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.
Explain the evolutionary significance of different modes of inheritance; for example an autosomal dominant allele which is lethal will not be passed on to future generations. Define and explain epistasis and epigenetic. Explain some things that relate genetic testin...
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...
How did Mendel determine if an allele was a dominant or recessive gene? When using a Punnett square to predict offspring ratios, we assume that a. each gamete contains one allele of each gene. b. the gametes have all possible combinations of alleles. c. male and female gametes combine at...
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...
Suppose that in the cross with the peas, you represent the dominant allele by A and the recessive allele by a. Remember that, since genes come in pairs, there are always two symbols in a genotype: AA, Aa or aa. What are the possible genotypes for a ...
