Most genes have a small effect on character state expression O b. Alleles have an additive effect on the character state expressed c. Substituting an allele in a genotype may significantly affect the expressed phenotype O d. Phenotypes are affected by environments. O e. Phenotypic characters are distributed continuously.

In 1927, the ophthalmologist George Waaler tested9049 schoolboys in Oslo, Norway, for red-green colorblindness and found 8324 of them to be normal and725 to be color blind. He also tested 9072 schoolgirlsand found 9032 that had normal color vision while40 were color blind.a. Assuming that the same sex-linked recessive allelec causes all forms of red-green color blindness,calculate the allele frequencies of c and C (the allelefor normal vision) from the data for the schoolboys.(Hint: Refer to your answer to Problem 12a.)b. Does Waaler’s sample demonstrate Hardy-Weinbergequilibrium for alleles of this gene? Explain youranswer by describing observations that are eitherconsistent or inconsistent with this hypothesis.On closer analysis of these schoolchildren, Waalerfound that there was actually more than one c allelecausing color blindness in his sample: one kind forthe prot type (cp) and one for the deuter type (cd).(Protanopia and deuteranopia are slightly differentforms of red-green…
.A) To determine if a human trait is heritable, we would best study Group of answer choices. I think it's A. Please explain your answer I'm trying to understand the material a. monozygotic twins that were raised separately, in different environments. b. monozygotic twins that have been raised under similar conditions. c.only distantly related individuals. d. all males or all females. B). To say that a trait exhibits “high heritability” is to say that a. a given set of genes has no influence on a trait. b. there is no difference in genotype between members of the population at the loci in question. c. in a given environment and population, genetic differences have a high degree of influence on the trait compared to environmental influences. d. there is no difference in character between two individuals with the same genotype in question. C). If two populations with identical genetic makeup are raised in different environments, the narrow-sense heritability of a trait of…
n each case where Mendel crossed (i.e., mated) two different true-breeding plants as parents, the offspring displayed only one of the two traits seen in the parents. For instance, a cross between a true-breeding “tall” plant and a true-breeding “short” plant produced offspring that were all “tall.” This observation supports which principle of genetics? a. The law of segregation b. The law of independent assortment c. Dominance and recessiveness d. Allele anomaly e. Gene linkage
Using the HardyWeinberg Law in Human Genetics In a given population, the frequencies of the four phenotypic classes of the ABO blood groups are found to be A = 0.33, B = 0.33, AB = 0.18, and i = 0.16. What is the frequency of the i allele?
In sweet pea plant, an allele for purple flowers (P) is dominant when paired with a recessive allele for red flowers (p). An allele for long pollen grains (L) is dominant when paired with a recessive allele for round pollen grain (l). Bateson and Punnett crossed a plant having purple flowers/long pollen grains with one having white/flowers/round pollen grains. All F1 offspring had purple flowers and long pollen grains. Among the F2 generation, the researchers observed the following phenotypes: 296 purple flowers/long pollen grains 19 purple flowers/round pollen grains 27 red flowers/long pollen grains 85 red flowers/round pollen grains What is the best explanation for these results?
Two pairs of genes (TTLL) are postulated to influence the size of corn in certain varieties with equal and additive effects. A tall corn variety averaging 6 feet was crossed with a dwarf corn variety averaging 2 feet. (a) If the size of the dwarf is attributed to the genotype (ttll), what is the effect of each gene that increases the size above 2 feet? (b) Diagram a cross between a large and small variety, and classify the expected F2 phenotypes.
Polymorphism of body color is caused by two alleles in a fly. One allele's homozygotes are brown, other homozygotes allele are pale, whereas heterozygotes have orange color. This is the observation made by the experimenters: brown: 100 pale: 100 orange: 50 find the genotype frequncy under hardy-weinberg equil. and then show the calcultaions to find the coefficient of inbredding for this locus.
In Ayrshire cattle, the spotting of the coat can be either red andwhite or mahogany and white. The mahogany-and-white phenotypeis caused by the allele SM (where the letter S indicates spotting, andthe superscript M stands for mahogany). The red-and-white phenotypeis controlled by the allele SR (where the superscript R standsfor red). The table below shows the relationships between genotypeand phenotype for males and females: Explain the pattern of inheritance.

In roan bulls, alleles for both red and white hair are codominant (BRBW). What is the percentage of genotype and phenotype if a roan cattle is bred to, (a) a homozygous red cow (BRBR), (b) a heterozygous white cow (BWBw).
Doing genetic analysis it is determined that two parents are heterozygous for two separate unlinked recessive traits (i.e., both parents are heterozygous for both loci). Given this genetic information, what is the probability of their having a child which is homozygous recessive for both traits?
