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.

A certain plant has a color that can range from green to yellow. Some plants are very green, and some are very yellow, but most
nataly862011 [7]
Because there are not strictly green and yellow plants, this means that the color can be affected by multiple genes. If it was only affected by one gene then you would see only the two groups for the color, green and yellow. The answer is D
<span>There are several genes that control the color. </span>

Is the frog completely adapted to life on land
barxatty [35]

Answer:

No

Explanation:

There are numerous different species of frogs around the world, coming in different sizes, colors, and behaviors. All frogs though are still amphibians, practically meaning that they are animals that live both in water and land, or rather they need both in order to survive. At first look, the frogs maybe seem as well completely adapted to terrestrial life, but that is not the case, as the frogs still need water in order to be able to survive because their skin is not made to function without water for prolonged periods of time, they still have a body and limbs that are made for swimming, and they need water for hatching their eggs, as well as for the development of newly hatched frogs, as they do not have any limbs when they are born and can only swim until they develop them.
