A dominant allele is an allele that generates a compound X that has an impact Y on the functioning or structure of the organisms and that generates...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our expe...
The basis of his discoveries was that offspring receive one allele for each gene from each parent. The way that these genes interact vary, but the most common is dominant versus recessive, where the dominant allele will show its phenotype regardless of the other allele, while the recessive ...
in autosomal-dominant conditions, the offspring only needs one parent to pass down an abnormal gene for their health to be affected. Again, the gene in question lies on a non-sex chromosome.
Reginald Punnett, an English geneticist, developed the Punnett square to determine the potential genetic outcomes from a cross. Merriam-Webster says its first known use occurred in 1942. Heterozygous plants have a dominant and a recessive allele (alternate form) for a given trait. The Punnett squa...
The convention is to always write the capital dominant allele first followed by the lowercase recessive allele. For our hair color example two brown-haired parents could either be BB or Bb. You would have to know their specific genotype. However, if the parent is blonde you know their genotyp...
(Hint: This is too complicated to do with a Punnett square. Use the rules of multiplication for this problem.) a. 1/16 b. 1/64 c. How did Mendel determine if an allele was a dominant or recessive gene? Give the predicted genotypes for F2-generation for the dihybrid cross in the ...
How do alleles determine the expression of traits? How many genes do you inherit from grandparents? What is not an autosomal recessive trait? What is the difference between a dominant allele and a recessive allele? What are lethal alleles in the gene pool? What is the difference between a ge...
A necessary term to understand before approaching this problem is dihybrid. A dihybrid is an individual who is heterozygous for two different traits of interest. For example, if we are interested in hair color, which we'll assign H and h for the dominant dark hair and recessive light hai...
Choose a trait that has a genetic component (example: eye color, hair color) and discuss how this trait is passed down from generation to generation (dominant/recessive etc.). Write an original response of 150 words. Color vision is due to the: a. cones. b. rods. The Rh factor is in...
In genetics, there is a dominant allele and a recessive allele. A codominance occurs when a certain genotype contains a dominant allele and a...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your tough ...
