii. illuminance meter
Furkat [3]

Luminance response can be tested with an option(d) I or II i.e, near range photometer or telescope photometer.

The luminous intensity per unit area of light traveling in a specific direction is measured photometrically as luminance. It indicates how much light enters, exits, or is reflected from a specific area and falls within a specified solid angle.

The visual system's ability to function depends heavily on luminance and contrast. Vision is impossible without light (luminance = 0), and without contrast, we are unable to see spatial or temporal patterns. The first stage in seeing, which enables all other visual processes, is the capacity to respond to brightness.

A photometer is a tool used to gauge light's characteristics. A photometer can be used to measure a light source's brightness, color, and flux among other attributes. Photometers gather radiation released by the light source to determine the wavelengths of light and atomic emissions.

The complete question is:

Luminance response can be tested with a(n)_____.

I) near-range photometer

II) telescope photometer

III) illuminance meter

A) I only

B) II only

C) III only

D) I or II

Which of Thomas hunt morgans hypotheses was valid
Simora [160]
<h3><u>Answer;</u></h3>

white eyes are homozygous recessive

<h3><u>Explanation</u>;</h3>
  • <em><u>Thomas Hunt Morgan work with the fruit fly showed that genes are linked in a series on chromosomes and are responsible for identifiable, hereditary traits. </u></em>He was the first to identify that genes are linked to the same chromosome.
  • <em><u>According to his hypothesis he stated that genes that are linked are arranged linearly on a chromosome, while those genes with low combination frequencies must be closer together and thus difficult to separate</u></em>.
  • When a gene contains two similar alleles that is, either two dominant alleles or two recessive alleles then it is called homozygous dominant and homozygous recessive respectively. White eyes of a fruit fly is an example of homozygous recessive
