explain how complete dominance, co dominance, incomplete dominance, and sex linked traits are inherited and expressed differentl
dlinn [17]
<span> COMPLETE DOMINANCE:
</span>
<span>Mendel concluded that some alleles are dominant and others are recessive. When one dominant allele is present, it's enough to make the recessive allele unexpressed (this is what happens in heterozygous individuals). In other words, it 'hides' or masks the recessive allele.

CO-DOMINANCE:

-a condition in which both alleles are dominant.
</span>
There are alleles that have the capacity of dominating at the same time, and when an organism is heterozygotic, both alleles are expressed.
For example, a white chicken(WW) crossed with a black chicken (BB):  100% of the offspring being WB. With this genotype, they have black feathers and white feathers.
It's not a blend of colors, but a case where both are expressing.

INCOMPLETE DOMINANCE:
-a condition with none of the alleles is dominant or recessive, so the traits blend in the phenotype.

Some alleles are not completely dominant, and when that's the case the phenotype of a heterozygous organism will be a mix between the phenotypes of its homozygous parents.

For example:
plant 1: RR -red
plant 2: rr- white

By crossing this plants we will obtain 100%  of the offspring with a color mix: pink.(genotype: Rr)
Red and white are not completely dominating so it results in a blend of colors.

SEX LINKED TRAITS

Sex chromosomes contain genes that determine the sex of a person. Two X chromosomes result in a female and one X plus a Y result in a male.

In those chromosomes, there are genes specific for each gender, and in those chromosomes, there are genes that code for certain traits- the sex-linked traits.
These traits will be inherited according to the sex chromosomes they receive from their parents.

A 51-year-old woman who was born congenitally blind and deaf is able to distinguish individuals by a light touch of the individu
icang [17]

Answer:

The correct answer will be option-B

Explanation:

Meissner corpuscles are one of four types of mechanoreceptors which response to mechanical pressure.

The corpuscles are very adaptive and sensitive receptors which convert the stimuli to action potential and send them to the Central nervous system.

The corpuscles are found in the areas which are exposed to touch or are sensitive to touch like in the fingers of the hand and the lips.

Since the deaf and blind lady distinguishes people with a light touch, therefore, these Meissner corpuscles are involved in helping identify the individuals.

Thus, Option-B is the correct answer.

Heterotrophs obtain chemical energy from ______________.
loris [4]

Answer:

Heterotrophs obtain chemical energy for their survival by eating plants and animals.

Explanation:

  • The chemical energy that organism need comes from food. They break this food down to obtain energy.
  • Depending on their source of nutrients , they are classified into: Autotrophs and Heterotrophs.
  • Autotrophs use sunlight and photosynthesize to produce their own food. They are often known as producers.
  • Heterotrophs are beings that can't prepare their own food and consume other organisms to obtain energy.They are also called consumers.
  • Examples include: Animals, fungi,etc.
