Can females get X-linked recessive diseases?
Females can get an X-linked recessive disorder, but this is very rare. An abnormal gene on the X chromosome from each parent would be required, since a female has two X chromosomes.
What is the probability that a female child of Charles and Marie would suffer from hemophilia?
What is the probability that a female child of Charles and Marie would suffer from hemophilia? 0 percent.
How can a female carrier of an X-linked recessive disorder have a daughter who is affected?
With each pregnancy, a woman who carries an X-linked recessive disorder has a 50 percent chance of having sons who are affected and a 50 percent chance of having daughters who carry one copy of the mutated gene.
What is the probability of the offspring having hemophilia for the cross that is shown in the Punnett square?
Explanation: A 25% (one in four) chance of having a son with hemophilia; a 25% chance of having a son with normal blood clotting; a 25% chance of having a daughter who is a carrier; a 25% chance of having a daughter who has hemophilia; This is shown in Figure 2-6.
Why must males inherit colorblindness from their mothers?
Why must males inherit colorblindness or hemophilia from their mothers? Because their mother gives them their X chromosome. Why is colorblindness or hemophilia more common in males than in females? Because the trait is recessive and since they only have one allele, there is no Other allele expressed.
What is the best evidence to prove that Irene was heterozygous for hemophilia?
The best evidence to prove that Irene was heterozygous for hemophilia would be that Alice carried the recessive allele.
Which was most likely an effect on society that resulted from improvements in blood handling during World War I and World War II more soldiers died as a result of incorrect blood typing more soldiers who had lost a limb returned home more donations were needed?
Which was most likely an effect on society that resulted from improvements in blood handling during World War I and World War II? More soldiers died as a result of incorrect blood typing. More donations were needed as a result of poor storage techniques.
Is Hemophilia dominant or recessive?
Hemophilia is a sex-linked recessive disorder. The abnormal gene responsible for hemophilia is carried on the X chromosome. Males have one X chromosome and one Y chromosome.
What will happen when round green and wrinkled yellow peas are crossed with each other?
If a round, green seeded pea plant (RR yy) is crossed with wrinkled, yellow seeded pea plant, (rr YY) the seeds production in F1 generation are. Two pea plants one with round green seeds (RRyy) and another with wrinkled yellow (YY) seeds produce F1, progeny that have round, yellow (RrYy) seeds.
What is the probability that a cross between a hybrid pea plant with round seeds and one with wrinkled seeds will produce offspring with wrinkled seeds?
What is the probability of having offspring that have wrinkled seeds and yellow seed color?
What is the predicted phenotypic ratio of the offspring Brainly?
The predicted phenotypic ratio of the offspring is 50 percent Yy and 50 percent yy. Further Explanation: Genotypes help in the genetic makeup of any individual. Phenotype describes as a physical characteristic of an individual.
Who has hemophilia in the pedigree that is shown?
Hemophilia is an X-linked recessive disorder that is passed through generations and can be traced by using a pedigree. Who has hemophilia in the pedigree that is shown? John and Ann. Fred and Luke.
Which describes an organism that has nonidentical alleles for seed color?
Which Mendel generations were allowed to self pollinate?
Mendel allowed the first-generation plants to self-pollinate. Figure 5 also shows what happened when a first-generation plant with purple flowers was allowed to self-pollinate. As you can see, the recessive trait for white flowers reappeared in the second generation.
Which is the best example of a hypothesis leading to new experimental methods?
The best example of hypothesis which leads to new experiment methods was done by Morgan where he used fruit flies. Thomas Hunt Morgan continues on genetic research which is of Gregor Mendel.
Which is the best example of a hypothesis?
Examples of Hypothesis:
- If I replace the battery in my car, then my car will get better gas mileage.
- If I eat more vegetables, then I will lose weight faster.
- If I add fertilizer to my garden, then my plants will grow faster.
- If I brush my teeth every day, then I will not develop cavities.
Why did Gregor Mendel use peas?
For Gregor Mendel, pea plants were fundamental in allowing him to understand the means by which traits are inherited between parent and offspring. He chose pea plants because they were easy to grow, could be bred rapidly, and had several observable characteristics, like petal color and pea color.
Which best describes Mendel’s work with pea plants?
Answer. Mendel worked with pea plants in his experiment. In a pea plant it contains both the female part and male part in the same flower. As a result they can do both self pollination and cross pollination in the plant.
Why was Mendel’s work not accepted at the time?
Mendel’s work was not accepted because during that time DNA had not yet been discovered. Without the discovery of DNA, there was no concrete proof that the processes Mendel described actually happened.
What statement summarizes the law of segregation?
The law of segregation states that each individual that is a diploid has a pair of alleles (copy) for a particular trait. Each parent passes an allele at random to their offspring resulting in a diploid organism. The allele that contains the dominant trait determines the phenotype of the offspring.
In which squares should the phrase green pods appear?
Green pods phrases should appear in squares A, C, and D. Explanation: Further explanation will be posted as an attachment due to technical difficulties.
What are the three Mendelian laws of inheritance?
The Mendel’s laws of inheritance include law of dominance, law of segregation and law of independent assortment.
What kind of letter is used for a dominant trait?
Is the capital letter always dominant?
Capital letters are typically used for the dominant trait, while lowercase letters are used for recessive traits. If you see a lowercase and an uppercase letter together, the uppercase letter (the dominant one) is the one that will be expressed.
What does F stand for in genotypes?
What is the physical look of a trait?
phenotype. An organism’s physical appearance, or visible traits. genotype. An organism’s genetic makeup, or allele combinations. heterozygous.
