Black fur (B) in guinea pigs is dominant over white fur (b). What is the probability of finding homozygous black offspring in a

cross: BB x BB?

Svet_ta [14]1 year ago

Answer: 100%

Explanation: If both guinea pigs are BB dominant, that means they don't have the recessive trait, so therefore no heterozygous guinea pigs will be created. This leaves 100% homozygous offspring.

Discuss the functions and deficiency symptoms of phosphorus​
Angelina_Jolie [31]

Answer:

Functions of phosphorus in the body,

i) Formation of bones and teeth. It's a component necessary for forming strong bones and teeth in the body.

ii) It's important in helping to make protein in the body for growth. Since many proteins in the body are phosphorylated for regulating their functions.

iii) Activation of enzymes. This done through phosphorylation.

iv) Gene transcription. It provides structural importance to the gene and protein binding is by the presence of phosphorus.

Deficiency of phosphorus in the body;

i) Weak and fragile bones.

ii) Bone pain.

iii) Fragile teeth.

iv) Stiff joints.

Indicate, as true or false, whether each of the following statements about species is a component of the biological species conc
adell [148]

Their reproductive isolation from each other is complete: False  

They are unable to produce hybrid offspring upon interbreeding: True  

They shared a common ancestor recently in evolutionary time: False  

Explanation:

A species known as a group of that organisms which can be potentially interbreed with another one to produce viable, fertile offspring. Prezygotic and postzygotic barriers separated the species from each other. It prevents the mating of viable fertile offspring.  

This process happens when groups in that species become reproductively diverge as well as isolated. In the formation of new species postzygotic and Prezygotic barriers play vital role.

Ksivusya [100]
The last Caribbean monk seal that died was the last member of a SPECIE.
All the living things, both plants and animals are placed in a hierarchical order depend on their characteristics and specie is the least stage on that rank. A specie refers to a specific group of animals which share similar physical characteristics. The Caribbean monk seal for instance is one of the specie of fishes that exist on earth.Thus, a specie is a basic unit of classification which recognize animals of the same sort.<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
