In pea plants, the gene for the color of the seed has two alleles. In the following Punnett square shown below, the dominant all

Bogdan [553]

<h2>Question 1.</h2><h2>Answer:</h2>

The correct answer is option D which is 100%.

<h3>Explanation:</h3>

According to the description of Punnett square given in the question, there will be there will be two types of genotype and one type of phenotype which is yellow.

YY, homozygous dominant = Yellow Seeds.
Yy, heterozygous = Yellow Seeds
So the progeny will be 100% of yellow seeds.

Punnett square is also attached.

<h2>Question No.2.</h2><h2>Answer:</h2>

The correct answer is the option A which predicts the genotypic and phenotypic probabilities of possible.

<h3>Explanation:</h3>

<u><em>Punnett square is a way to determine the probable genotype of expected offspring by the genotypes of father and mother devised by Punnett.</em></u>

In this method, A square shaped table is constructed and the alleles of the gene of father/male are written on the top of tables, on the column.
The alleles of the mother are written in horizontal to square, in front of rows.
So the genotypes in the square box by multiplying row and column alleles will be expected genotype of an offspring.
The example is attached below.

<h2>Question no. 3.</h2><h2>Answer:</h2>

The correct answer is option C which is 1 = TT; 2 = Tt; 3 = Tt; 4 = tt .

<h3>Explanation:</h3>

The Punnett square is made by the description given in the question.

There are total 4 boxes. In box number 1 which is on top left genotype is TT and in box 2 which is on top right genotype is Tt. In box 3, the genotype is Tt and in box 4, the genotype is tt.

So according to the given Punnett square information in option C is correct one.

According to the octet rule, if an atom has fewer than 8 electrons in the outer most energy level, what is likely to happen?

Sliva [168]

According to the octet rule, If an atom has fewer than 8 electrons in the outer most energy level, it will react with other nearby atoms to give, receive or share electrons until it has a full outer shell. Option D.

<h3>What is the octet rule?</h3>

The octet rule is a theory stated by Lewis (1917) and is used to explain how atoms are combined.

The theory explains how atoms from different elements tend to complete their outer energy layer with 8 electrons to reach a stable electronic configuration.

The ions of different chemical elements complete their last energy levels when combined with other atoms.

Atoms can either gain or share electrons with other atoms to compose the molecule,

High electronegativity elements gain electrons until they get to complete the octet.

Low electronegativity elements lose or share electrons to get to the octet.

In this way, the rule explains how atoms form bonds to create a molecule.

The rule is used to predict the behavior of several substances according to their electronic configuration.

Among the options, the correct one is option D. <em>if an </em><em>atom</em><em> has fewer than 8 </em><em>electrons</em><em> in the outer most</em><em> energy level</em><em>, it will react with other nearby atoms to give, receive or share electrons until it has a </em><em>full outer shell.</em>

WILL GIVE BRAINLIEST!

oksian1 [2.3K]

The answer is D. The dark mice could not camouflage on the white beach sand hence were more conspicuous. Therefore, the Predators were able to easily spot them and prey on them. Therefore, the phenotype of dark mice reduced in the population since most mice were not able to reach maturity and pass down their traits. The allele for white fur, therefore, increased in the population. This is the process of natural selection at work.
