What describes the phenotypic plasticity of an organism best? O the degree of which individuals can change over time by altering their genotype O the effect of variable environment on the genotype of an organism O the variation of the target phenotype for a given genotype in different environments O the change of a phenotype due to ingestion of detrimental plastic material (as for instance plastic straws by sea turtles). O the degree of which a given genotype is adapted to a particular environment

How can you recognize codominance? The alleles affect more than one trait. O The trait exhibits continuous variation The heterozygote expresses the phenotypes coded for by both alleles O The phenotype of the heterozygote is intermediate between the phenotypes of the homozygotes. 梦 24 近

Based on the information shown in the chart above, what is the most likely inheritance pattern for the 'forked bristles' trait? why?
When organisms reproduce and their offspring demonstrate co-dominance the offspring* dominant traits exhibit themselves CO-DOMINANCE: RED RR WHITE RR
woll 4. You have been studying a trait that seems to be present in every generation within 02a particular family. Further, you have observed that every affected offspring has at won least affected parent in any particular generation. bas berswo woll Yang morto vas of oftiziqe om sno vas al Solowoh sdi lozinoo tensy vnam This trait is more likely due to a dominant or recessive allele? a) b) Interestingly, this allele is completely penetrant in the homozygous state while only 75% penetrant in the heterozygous condition. If two heterozygous individuals who carry this allele are mated, what is the expected proportion of affected progeny?
If I were working with the fruit fly Drosophilaand want to determine whether a newly found characteristic is dominant or recessive. What experiment will help me determine the dominance of the trait.
Polydactyly is an inherited trait that results in extra fingers or toes. In the United States 0.1% of the population exhibits polydactyly. People with polydactyly have the genotype Pp, where P represents the allele that causes polydactyly and p represents the normal allele of this gene. Which of the following is true? O There is not enough information to answer this question O The P allele is more frequent in the US than the p allele The two alleles, P and p are at approximately equal frequencies in the US population O The P allele is less frequent in the US than the p allele
Which one of the following options most accurately describes the process that generates the signature of a selective sweep in DNA sequence data? suppression of mutation over a long haplotype centered on a positively selected allele genetic hitchhiking of neutral alleles flanking the favored allele at the nucleotide site under positive selection O higher than average recombination around the core allele under positive selection
Traits are are controlled by a single gene, such as corn color, can be used fo predictability of trait in inheritance in humans also. This is especially import for parents who may carry alleles that code for diseases. Parents can predic probabilities that their child might inherit a disease if they know their own genotype. Parents that are carriers (heterozygous) may not show disease, bu can still pass on a disease allele. Read the scenario below (in bold). Using a separate piece of paper and draw out a Punnett square, with required information (questions 1-5). The letter D will be used to represent the domina (healthy) allele. Tom and his wife Julie are both carriers for cystic fibrosis, an autosomal recessive disease. Draw a Punnett square and be sure to include the following information for full credit: 1. Place the parents alleles at the top and on the left side. 2. Write in the allele crosses inside the Punnett squares. 3. Write out the genotypes probabilities for an offspring. 4.…
