Question

The alleles of different loci independent assortment of these alleles can result in 80. A. non-allelic B. recombination C. allelic are assorted at random with respect to each other in the gamete and the 80 E. A and C are correct D. homologous gene that lie close to each other on the same pair of homologous chromosome and their alleles do not assorted independently are called- 81. A. homology B. chromatid E. linked genes C.chromatin D. A and B are correct DNA replicates in fashion known as meaning that two identical DNA double helices are 82 produced, and each DNA molecule consists of one parental original strand and one newly daughter synthesized complementary strand 82. A semiconservative B. duplcative C synthesis D. dentical E. B and D are corret In monohybrid crosses, the expected ratio of dominant and recessive phenotypes is83 In genetics, 84 is a mechanism that allows males and females to produce the same amounts of proteins that are encoded by genes on the X-chromosome. 84. A. dosage compensation B. hemizygotic C. allelic similarity D. B and C are correct E. none of the answers is correct The position in the DNA molecule where DNA replication initially begins is called 85which is a small section that is unwind in the DNA double helix during DNA replication. 85. A. replication position B. replication fork C. origin of replication D. A and B are correct E. none of the answers is correct

Answer 1

Ans80. B. Recombination

Recombination is a process by which new allelic combinations are formed.

Ans81. E. Linked gene

Linked gene lie in close proximity to each other and do not assort independently.

Ans82. A. Semiconservative.

DNA replicates in a semiconservative fashion.

Ans83. C 3:1

Phenotypic ratio in monohybrid cross is 3 dominant: 1 recessive.

Ans84. A. Dosage compensation

Dosage compensation equalizes the expression of gene in both sexes.

Ans85. C. Origin of replication

Replication usually begins in a small area of DNA called origin of replication
