Which of the following is an advantage of sexual reproduction over asexual reproduction?
It is generally though that sexual recombination is the greatest advantage of sexual reproduction over asexual reproduction. By recombining genes you get many variants that may have some members of the population resistant to some environmental challenge. Asexuality just gives clones.
What is heterozygouz?
Many organisms contain two copies of each chromosome, and generally these two chromosomes are not identical. If a particular trait, such as the shape of a pea, is determined by one particular section of a chromosome, it is possible for the two copies of the chromosome to have different instructions for the trait. If the two sections of the two chromosomes have different instructions, this is called being heterozygous.Often if an organism is heterozygous for a trait, one of the sets of instructions (called an allele) will be dominant over the other. This means that if either of the chromosomes has that dominant version of the allele, that is the set of instructions that will be followed.Examples: The gene for seed shape in pea plants exists in two forms, one form or allele for round seed shape (R) and the other for wrinkled seed shape (r). A heterozygous plant would contain the following alleles for seed shape: (Rr).Organisms have two alleles for each trait. When the alleles of a pair are heterozygous, one is dominant and the other is recessive. Using the previous example, round seed shape (R) is dominant and wrinkled seed shape (r) is recessive. Round: (RR) or (Rr), Wrinkled: (rr).
Which of the following organisms has an exterior that is radially symmetric a snake?
A starfish
Who of the following researchers is considered to be the father of sexology?
Alfred Kinsey
Which of the following best describes why the process of evolution is easier to study in fruit flies than in birds?
Because fruit flies have small cell counts Because the life cycle of a fruit fly is short enough to actually see a change in a short period of time. With larger animals, it could take many years to see an actual change. With fruit flies, you can see many generations of change in a shorter period of time.
Which of the following substances is not contained in a chromosome?
Polymerase
Describe four types of mutation resulting from the breakage of chromosome?
Deletion: a segment of the chromosome is lost during breakage. Duplication: a segment of the chromosome is copied and inserted back into the chromosome following breakage. Inversion: a segment of the chromosome is reversed and re-inserted following breakage. Translocation: a segment of the chromosome breaks off and joins a different chromosome.
What deos descendants mean?
Generations following an individual.
List by order size the following gene gene pool genome chromosome?
order from largest to smallest: gene, genome, chromosome, DNA, gene pool
Is a visual tool for following a trait through generations of a family?
The answer is: pedigree
How many chromatids per chromosome exist following anaphase 2?
Meiosis refers to a type of cell division that results in 4 daughter cells. In meiosis II, there is only 1 chromatid per chromosome that exists following anaphase II.
How to construct a portfolio with Wisdom Tree funds?
One can construct a portfolio with WisdomTree by following the portfolio guide on the official website. If one gets stuck, customer support is always available to provide help.
What is the definition of traditional architecture?
traditional architecture is the ability to construct or built any structure following cultural aspects and regulations
How does crossing over create genetic variety in offspring?
The crossing over makes more room for variability. When the chromosomes swap traits, they create different combinations of traits. The different combinations causes more variations in the products.
What is needed in order to construct a kids pottery wheel?
The things that are needed in order to construct a children's pottery wheel would be the following products: a small working motor, plywood to create the frame, foot pedal, bearings, and flywood.
Can you arrange the following in order from largest to smallest in size DNA NucleotideNucleuscell chromosome?
From smallest to largest: DNA (where DNA = short sequences of nucleotides) gene chromosome nucleus sperm cell
A typical human male has the following sex chromosome pair?
The sex chromosomes of a man are XY (vs. XX for a woman).
