Suppose you have monohybrid flowers in your garden and find that they produce black seeds to brown seeds in the ratio of 3:1. If

Dvinal [7]

Hybrid = having one recessive and one dominant allele
This means that all of the flowers must have the genotype Bb.
Knowing this, let's make a Punnet Square.

$\begin{tabular}{ l c } & B \ \ \ \ b\\ B & \boxed{BB}\boxed{Bb} \\ b & \boxed{Bb\ }\boxed{\ bb} \\ \end{tabular}$

As you can see, 3 of these are going to have the dominant trait and 1 is going to have the recessive trait. This corresponds to our 3:1 in our question, meaning that the black seeds must be dominant and the brown ones recessive.

Because they are dominant, the genotype for black seeds could be BB <em /><em>or</em> Bb.

kirill115 [55]

Ans.

HD (Huntington's disease) is a genetic neurological disorder that occurs due to damage and death of brain cells. it is caused by an autosomal dominant mutation in HTT (huntingtin) gene, having a trinucleotide repeat section that makes HTT protein.

The mutation leads to an increase in this nucleotide repeat count, associated with formation of altered or mutated huntingtin protein. These altered proteins show deleterious affect on brain cells and result in Huntington's disease.

Thus, the correct answer is 'option A). a mutated gene.'

What are the differences in the way lipids are found or function in plants and animals?

GalinKa [24]

Lipids are stored as triacylglycerols and waxes on both animals and plants

<h3>What is lipids ?</h3>

Lipid can be described as an organic compound that is not soluble in water. lipid is an essential component that is needed for proper functionality in both plants and animals.

In plants, lipids help provide lots of energy that is needed for different metabolic processes that goes on in the plant. Lipids also help fight off pathogens in plants

In animals, lipids also serve as an energy source and they help in the regulation of the different hormones present in the body. Lipid also help signal important molecules when they are required in the body and they also help in the proper digestion of food molecules.
