Differentiate between parental and recombinant gametes.

1 answer:

6 0

Answer: The two types of gametes are possible for when they are following genes that are on the same chromosomes. If they are crossing over, it does not occur, the products are known as Parental Gametes. If they are crossing over, the products are Recombinant Gametes. It is usually the simple matter that determine which of these gametes are recombinant gametes.

The difference between these two genes, is that are far apart and the frequency of recombination of genes is fifty percent. These genes that are closely located on the chromosome exhibit only have a few cross overs. The gametes that have recombined chromosomes, are known as Recombinant Gametes while the Parent Gametes are carrying on non-recombinant chromosomes.

I hope this helps you!

evablogger [386]

Answer:

3) 0.75m/s

Explanation:

The wavelength of a wave is calculated using the formula;

λ = v/f

Where!

λ = wavelength of wave (m)

v = velocity or speed (m/s)

f = frequency of wave (Hz)

According to this question, one end of a rope is vibrated to produce a wave with a wavelength (λ) of 0.25 m and frequency (f) of 3.0 Hz.

Using λ = v/f

v = λ × f

v = 0.25 × 3

v = 0.75m/s.

which of the following is not an abiotic factor in the prairie ecosystem a water b sunlight c grass d soil

Lapatulllka [165]

Answer:

Grass

Explanation:

Biotic means living. There are some obvious abiotic factors here. The only gray area is what "soil" encompasses

grass-Biotic means living, all of the other choices are not living, and would therefore be abiotic factors

This is because it is a living thing (performs photosynthesis and cellular respiration).

Biotic means living, all of the other choices are not living, and would therefore be abiotic factors

Viefleur [7K]

Answer:

They are used as an indicator organism for pathogenic bacteria.

Explanation:

Coliforms are bacteria found in digestive tract of animals and humans. They are non-pathogenic, easy to culture and are used as an alternative indirect testing for presence of other microorganisms. Coliforms thrive in exact environmental conditions like other pathogenic bacteria, thus often used to indicate whether they are bacteria found in drinking water and swimming pools that might end up causing infections.

Therefore the existence of coliforms in water easily indicates feacal contamination.

Comparative morphology ______.

Ivanshal [37]

Answer: analysis the similarities and differences between organisms of the same species

Explanation:

Comparative morphology is analysis of the patterns of the locus of structures within the body plan of an organism, and forms the basis of taxonomical categorization. Functional morphology is the study of the relationship between the structure and function of morphological features.
