The answer is 1/2 x 0.50 because If both parents have sickle cell trait ,there is 25% chance that the foetus will suffer from sickle cell anemia.
So ,
1/2 x 0.50 =0.25
ie, 25%

MN blood type in humans is determined by two alleles at a single
co-dominant locus; these alleles are LM and
LN. In a sample of 1190 individuals , it was found
that:
75 had type M blood (LMLM)
800 had type MN blood (LMLN)
315 had type N blood (LNLN)
Given this population data, calculate the observed
allele frequencies and the expected number of individuals
of each genotype. For allele frequency reposes, please round to 3
decimal places (ex. 0.000)....

8) There is a blood type gene with three alleles A, B and O. A is dominant to O, B is dominant to O and A and B are co-dominant/incompletely dominant. What are the likely genotypes if a mother has the genotype AA and the father has the genotype BO? Group of answer choices a) 50% AA 50% BB b) 50% Ab blood 50% A blood c) 25% AB, 25% AO, 50% OO d) 50% AB 50% AO 9) There is...

LOUISE Homework Quizzes & Tests A gene is composed of two alleles. An allele can be either dominant or recessive. Suppose that a rusband di wile, allele but do not have the disease, decide to have a child. Because both parents are carriers of the disease, each has one dominant normal-cell allele (S) and one recessive sickle-cell allele (s). Therefore, the genotype of each parent is Ss. Each parent contributes one allele to his or her offspring with each allele...

6. Sickle cell anemia (disease) is described as an autosomal recessive condition (individuals must have two copies of the recessive allele to display “sickle cell disease”). However, sickle cell trait (the heterozygous condition) has a unique phenotype. a. How would you classify/describe sickle cell trait at the organismal level (complete, incomplete, or co-dominance)? Explain your reasoning. b. How would you classify/describe sickle cell trait at the molecular level (complete, incomplete, or co-dominance)? Explain your reasoning. (HINT: think about the hemoglobin...

Question 2: In an outbreeding diploid population, an autosomal locus has two alleles, A1 and A2. You observe the allele frequencies of A1 and A2 are both equal to 0.5, and the relative fitnesses of the three genotypes (A1A1, A1A2, and A2A2) are equal to 2, 1.5, and 1, respectively. A) Which allele will become fixed in this population? (1 point) **The recessive beneficial allele A2A2 will eventually become fixed in the population (A2A2=1) B) What is the allele frequency...

AL11 Activity 4: Multiple alleles with Codominance 1. Some traits in a population are determined by multiple alleles. For example, there are three alleles for Mood type in the human population (type A), P type B). and i lypeo). Different combinations of these alleles (each individual can inherit only two alleles) produce the four different blood types (phenotypes) that we are familiar with Based upon the symbols alone, what can you predict about the relationships between each of the following...

Although the following scenario is hypothetical, it is based on actual facts. Sickle cell anemia is an inherited form of anemia. Those with sickle cell anemia do not have enough healthy red blood cells to adequately carry oxygen to all the cells in their body. Normal red blood cells are flexible and round, and can easily move through the blood vessels. However, in...
