Note that your Punnett Squares predictions assumed the law of independent assortment was true for these characteristics . How do the percentages of purple smooth , purple wrinkled , yellow smooth , and yellow wrinkled kernels on the cob ( # 9 ) compare to those predicted in # 8 ? Given these results , do the alleles for corn kernel color and shape segregate independently or are they linked ?
Do a chi square tablet for the question. I left a reference down below. Question: 3. In dihybrid cross where both parents were heterozygous for both traits, the following data was obtained: 890 dominant for both traits, 97 recessive for both traits, 315 dominant for trait 1, but recessive for trait 2, and 298 dominant for trait 2, but recessive for trait one. Perform a chi-square analysis to determine if this data agrees with the expected outcomes. State your null hypothesis as well as if the null is rejected or not.
Orchids come in an amazing variety of colours. Scientists found that cloned Cattleya orchids have a phenotypic variance of 14, while wild Cattleya orchids have a phenotypic variance of 29. What is the broad-sense heritability of these orchids?
next several questions all refer to the following problem. In dragons, the following are simple, autosomal Mendelian traits: Forelimbs (f+) is dominant to no forelimbs (f-) Wings (w+) is dominant to no wings (W-) Horns (h+) is dominant to no horns (h-) You cross a dragon from a true-breeding line with forelimbs, wings, and horns, to a dragon from another true-breeding line with no forelimbs, no wings, and no horns. You then test-cross an F1 dragon to one with no forelimbs, no wings, and no horns. You obtain the following numbers of offspring: 622 forelimbs, wings, horns 630 no forelimbs, no wings, no horns 55 forelimbs, no wings, no horns 62 no forelimbs, wings, horns 104 forelimbs, no wings, horns 109 no forelimbs, wings, no horns 3 forelimbs, wings, no horns 6 no forelimbs, no wings, horns Which gene is in the middle? 1.) Forelimbs (f) 2.) Wings (w) 3.) Horns (h)

A danger in computing heritability values from studiesinvolving genetically related individuals is the possibility that theseindividuals share more similar environments than do unrelatedindividuals. In the experiment shown in Figure 24.8, which dataare the most compelling evidence that ridge count is not causedby genetically related individuals sharing common environments?Explain
Genetic cross with independent assortment (unlinked traits). Wolves are sometimes observed to have black coats and blue eyes. Assume that these traits are each determined by single genes that are located on different Also assume that normal gray coat color (G) is dominant to black (g) and brown eyes (B) are dominant to blue (b). Suppose that each parent has a normal-colored coat and brown eyes, and that both individuals are heterozygous for both traits. Use the Punnett Square below to answer the following questions: GgBb x GgBb GB Gb gB gb GB GGBB GGBb GgBB GgBb Gb GGBb GGbb GgBb Ggbb gB GgBB GgBb ggBB ggBb gb GgBb Ggbb ggBb ggbb a) From your Punnett square, how many individuals are dihybrids? b) How many individuals are both homozygous recessive for coat color and heterozygous for eye color (ggBb)? c) Fill in the blanks to state the expected phenotypic ratio of the offspring:…
8 Rosettes are the dominant coat type (R) in guinea pigs while smooth coat is recessive (r). Of 1630 guinea pigs observed on an expedition in South America, 1190 have rosettes and 440 present with a smooth coat. a. If this muddle of guinea pigs is in Hardy-Weinberg equilibrium for the hair coat locus, what is the frequency of the recessive allele?
Mid-Digital Hair and FrecklesFinger mid-digital hair (M) is dominant over the recessive trait of no mid-digital hair (m). Freckles (F) is dominant over the recessive trait of no freckles (f). (It is important to note that this example of mid-digital hair and freckles cannot be explained with simple genetics, but for the purpose of this question, assume that it can.)A woman that is heterozygous for freckles and has no mid-digital hair is married to a man with no freckles that is heterozygous for mid-digital hair. The couple is expecting a child. Draw a Punnett square of this cross then answer the following questions: What is the probability that their offspring will have mid-digital hair? What is the probability that two offspring in a row will have no freckles? What is the probability of two offspring in a row having mid-digital hair and freckles?
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).
In a herd of dairy cattle, milk yield and the percentage of butterfat exhibit a geneticcorrelation of −0.38. If greater milk yield is selected in this herd, what will be the effecton the percentage of butterfat?
In humans, widow's peak (H) is dominant over a continuous hairline (h), and short fingers (F) are dominant over long fingers (f). Two heterozygous individuals with widow's peak and short fingers want to have a child with continuous hairline and long fingers. Is this possible?
