Biology Question: "In humans, widow's peak is dominant to a straight hairline, and free earlobes are dominant to attached earlobes. A couple who is heterozygous for both traits has kids. What is the probability that the first child will have a widow's peak hairline and attached earlobes?" Answer Choice Options: A - 1/16 B - 9/16 C - 1/4 D - 3/16
Hello, please answer the following Biology question correctly based on the given answer choices. Please pick the correct "answer-letter"> Please just give the correct answer, I don't need an explanation. Thanks. Biology Question: "Based on the attached pedigree traces the appearance of a trait through a family. How is this trait inherited?" Answer Choice Options: A - through a recessive allele on the X chromosome B - through a recessive allele on an autosome C - through a dominant allele on an autosome
The diagrams represent two human somatic cells, one from a female and one from a male, and the letters in the cells represent alleles for two different traits. Male Female B = Brown hair (dominant) b = Blond hair (recessive) E = Brown eyes (dominant) e = Blue eyes (recessive) According to Mendel’s Law of Independent Assortment, what are the allele combinations expected in each of the sperm cells and what combinations are expected in each of the eggs produced by these cells during meiosis? One sperm fertilized one egg, and the resulting child has blond hair and brown eyes. How is this possible given the parents' genotypes?
What is the predicted phenotypic ratio for the offspring of the following cross? Allele phenotypes: R = red, r = white, T = thin leaf, t = broad leaf Cross: RR; Tt x Rr; tt Red with thin leaves ___________ Red with broad leaves ___________ White with thin leaves ___________ White with broad leaves __________ PLEASE show work and give an explanation... Thank you!
A type of red-green colorblindness is inherited recessively on the X chromosome. A woman who is a carrier had children with a male that is not affected by the disease. Show your answers with the use of a Punnett square • What is the probability (% or likelihood) that a child is affected by the disease? • What is the probability (% or likelihood) that a son is a carrier? (Careful!) • Is there a chance that a girl of the couple is affected by the disease?
Hi, I'm having trouble with my study guide for my upcoming genetics exam. If someone could please help with work shown and an explanation it would help so much! Thank you!! 2a. The pedigree below represents inheritance of rare condition. What pattern of inheritance is most consistent with the data? Assign alleles to all individuals to support your answer. If an allele is unknown, assign it a ? symbol. NOTE: Individuals whose phenotype or genotype cannot be determined are assumed to be unaffected and homozygous, unless otherwise indicated. 2b. In addition to the alleles you’ve indicated, describe 2 overall features of the pedigree that make it consistent with your chosen form of inheritance. 2c. Based on your mode of inheritance, what is the probability that the child of couple IV-4 x IV-5 will be affected? Show your work. attached is the pedigree
Consider the Mendelian inherited genes below (complete dominance.) Draw your answer on paper and upload a photo here or complete your answer digitally and upload your file in a common format here. A. Track one gene: Blue bonnet flower color. Dominant allele = blue flowers, B; Recessive allele = white flowers, b Cross: heterozygous plant x homozygous recessive plant Set up and draw the Punnett square for this cross Predict % likelihood of offspring possible genotype & phenotypes B. Track two genes: Bluebonnet flower color and plant height Flower color: blue dominant B, white recessive b Plant height: tall dominant T, short recessive t Cross: heterozygous plant x homozygous recessive plant Set up and draw Punnett square Predict % likelihood of offspring genotypes and phenotypes
Answer the following The next three questions go together. You cross two individuals with genotypes AaBbCcdd and AaBbccDd. What is the likelihood one of their offspring will show the recessive phenotype at exactly three of the four traits ? What are the full, four -locus target genotypes for an offspring with the recessive phenotype at exactly three of the four traits? (Feel free to use the shorthand of A - ,B - , etc. for dominant genotypes .) HINT : There are four target genotypes ; you should list all four What are the individual likelihoods of the four-locus target genotypes you identified in the last question? Make it clear what likelihood corresponds to what target genotype . What is overall likelihood of an offspring having exactly three recessive phenotypes ?
hello, please answer the following Biology correctly. I don't need an explanation, just the correct answer choices. Thank you. Bio Question: "In cats, yellow color is due to one allele, and black color is due to another allele. The heterozygous condition results in a color known as tortoise shell, with both alleles expressed. This gene is on the X chromosome. Which is an expected result of a cross between a yellow male and a tortoise-shell female? Mark all answers that apply." A - 25% of offspring will be black males B - 50% of the offspring will be yellow C- 25% of offspring will be black females D- 50% of the males will be tortoise-shell
Please explain why sex linked recessive traits are inherited by the son from his mother. If a mother is a carrier, what percentage of her sons will have the trait? Please give me example of sex linked recessive trait.
This is a modified question from the textbook, Campbell Biology in Focus (3rd edition), question #5 on page 256. A man with normal vision marries a woman with normal vision whose father was red-green color-blind (a recessive, sex-linked condition). Assuming that the woman's mother had normal vision and did not carry the recessive gene, what is the probability that the married couple will have a color-blind daughter? That their first son will be color-blind? That their second son will be color-blind? Include Punnett square for each question in your answer. You may find the below diagram helpful (the orange square means the individual has the phenotype of color-blindness, while the beige means the individual is a carrier of the mutated color-blind gene where XN and Xn represent dominant and recessive allele, respectively).
The next four questions go together. Cystic fibrosis (f) and deafness (d) are caused by two unlinked autosomal recessive alleles, and colorblindness is caused by an X-linked recessive allele Xc. A female who is deaf and is a carrier for cystic fibrosis and colorblindness marries a male who is colorblind and is a carrier for cystic fibrosis and deafness. I. What are the female's and male's genotypes? II) What is the probability their first child is a phenotypically normal female? Enter your answer as percent without the percent sign to two digits (e.g. 12.34). III) What is the probability their first child is a phenotypically normal male? Enter your answer as percent without the percent sign to two digits (e.g. 12.34). IV) What is the probability their first child has all three conditions ? Enter your answer as percent without the percent sign to two digits (e.g. 12.34).
