8. What does being called a “carrier” for a specific trait mean?

Biology

sukhopar [10]3 years ago

It means you have the genetics for the trait but you do not express the trait. Someone who is a carrier could not have a disease, but have offspring that does have that disease. This is because of alleles, which can be upper or lower case letters, upper being dominant traits and lower being recessive. Many genetic diseases are recessive so if a person has the genotype Rr they will carry the disease but if they have rr they will have the disease. If I were you id research how punette squares work

A major difference between the eccrine sweat glands and the appocrine sweat glands is that eccrine glands empty into/onto ______
Vlad [161]
<span>A major difference between the eccrine sweat glands and the appocrine sweat glands is that eccrine glands empty into/onto the skin surface while apocrine glands empty into/onto the hair follicle.
There are two types of sweat gland, eccrine and apocrine. As the eccrine glands empty into the skin surface, they are present all over the body particularly on forehead, palms and feet. That's why we feel more sweat on these parts of the body. while apocrine glands empty into/onto the hair follicles so they are mostly armpits.</span>

For what purpose is mitochondrial genomics used
bezimeni [28]

<span>The mitochondria are famously known as the powerhouse of the cell since it is the one that gives the cells energy that is also used by the human being.  This energy conversion is called oxidative phosphorylation. Mitochondria are found in eukaryotic cells, including humans.  These organelles also had its own genome, or what we called as DNA which is known as mitochondrial DNA, or mtDNA which is present in the mitochondrial matrix.  The role of mtDNA or mitochondrial DNA is to convert the energy from food into any other forms that it thinks the cell can use.  It is containing 37 genes which are all necessary for a normal mitochondrial function.</span>

In a population of rabbits, there are 496 black rabbits and 27 white rabbits. Fur color is determined by a pair of alleles where
Troyanec [42]

Answer:

0.96

Explanation:

It is given that

B is the dominant allele which represents the black color

and b is the recessive allele which represents the white fur.

B being dominant will result into black color fur for genotype "Bb"

Given -

Frequency of black fur allele (p) is 0.8

As per Hardy Weinberg's  first law of equilibrium

p + q = 1\\

Substituting the value of p in above equation, we get -

q = 1-p\\q = 1-0.8\\q= 0.2

q represents the frequency for white fur allele

Frequency of white fur phenotype is

q^2\\= 0.2^2\\= 0.04

Frequency of homozygous black fur phenotype (BB) is

p^2\\= 0.8^2\\= 0.64

As per Hardy Weinberg's second law of equilibrium -

p^2 + q^2 + 2pq = 1\\0.64 + 0.04 + 2pq = 1\\2pq = 1 - 0.68\\2pq = 0.32\\

Combined frequency of homozygous and heterozygous black fur phenotype is

0.64 + 0.32\\= 0.96
