How recombining of genetic information leads to offspring that exhibit genetic variability?

∙ 11y ago
Recombining of genetic information (crossing over) during prophase I of meiosis results in every chromosome being a combination of the person's mother's and father's genetic information.
Recombination of genetic information in an offspring takes place at the time of gametic union forming the zygote. The genetic variability depends on the extent of heterozygocity present in the population of that species. Role of crossing over is limited to the extent of frequency of genes present in an individual to produce variety of gametes.

How do you find possible phenotypes of offspring?
Mendel Diagrams. If the offspring gets a dominate gene from both parents, the offspring will exhibit traits from the dominate gene. If the offspring gets a dominate gene from one parent and a recessive gene from another, the offspring will exhibit traits from the dominate gene. If the offspring get a recessive gene from both parents, the offspring will exhibit traits from the recessive gene.
Individuals must exhibit a trait in order for it to appear in their offspring true or false?
False. if that was the case there can be no development.
Blood type A marries blood type B their offspring exhibit?
It is possible for their offspring to exhibit type AB, A, B, or O, depending upon the parental genotype, which is unknown. The blood type exhibited, also referred to as phenotype, is due to the dominant A and B alleles. Every person inherits two alleles for each gene, one from each parent. The type A may have inherited two A alleles or an A allele and an O allele, the O being masked by the dominant A because it is a recessive trait. Therefore they exhibit the phenotype A, but could potentially pass on an O allele to any offspring. The same goes for the type B parent (could be BB or BO). The exact genotype (AA/BB or AO/BO) is not determined through simple blood testing, so the exact phenotype of the offspring can not be predicted.
Do bacteria exhibit homeostasis?
All organisms exhibit homeostasis.
Which process usually results in offspring that exhibit new genetic variations?
Assuming you mean genetic traits different from the parents and likely novel in the gene pool, the answer is random mutation.

Why do older machines generally exhibit a higher degree of natural variability than do the newer machines?
The extent of natural variabilty inherit in a process differs from process to process, and changes over time.As the older machines will genrally exhibit a higher degree of natural variability than the newer machines, partly because of worn parts and partly because of newer machines may incorporate designes improvements that reduce the variability of their output.
If both parents are heterozygous for polydactyly what percentage of offspring will exhibit polydactyly?
75%
Why do offspring formed by asexual reproduction exhibit similarity?
They share the same genes
What percentage of the offspring in a cross between parents with the genotypes EE and EcEc will exhibit cataracts?
50
Does corn exhibit certain traits?
It does because the corn plants that it reproduced from have the same traits as there offspring.
Type you survivorship curves are typical of species that exhibit?
few offspring and good parental care
Individuals must exhibit a trait in order for it to appear in their offspring true or false?
False. if that was the case there can be no development.
When studying organism why it important to study more than one member of a species?
variability. individual organisms exhibit different characteristics due to their unique genetic makeup.
What is the probaility that the offspring of a homozygous dominant individual and a homozygous recessive individual will exhibit the dominant phenotype?
100 percent.
What Organisms that produce offspring several times over many seasons exhibit a life history adaptation called?
iteroparity
What is a Term for the condition in which hybrid offspring exhibit a phenotype that is midway between the dissimilar traits of parent organisms?
Incomplete Dominance.
