In Labrador retriever dogs, coat color is determined by the interaction of two genes (pigment and deposition of pigment). This i

s called epistasis. Coat color can be black (B) or brown (b) and deposition of pigment into the hair shaft is deposited (E) or not deposited (e). If a retriever has the genotype where they have _ _ ee, then they will have a yellow coat regardless of what color they inherit (e.g., Bbee or bbee gives a Yellow lab).
1. Calculate the phenotypic ratios of a cross between a male and a female Labrador retrievers that are both heterozygous for coat color and heterozygous for deposition of pigment.

What is the genotype of both the male and female parents?

What are the possible gametes of both the male and female parents?

What is the phenotypic ratio of the offspring?

Answer 1,2,3,4:

As both are heterozygous therefore Male genotype will be (BbEe) and the genotype of female will be (BbEe). While both will have the phenotype black.

Parent Genotype

Male X Female

BbEe X BbEe

Possible gametes from Parents

Male X Female

BbEe X BbEe

(BE) (Be) (bE) (be) X (BE) (Be) (bE) (be)

...

F1  generation will have following genetypic ratio

Black Labrador = 9  = B_E_

Brown Labrador = 3  = bbE_

Yellow Labrador = 3  = B_ee

Yellow Labrador = 1  = bbee

Furthermore, the phenotypic ration will be

Black Labrador = 9

Brown Labrador = 3

Yellow Labrador = 4

What does it mean if a population is in Hardy-Weinberg equilibrium? Be specific.
Andrej [43]

Answer:

The Hardy-Weinberg law states that in a sufficiently large population, in which matings occur randomly and that is not subject to mutation, selection or migration, gene and genotypic free frequencies are kept constant from one generation to another, once a state of equilibrium has been reached, which in autosomal loci is reached after one generation.

It is said that a population is in equilibrium when the alleles of the polymorphic systems maintain their frequency in the population throughout the generations.

As seen in the video game death stranding.
Two extinction level events happened and wiped out half of all human life. Building and cars and homes were destroyed and replaced by growling grass or dirt. A new species of bug came about called a cryptobite and a bridge was formed between the world of living and dead and hence forth came the rise of beached things

Diagram of gastrulation and neurulation?
kozerog [31]
Following gastrulation, the next major development in the embryo is neurulation, which occurs during weeks three and four after fertilization. This is a process in which the embryo develops structures that will eventually become the nervous system

The pathway between the ventral tegmental area (VTA) and the _____ is critical for the addiction process because lesions to this
Airida [17]

The pathway between the ventral tegmental area (VTA) and the Nucleus Accumbens is critical for the addiction process because lesions to this pathway eliminate addiction. It is a part of the brain.

<h3>What is the nucleus accumbens?</h3>

The nucleus accumbens refers to a part of the forebrain located in the hypothalamus.

The nucleus accumbens is an interface between motivation (i.e., stimuli) and the corresponding action (response).

The nucleus accumbens is fundamental in different responses such as, for example, rewards, stressful situations, drug behavior, etc.
