2.Which of the following represents a genetic cross between 2 individuals that are each heterozygous for both traits?

wariber [46]

Answer:

A. AaBb x AaBb

Explanation:

The term heterozygous refers to the presence of two different alleles of same gene in an organism. The one allele can be of wild type (original type) and one can be mutated or newly formed.

In the question, two traits are represented by two letters, A and B and alleles as A and a and B and b, respectively. We are asked about a cross involving two traits and two individuals in such a way that both are heterozygous.

If we look at option A, AaBb x AaBb,

we see that one trait A and the other trait B is in heterozygous form (Aa and Bb) in both individuals.

If we look at option B. AABB x AABB

we see that one trait A and the other trait B is in homozygous form form (AA and BB) in both individuals. Homozygous means when the alleles are same for each trait in an individual.

If we look at option C,Aa x Bb

There are not two traits, one trait of one individual and other trait of other individual is being crossed that is not possible.

If we look at option D. AAaa x BBbb

Again, the individuals are homozygous for two traits.

Therefore, A is best option.

Hope it helps!

The vector, which is often a small, circular piece of dna that can exist outside the bacterial chromosome, is known as what?.

kramer

The vector, which is often a small, circular piece of dna that can exist outside the bacterial chromosome, is known as a plasmid.

Bacteria and certain other microscopic species contain plasmids, which are tiny circular DNA molecules. Physically distinct from chromosomal DNA, plasmids multiply on their own. They normally contain only a few genes, including some linked to antibiotic resistance, and they can spread from one cell to another.

Recombinant DNA techniques are used by scientists to splice the genes they want to research into a plasmid. The inserted gene is duplicated along with the plasmid when it duplicates itself. Molecular cloning, the process of creating DNA molecules and introducing them into a host cell, uses plasmid vectors as the means of delivering recombinant DNA into the host cell.

To know more about plasmids, refer to the following link:

What are Flatworms?..

Margaret [11]

Flatworm, also called platyhelminth, any of the phylum Platyhelminthes, a group of soft-bodied, usually much flattened invertebrates. A number of flatworm species are free-living, but about 80 percent of all flatworms are parasitic—i.e., living on or in another organism and securing nourishment from it.

What is product of meiosis 1

melisa1 [442]

Answer:

haploid daughter cells

Explanation:

Meiosis involves two divisions of the parent cell resulting in four daughter cells. Each daughter cell has half the number of chromosomes as the parent cell. In meiosis I, the number of chromosomes is reduced by half thus called reduction division. The product of meiosis I is two diploid daughter cells.
