If a woman who is heterozygous for blood type A marries a man that is blood type O, what is the probability that they will produce a child with blood type O? Two parents with blood types A and O have a child who has type O blood....
An organism that has the same two copies of a gene is consideredhomozygousfor that trait, while an organism that has different copies of a gene for a particular trait is consideredheterozygousfor that trait. In plant and animal breeding, such organisms can be calledhomozygotesandheterozygotes. W...
What is an Heterozygous Organism? What are Chromosomes? Discussion Comments Bymatthewc23— On Jun 29, 2011 @cardsfan27 - You can predict what traits a child will have assuming both of the parts are homozygous recessive. This would mean that no matter what combination gets sent to the next ...
What is the characteristic phenotypic ratio of a dihybrid punnet square when you cross two heterozygous individuals? In a dihybrid cross using Mendelian inheritance, if both parents are heterozygous for both traits, what will be the phenotypic ratio of ...
unlike the parent generation. If two heterozygous offspring are then bred together, the resulting possibilities make up a monohybrid cross. Since the two parents in a second breeding would both be “Gg,” the possibilities for the coloration trait in offspring is easy to anticipate. There are fo...
What is the probability that two parents who are heterozygous for the recessive trait of albinism will have two albino offspring? (父母双方都是白化病（隐性遗传）的杂合子，其后代中有两个白化病患者的概率是多少)（ ）
same allele is homozygous. An individual who carries two different alleles for a certain gene is heterozygous. So here are some possibilities of eye colour below: A person with two blue alleles will have blue eyes. A person with two brown alleles will have brown eyes. ...
A recessive trait is one that is only expressed when an organism has two recessive alleles for that trait. They are less common than dominant traits in most populations because dominant traits will appear in those with both homozygous dominant and heterozygous alleles. What are examples of recessiv...
From a cross of a dominant true breeding strain with a dihybrid, what is the likelihood of getting an offspring with one locus heterozygous and the other homozygous? If two parents with genotypes AABbCc for the mom and AaBbCc for the dad were ...
ThePunnett squarepredicts allelic pairs of offspring. For instance, the predictedgenotypeof children born to two parents with heterozygous alleles is often shown in a chart. The dominance and recessive traits chart indicates a 1:2:1 ratio with 50 percent of the offspring having heterozygous allele...
