C is correct answer.
Crossing over takes place at the ends of chromosome.
Single cross over swaps small segment of the chromosome.
QUESTION 14 For a heterozygote, five genes are arranged in this order on its chromosomes: a—...
19. A viable inversion heterozygote is undergoing meiosis. The chromosomes are illustrated below. Compare the consequences of crossing over in two cases: crossing over between C and D, and crossing over between F and G ABCDEFGHIJK 2 ABCHG FEDIJK 20. Using the same inverted chromosome above: a. Two crossing over events occur among these chromatids: a crossover between genes H and G on chromatids 2 and 4, and a crossover between genes D and E on chromatids 1 and 3....
1. An inversion heterozygote has the following inverted chromosome: ABCD JIHGF.EKLM. a. Sketch how this chromosome will pair with its normal homologue (AB CDE FGHIJ K L M) in prophase I. Make sure you include all strands (remember, the chromosomes are replicated). (2 pts) b. What four gametes result when a single crossover occurs between genes F and G on one inversion and one normal chromosome? (4 pts)
Which of the following statements regarding genes is false? a) Genes are located on chromosomes b) Genes consist of a long sequence of DNA c) In sexually reproducing species each cell contains a single copy of every gene d) Genes contain information for the production of a single protein e) none of the above
The figure shows the cross-shaped chromosome pairing that forms during meiosis in a translocation heterozygote. The diagram shows two pairs of homologous chromosomes. Chromosome 1 is red and normally has genes A, B, C, D, E, and F. Chromosome 2 is blue and normally has genes P, Q, R, S, T, and U. The chromosomes labeled Mand N2 have the normal complement of genes in the correct order. The chromosomes labeled 71 and 72 have a reciprocal translocation. Complete the...
13. Creighton and McClintock worked with homologous chromosomes physically exchange genetic information during crossing over and their model system to show that A) Peas B. Corn 14. While mapping two genes in Drosophila you observe 40 recombinants among 200 total A) 30 map units 15. Another name for a chromosome is C. Fruit flies D. Tobacco offspring. What is the distance between these genes? B. 20 map units C200 map units D. 6.67 map units , since it contains genes...
in a reciprocal translocation heterozygote, which of the following are true? You can choose multiple options. Select one or more: a. The individual with a reciprocal translocation will not produce fertile gametes. b. In a reciprocal translocation heterozygote about 1/3 of their gametes are likely to be non-viable. c. A reciprocal translocation does not cause phenotypic effects. d. In a reciprocal translocation heterozygote about 1/2 of their gametes are likely to be non-viable. e In a reciprocal translocation heterozygote some...
In a reciprocal translocation heterozygote, which of the following are true? You can choose multiple options. Select one or more: a. The individual with a reciprocal translocation will not produce fertile gametes. b. In a reciprocal translocation heterozygote some genes are missing and some genes are duplicated. c. A reciprocal translocation does not cause phenotypic effects. d. In a reciprocal translocation heterozygote there is the same amount of genetic information (same number of gene copies) as in a diploid individual...
A Haploid yeast strain that is deficient in its ability to make arginine, is crossed to a different haploid yeast strain also unable to produce arginine. The resulting diploid, F1 strain is able to make its own arginine. What is the best explanation? Each deficient haploid strain possessed a mutant allele, but not in the same gene, thus the diploid had 1 functional copy of each gene The defective arginine biosynthetic enzymes, made from the mutant genes, were able to...
Which of the following is the Law of Dominance? A. in a heterozygote, the two different alleles are equally expressed B. in the heterozygote, one allele will mask the expression of the other C. In the production of gametes, gene pairs behave independently of other gene pairs D. In the production of gametes, a gene pair separates so each gamete gets one gene from the pair E. the outward expression of a genetic trait is controlled by a pair of...
genetics problem. need help with both questions and drawings are helpful. thank u. Question 11) (7 points) Consider 10 genes on different chromosomes in a diploid organism. An individual is homozygous for 6 genes and heterozygous for 4 genes. Among a large population of gametes from that individual, how many different genotypes do you predict would be present? Question 12) (6 points) There are several genes in humans in addition to the I gene (for ABO blood group) that generate...
