Who discovered linkage?
In the early 1900s, William Bateson and R. C. Punnett were studying inheritance in the sweet pea.
What is the gender of all of the white-eyed flies?
Although the first generation of 1,237 offspring was all red-eyed but for three, white-eyed flies appeared in larger numbers in the second generation. Surprisingly, all white-eyed flies were male.
Why did Hunt Morgan use fruit flies?
Morgan decided to use fruit flies to study how physical traits (for example, eye color) were transmitted from parents to offspring, and he was able to elegantly show that genes are stored in chromosomes and form the basis of heredity.
What is the importance of using fruit flies in genetics?
Fruit flies have a very simple genetic structure, which makes them ideal for genetic research. It is useful to study mutant fruit flies, as their quick reproduction rate allows scientists to observe the advantages and disadvantages of certain mutations.
Why were all the white eyed flies male?
Most of the white-eyed flies were male. Morgan hypothesized that, in his breeding experiment, the first generation of flies contained males only with white eyes because the gene controlling eye color was on the X chromosome. Males displayed the white eye trait because the trait was present on their only X chromosome.
What is the probability that a female child of Charles and Marie would suffer from hemophilia?
0 percent
What is the probability of the offspring having hemophilia for the cross?
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.
What is the probability that a female offspring of the cross that is shown above?
What is the probability that a female offspring of the cross that is shown above would have a recessive allele for Duchenne muscular dystrophy disorder? 0 percent.
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.
What should Paolo conclude?
What should Paolo conclude? Inheritance alone may not account for thick leg muscles.
What was most likely an effect on society that resulted?
Effective food supply was most likely an effect on society that resulted from improvements in blood handling during World War I and World War II. Explanation: During World war one there was a large number of people who were civilians and died due to lack of the food due to lack of import of essensial substances.
What will happen when round green and wrinkled yellow peas are crossed with each other?
Answer: 1) Round yellow is a dominant trait over wrinkled green. When the given parental plants (with genotype RRYY and rryy) are crossed, they will produce RrYy (Round yellow offsprings) in the F1 generation.
What is the probability that the offspring will be wrinkled yellow?
3 in 4 probability
What is the probability that an offspring will have wrinkled yellow seeds?
50%
What is the probability that the offspring will be tall?
Explanation: The probability of an offspring in F2 generation that exhibits dominant traits for both characteristics (green pod and tall pod shape) is 9/16. The probability of one dominant and one recessive trait (either greed pod color and short OR yellow pod and tall) is 3/16.
What is a one trait cross?
A monohybrid cross is a breeding experiment between P generation (parental generation) organisms that differ in a single given trait. Male and female gametes, produced by meiosis, have a single allele for each trait.
