What is a pair of nonidentical alleles affecting two phenotypes for a given trait are both expressed at same time in heterozygotes?
Codominance is when a pair of nonidentical alleles at a gene locus both affect the phenotype in heterozygotes, and therefore both alleles are expressed simultaneously. This results in the expression of a unique phenotype that is a combination of the traits associated with each allele.
Why some phenotypes are the same and other phenotypes different?
because no one in this world has the same gene.They may have similar gene,but not the same
What is different in phenotypes of an individual from those in the same species?
Phenotypes are the characteristics of the genes that are most dominant, and can represent themselves. Species have many different genes for example, you dont have the exact same genes as your best friend, and thus, producing different phenotypes which is why you look different... However, you do have may similar genes that make you part of that species.
What is the term that refers to the fact that the same genotype can be associated with many different phenotypes?
Genetic Recombination, for but one example. A Gene, with It's precisely packaged Information is, as it turns out, open to biochemically controlled Interpretation [phenotypes]!
Why do you have more genotypes than phenotypes?
The number of possible genotypes is typically higher than the number of observable phenotypes because multiple genotypes can result in the same phenotype due to genetic variations, interactions, and environmental factors. Different combinations of genotypes and environmental influences can lead to similar outward traits, resulting in fewer distinct phenotypes than genotypes.
What is it when genes for a trait are the same it is called homozygous or?
heterozygotes

Distinguish between parental and recombinant phenotypes?
Parental phenotypes are the phenotypes that are seen in the offspring that are the same as the phenotypes of the parents. Recombinant phenotypes are the phenotypes that are the result of recombination events during genetic crossing, resulting in combinations of traits not present in the parents.

An organism that has two diffrent alleles for a trait?
Is called a heterozygote (hetero- meaning different, and zygote being the sex cell). Heterozygotes have two different alleles of a particular gene, one in each of their sets of chromosomes. As apposed to homozygotes which have two of the same alleles of a gene.
How can you have the same phenotype but different genotype?
Different genotypes don't always change your phenotypes because of mutations
What might the phenotypes be of two organisms that were found to have different genotypes but the same phenotype?
If two organisms have different genotypes but the same phenotype, it means that they share the same observable traits even though their genetic makeup differs. This could occur if the same phenotype can result from different combinations of alleles, known as genetic heterogeneity. So, while the genetic basis of their traits is different, they both exhibit the same physical characteristics.
Why are there so many phenotypes in polygenic inheritance?
Polygenic means many genes are influencing one trait. So, the inheritance of this gives you are all sorts of combination of genes that are expressed in various phenotypes. As example think of the different heights of siblings. There are 5 to 7 genes that influence height and in the same relative environment of siblings you get many combinations of those genes which express themselves in different height same sex siblings.
What’s the difference between genotype and phenotype?
Genotype are the unseen differences in genetic combinations of an individual. Phenotypes are the expressed and seen differences of an individual.A genotype is the genetic makeup of an organism with reference to a single trait, set of traits, or an entire complex of trait; that is, genotype is the type of genes you have. A phenotype is the physical characteristic of an organism. So the genotype decides the genetics and inherited traits of an organism, but phenotypes refer to the actual display of these traits. Genotypes are decided by inherited genes, while phenotypes are determined by the effect of environmental factors as well. The more complex a biological process, the more is the effect of environmental factors on it and therefore the chances of a predominant phenotype.For example, say recessive allele t codes for albinism (a congenital disorder) and dominant allele T is normal. Two individuals have different genotypes: TT and Tt. Because they both have an allele T, neither have albinism; therefore, they have different genotypes but the same phenotype. An individual with a genotype tt would have albinism and would therefore have a different phenotype than the previous two.Another example: Identical twins have the same genes and the same genotype. Every now and then a gene in one of the twins will be expressed differently from the gene in the other twin. They will have different phenotypes. So phenotype is a fancy word used when a gene works one way under certain conditions and a different way under other conditions.An easy way to remember that (from what I've learned from my science teacher) is to think "Pheno" as "Photo", like if you take a picture, you'll only be able to see the outside of somebody; what they look like..In more detail:Take alleles R and r. If R and R display a "complete dominance" relationship, then RR , Rr, and rr are different genotypes, but two are the same phenotype. RR and Rr display the same trait because R is completelycovering up r's trait, but rr will show the recessive trait.EX: A flower with R as a red trait and r as a white trait has the following phenotypes for each genotype:RR: redRr: redrr: whiteAdditional information:If R and r display a "codominance" relationship, then RR, Rr, and rr are different genotypes and phenotypes. RR shows the dominant trait, while rr shows the recessive trait. Rr shows a combination of the two, as if the two were dominating cooperatively.EX: A flower with R as a red trait and r as a white trait has the following phenotypes for each genotype:RR: redRr: red and whiterr: whiteIf R and r display a "incomplete dominance" or "incomplete inheritance" relationship, then RR, Rr, and rr are different genotypes and phenotypes. RR shows the dominant trait, while rr shows the recessive trait. Rr shows when R incompletely dominates r, allowing some of its qualities show. EX: A flower with R as a red trait and r as a white trait has the following phenotypes for each genotype:RR: redRr: pinkrr: white
Is the new iPad and the iPad with retina display the same?
Mostly. Note they both have the same retina display. The iPad with Retina Display has the A6X chip which does have better performance than A5X in New iPad.
