Answer:

Mendel's law of independent assortment states that the genes are separated and inherited independently of each other into the gametes.

The corn can be used to study the law if independent assortment as each kernel of the corn is its fruit. Thus, it is a result of sexual reproduction.

Single corn may contain 800-1000 kernels which may have different shape, texture, structure et cetera as result of independent assortment, that is, each kernel receives alleles of genes independent of each other.

For example, a gene responsible for the texture of kernel would be inherited independently of the gene responsible for the color of the kernel.

this is a great example how brothers and sisters don't look exactly like you. each pair show dominance or segregation independently. when chromosomes make pairs or tetraploid, they arrange in variety of ways. one child would have mom*s eye color and mom*s hair color, while other child*s chromosomes arrange in a way the he has mom*s eye color and dad*s hair color. they arrange in many different ways, that*s why you call that they segregates independently from each other.

Arlecino [84]

Answer: Annelida

Leeches are soft bodied segmented parasitic worms. They belong to the phylum Annelida. They are hermaphrodites which means they exhibit sex organs of both male and female.

The characteristics which are found in leeches which group them into Annelida are:

1. The body of the leeches are bilaterally symmetrical like other Annelids. The body organs are also segmented.

2. They have a closed circulatory system in which the heart pumps the blood to all the parts of the body.

3. Leeches either exhibit a protusible pharynx or proboscis which allows them to suck the blood of the host such features are also common in other Annelids.

Match each scenario to its related biomolecules. Jack is eating a diet that will help him build muscle, so he eats a diet high i

Stells [14]

The options for this question are as follows:

A. Nucleic acids

B. Carbohydrates

C. Fats

D. Proteins

Now the correct answers of the match are as follows:

Jack is eating a diet that will help him build muscle, so he eats a diet high in this. D. Proteins

Explanation: Proteins help to build up the muscles. That's why people who want to do body-building, eat protein rich foods, like chicken, eggs, soy, etc.

Before a race, Ruth drinks a beverage full of this biomolecule to get energy. B. Carbohydrate

Explanation: This biomolecule provides instant energy to our body. For example, glucose is consumed before race, as dissolves quickly in our blood and provides instant energy. Glucose is an example of simplest carbohydrate.

These molecules in olive oil will help Ruth’s body store long-term energy. C. Fats

Explanation: Fats are the kind of biomolecule which is stored in our body in the adipose tissues. Also, when glucose is all used up by our body cells, the body starts to get energy from this stored fat.

Elizabeth has been advised to go for genetic screening to detect any abnormalities in her unborn child. A. Nucleic acids

Explanation: Every cell of our body has DNA, and it contains all the genetic information about the whole body. DNA is a kind of nucleic acid. If Elizabeth is going for test of the abnormality, it means she is going to test for the DNA of her child.

Tall pea plants are dominant, while short plants are recessive. In a cross between a purebred tall plant and a purebred short pl

zloy xaker [14]

Answer:

1. tall (or heterozygous)

2. 3:1

3. carriers

4. Each parent organism contributes one copy of its alleles in a seemingly random fashion to its offspring, as meiosis to create gametes (egg or sperm cells) reduces the number of genes by half. Therefore, each gamete contributes only one allele.

5. A Punnett square is a diagram used to map out the possible genotypes of a child given the genotypes of its parents. In a Punnett square, the genotype of one parent is listed in the first row of the square, and the genotype of the second parent is listed in the first column. Then, in the middle squares, all possible genotypes of their offspring are listed, and the phenotypes are calculated using the law of dominance.

6. Purebred strains of organisms always produce heterozygous offspring in the first generation, with all members of the first generation exhibiting the dominant trait for the gene of interest. The second generation typically has a 3:1 mix of dominant and recessive phenotypes, respectively.

7. Punnett squares predict that the second generation of two distinct purebred homozygotes for a trait will have a 3:1 ratio of dominant to recessive traits. Mendel did careful statistical analysis on his hybridization experiments and found that, for each of his seven characteristics of interest, the ratio was approximately, but not exactly, 3:1. Therefore, Mendel's experimental observations match the predictions of Punnett squares quite well.
