The Genes you are examining exhibit a continuous pattern of variation. For these Genes, a Dominant Allele represents a 1 foot increase in overall height. If you cross the following individuals, AaBb and AaBb, what percentage of the offspring will be 7 feet tall. Assume an individual with no Dominant Alleles (aabb) is 4 feet tall. Report your answer as a percentage i.e., 22.1%.

SEATWORK Symbols (for pea plant traits): • T: Tall t: short Analyze the following problems. Determine the possible genotypes, genotypic ratio, phenotypes, and phenotypic ratio from the genetic cross. Show your solution through a Punnett square. Use the symbols provided. • R: Round seeds r: wrinkled seeds • Y: Yellow seeds y: green seeds • P: Purple flower p: white flower 1) Cross a homozygous dominant tall and homozygous round seed pea plant with a heterozygous tall and heterozygous round seed pea plant. 2) Cross a pea plant that is heterozygous for purple flowers and homozygous dominant for yellow seeds with a pea plant that is heterozygous for purple flowers and homozygous recessive for green seeds. 3) Cross a pea plant that is short and has green seeds with a pea plant that is heterozygous tall and has heterozygous yellow seeds.
Given the following testcross data for corn in which the genes for fine stripe (f), bronze aleurone (bz) and knotted leaf (Kn) are involved: PhenotypeNumber Kn + +451 Kn f +134 + + + 97 + f bz436 Kn + bz18 + + bz119 + f +24 Kn f bz86 Total:1,365 Maize geneticists tend to be like Drosophila geneticists utilizing a + to indicate the wild type allele (which also is dominant) and a lower case letter for the mutant allele (which is recessive). The first thing I suggest in attacking this problem is to use the typical convention of upper case letters for dominant alleles and lower case letters for recessive alleles as follows: F = wild type, f = fine stripe; B = wild type, b = bronze aleurone K = wild type, k = knotted leaf Then we can rewrite the phenotypes in a “language” that is more easily understood: PhenotypeNumber k F B451 k f B134 K F B97 K f b436 k F b18 K F b119 K f B24 k f b86 Total:1,365 a) Determine the sequence (order) of the…

The Turner Kieser Syndrome (or nail patella syndrome) is a dominant human disease (prevalence about 1/100.000), which impairs the normal development of, nails and kneecaps (patella). In the following study the mutant allele for this gene is noted "M" and the wild type allele "m". On the family tree below black symbols (circles for women and squares for men) indicate people suffering from KSS and open symbols represent healthy persons.

Basic body color for horses is influenced by several genes, one of which has several different alleles, Two of these alleles—the chestnut (dark brown) allele and a diluting (pale cream) allele (often incorrectly called ‘albino’) - display incomplete dominance. A horse heterozygous for these two alleles is a palomino (golden body color with flaxen mane and tail). Is it possible to produce a herd of pure-breeding palomino horses? Why or why not? Work test cross for mating a palomino to a palomino and predict the phenotypic ratio among their offspring
Hardy-Weinberg Problems Please be sure to SHOW ALL WORK in order to get credit. This assignment will be graded for accuracy. *Hint: Remember what p and q represent. Determine first if I am asking for allele frequency or genotype/phenotype frequency. Then determine which equation is appropriate. What does p and q represent in the equations? Which equation do you use if I am asking for allele frequency? If the frequency of the recessive allele is 0.1, what is the frequency of the dominant allele? If the frequency of the dominant allele is 0.4, what is the frequency of the recessive allele? If the frequency of the dominant allele is 0.6, what is the frequency of the homozygous dominant genotype? If the frequency of the homozygous recessive genotype is 0.81, what is the frequency of the recessive allele? If the frequency of the homozygous dominant genotype is 0.25, what is the frequency of the dominant allele? If the frequency of the…
A pedigree analysis was performed on the family of a man with schizophrenia. Based on the known concordance statistics, would his MZ twin be at high risk for the disease? Would the twins risk decrease if he were raised in an environment different from that of his schizophrenic brother?
As it turned out, one of the tallest Potsdam Guards had an unquenchable attraction to short women. During his tenure as guard, he had numerous clandestine affairs. In each case, children resulted. Subsequently, some of the childrenwho had no way of knowing that they were relatedmarried and had children of their own. Assume that two pairs of genes determine height. The genotype of the 7-foot-tall Potsdam Guard was A9A9B9B9, and the genotype of all of his 5-foot clandestine lovers was AABB. An A9 or B9 allele in the offspring each adds 6 inches to the base height of 5 feet conferred by the AABB genotype. a. What were the genotypes and phenotypes of all the F1 children? b. Diagram the cross between the F1 offspring, and give all possible genotypes and phenotypes of the F2 progeny

Connection to Quantitative traits: SNPs are inherited in a Mendelian fashion and are often polygenic in nature. We can think of SNPs in terms of either contributing or non-contributing alleles. A study of SNPs correlated with heart disease has shown that heart problems are severe if 9 or more of the alleles at 6 loci are of the contributing variety. What is the probability the following parents will have a child that is susceptible heart disease? AaBbccDDEEFf x AaBbCCDdEeff
