A scientist is investigating the possibility that two traits in a particular plant are determined by genes that are on the same chromosome. The scientist crossed a plant that is homozygous dominant for both traits with a plant that is homozygous recessive for both traits. The heterozygous offspring in the Fl generation were then crossed with a plant that is homozygous recessive for both traits. The results expected if the genes independently assort and the observed results are presented in the table. Phenotype Expected Number in F2 Observed Number in F2 25 17 Long stems, white flowers Short stems, red flowers 25 19 Long stems, red flowers 25 31 25 33 Short stems, white flowers Total number of plants 100 100 Which of the following critical values should the scientist use for the chi-square analysis of the data? a. 3.00 b. 3.84 c. 7.81 d. 8.00

Answers

Answer 1

The critical value the scientist should use for the chi-square analysis of the data is b. 3.84.

THE CHI-SQUARE ANALYSIS OF THE DATA

The chi-square test is a statistical test used to determine whether there is a significant difference between the observed and expected frequencies in a contingency table. In this case, the scientist is investigating whether two traits in a plant, long stems and white flowers, are determined by genes that are on the same chromosome. The scientist has conducted a genetic cross between plants that are homozygous dominant and homozygous recessive for both traits, and has obtained a sample of 100 plants in the F2 generation. The scientist has then tabulated the observed and expected frequencies of the four possible phenotypes (long stems, white flowers; short stems, red flowers; long stems, red flowers; short stems, white flowers) in the F2 generation.

The chi-square test is used to determine whether there is a significant difference between the observed and expected frequencies in the table. The calculated chi-square value is compared to a critical value from a chi-square distribution table with 3 degrees of freedom and a significance level of 0.05. The degrees of freedom for a chi-square test are equal to the number of categories in the table minus 1. In this case, there are 4 categories (phenotypes) in the table, so the degrees of freedom are 3.

The critical value for this test is 3.84. If the calculated chi-square value is less than 3.84, the scientist would conclude that there is no significant difference between the observed and expected frequencies and thus the genes independently assort, meaning that the genes are located on different chromosomes. On the other hand, if the calculated chi-square value is greater than 3.84, the scientist would conclude that there is a significant difference between the observed and expected frequencies and thus the genes are located on the same chromosome.

How do you calculate pedigree risk?

Answers

Pedigree risk calculation: A heterozygote has a 50% chance of not passing the a gene to their progeny. The likelihood that she won't pass it on to one of her two children is (1/2)(1/2) = 0.5 2 = 1/4.

By analysing a pedigree, we may identify genotypes, recognise phenotypes, and predict how a trait will be passed down in the future. A pedigree's information can be used to assess an allele's mode of inheritance, such as whether it is dominant, recessive, autosomal, or sex-linked.

Analyze the trait's dominance or recessivity. The trait must be possessed by one of the parents in order to be dominant. No generation will be exempt from prevailing traits. As long as both parents are heterozygous, a recessive characteristic can exist even if neither parent possesses it.

If the trait is autosomal or sex-linked, analyse the graph to find out (often X-linked). For instance, in X-linked recessive traits, males are noticeably more likely to be affected than females. Autosomal traits have an equal chance of affecting males and girls (usually in equal proportions).

b. 50% chance of yellow skin
c. 75% chance of yellow skin
d. it is not possible for their offspring to have yellow skin because Patterson has the dominant trait

Answers

Answer:

b. 50% chance of yellow skin

Explanation:

The likelihood that their kid will have yellow skin depends on the genetic makeup of both Patterson and Petunia. Patterson has the genotype Pp, which means he has one dominant allele for pink body color and one recessive allele for yellow body color. Petunia, on the other hand, has the genotype pp, which means she is homozygous recessive for yellow body color.

When they have children, each parent will contribute one of their alleles to their offspring. The offspring will have a 50% chance of inheriting the recessive allele for yellow body color from Patterson and a 50% chance of inheriting the recessive allele for yellow body color from Petunia. Therefore, the likelihood that their kid will have yellow skin is 50%.

a. All of their sons and half of their daughters could have DMD.
b. Half of their sons and half of their daughters could have DMD.
c.Half of their sons and none of their daughters could have DMD.
d. None of their sons and half of their daughters could have DMD.

Answers

Answer:

C. Half of their sons and none of their daughters could have DMD.

Explanation:

DMD is a recessive disorder carried on the X chromosome and it is sex-linked. This means that the gene for DMD is located on the X chromosome and it affects mostly males.

If a woman is a carrier of DMD, it means that she has one copy of the mutated gene and one normal copy, and she does not show any symptoms of the disorder.

If a man without the disorder has children with this carrier woman, half of their sons will inherit the mutated X chromosome from the mother. Therefore, they will have the disorder and half of their sons could have DMD.

Since, Females have two X chromosomes, and therefore, if a daughter inherits the mutated X chromosome from the mother, the second X chromosome will be normal which will help in compensating the effects of the mutant one, hence they will be carrier of the disorder but will not show any symptoms. So none of their daughters could have DMD.

So, the outcome is: C. Half of their sons and none of their daughters could have DMD.

Answer:D

Explanation:

I think it is D because only the mother had it and not the father. I don't think the father could get DMD through sex either. So I think that none of their sons and half the daughters could have DMD because they inherited it from the mother.
