fill the 3 possible genetic combinations an organism can have
- Homozygous Dominant
- Homozygous recessive
- Heterozygous
Step by step
Solved in 2 steps
- Considering a common autosomal recessive trait: (Read each statement carefully. Select all of the statements below that are true (that you agree with). Leave any statements that are false (that you do not agree with) un- selected.) the unaffected biological siblings of an affected person should be heterozygotes. an unaffected woman and an affected man have at most a 100% probability of having a affected child. an affected person should have an affected parent. The unaffected offspring of an affected parent must be carriers.Pisssssssss helppppppppp, I’m sorry I know this is kind of a lot. How can NF1 be spontaneous? Include the following terms: -genotype - phenotype - homozygous - heterozygous - inheritance - alleles - dominant - recessiveA 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?
- Suppose "A" is a dominant gene and "a" is the corresponding recessive gene. One parent is heterozygous for the trait and the other is homozygous recessive. If they have a lot of children, which of the following is most likely? O Half are likely to be Aa, half aa O All kids will likely be AA O All kids will likely be aa O Three-fourths are likely to to be Aa, one-fourth aa O One-fourth will likely be AA, one fourth aa, and one half AaPart B 1. For the remaining characteristics, you will be looking at homozygous and heterozygous traits. Each trait will be determined to be homozygous recessive, homozygous dominant, or hetero- zygous. Letters representing the alleles will be given to you; the uppercase letter is always dominant and the lowercase letter is always recessive. If both dice rolled are even numbers, it indicates homozygous dominant alleles; if both are odd, it indicates homozygous recessive alleles; if one is odd and the other even, it indicates heterozygous alleles. 2. Eyebrows: Use the alleles "A" and "a" for this trait. Two separate brows are the dominant trait, whereas the unibrow (or one continuous brow) is recessive. 3. Eye shape: Use the alleles "R" and "r" for this trait. Round eyes are the dominant trait; almond shaped eyes are recessive. 4. Hitchhiker's thumb: Use the alleles "H" and "h" for this trait. Straight thumbs are dominant; Hitchhiker's thumbs (the curving upward of the thumb) are…In humans, Cystic Fibrosis an autosomal recessive trait, currently with medicine advances people affected by this disease can live until the 40s and 50s even. A couple in which the mother is a known carrier for this disease plans to have 4 children with a man who is not affected either but had his father who had the disease. A) Please state the genotypes of the parents. Use C to denote the dominant allele and c as the recessive B) Determine the probability that the first 2 children born have Cystic Fibrosis and the 2 last children are not affected. C) In general, what proportion of the children are expected to be female carriers of Cystic Fibrosis trait?
- Achondroplasia is the most common form of dwarfism in miniature horses. Achondroplasia dwarf horses have normal sized bodies and heads, but noticeably smaller upper legs and ears. This form of dwarfism is an autosomal dominant trait. The pedigree shows the offspring of one horse without dwarfism, Individual 1, and one with dwarfism, Individual 2. The horses with achondroplasia are shorter. 1 2YOUR SISTER DIED FROM TAY-SACHS DISEASE, INHERITED AS A RECESSIVE ALLELE (t). you're married and planning to start your family. you're worried about the disease and decide to have genetic testing to see if you or your spouse is a carrier of the tay-sachs allele. the test results show that you're a carrier of the allele, but your spouse isn't. what is the probability that you and your spouse will have a child with tay-sachs disease? show your work.YOUluue Non-Mendelian genetic inheritance-any pattern of inheritance in which Mendelian Genetics Non-Mendelian Genetics -Patterns of inheritance in which traits are not -The way in which genes and their corresponding traits are passed from -The two alleles of a gene are either -The two alleles of a gene are neither -Phenotypic outcomes can be -Phenotypic outcomes can be -Examples include -Examples include Created By: Chivas & Jordan Spivey
- PRISCILLA TORRES Mendelian Genetics [6F.R]:Question 2 In fruit flies, red eyes (R) are a dominant trait and white eyes (r) are recessive. If a homozygous red eyed fly was crossed with a white eyed fly, what percent of the offspring would be homozygous recessive? Select one: 50% 100% 25% DELIEach box represents a potential offspring. Notice that genotypically speaking, they are all the same. Theyare all heterozygous (genotype) which means their phenotype is dark coloration. So, there is 100% chanceof producing a dark eyed, heterozygous offspring. What if that offspring mated with a light eyedindividual? Can you make a Punnett Square for that?Write the Genotypes and Phenotypes of the parents on the left of the square. Complete the square, thenwrite the potential offspring’s genotypes and phenotypes on the right of the square. Parents: Offspring:Genotypes: phenotypes: What are the genotypes of the resulting offspring? What are the phenotypes of the resulting offspring?Forms and Expressions of Alleles Classify each of the following phenotypes and genotypes using the vocabulary from this lesson.
