How is a recessive allele different from a dominant allele?

1 answer:

4 0

Answer: 1) Recessive allele is unable to express its effect in the presence of dominant allele WHILE a dominant allele is able to express itself even in the presence of its recessive allele.

2) Recessive allele produces its phenotypic effect only in the presence of a similar allele. E.g; tt is dwarf. WHILE a dominant allele does not require another similar allele to produce its effect on the phenotype. E.g; Tt is tall.

3) Recessive allele forms a defective polypeptide or enzyme so that the expression consists of absence of the effect of dominant allele. E.g; white flower colour in Pea. WHILE a dominant allele can form a complete polypeptide or enzyme for expressing its effects. E.g; red colour of flower in Pea.

<h3>What is evolution?</h3>

Evolution is the shift in a biological population's heritable traits over successive generations. These traits are the result of genes that are expressed during reproduction and transferred from parent to offspring. Mutation, genetic recombination, and other causes of genetic diversity frequently result in different traits existing within a population. When these variations are subjected to evolutionary processes like natural selection (which includes sexual selection) and genetic drift, specific traits within a population start to become more or less prevalent. This is when evolution happens.

Why might a water table drop

bonufazy [111]

Pumping water out of the ground faster than it is replenished over the long-term causes similar problems. The volume of groundwater in storage is decreasing in many areas of the United States in response to pumping. Groundwater depletion is primarily caused by sustained groundwater pumping.
