Chapter 13, Problem 1SA

A heterozygous individual has _______ for a trait being studied.

a. the same allele on both homologous chromosomes

b. two different alleles of a gene

c. a haploid condition, in genetic terms

Expert Solution & Answer

Summary Introduction

Introduction:

Individuals in the population carry a specific set of alleles, known as genotype. The examples of genotype are homozygous and heterozygous. The phenotype of a plant depends on its genotype, and it is the trait of the individual that can be observed.

Answer to Problem 1SA

Correct answer:

Two different alleles of a gene are carried by a heterozygous individual for a trait being studied. Hence, the correct answer is option b.

Explanation of Solution

Reason for correct answer:

Option b. is given as “two different alleles of a gene.”

Locus represents the “location of a gene” on a chromosome. Individuals carry two copies of a gene because their cells are diploid and pairs of the chromosome are present in these cells. These double copies of any gene can be similar, or they can vary as alleles. If an individual carries two different alleles at a particular locus then its genotype would be called heterozygous.

Reason for incorrect answer:

Option a. is given as, “the same allele on both homologous chromosomes.”

If an individual has the same allele on both homologous chromosomes then the individual would be known as homozygous. Hence, option a. is incorrect.

Option c. is given as, “a haploid condition, in genetic terms.”

In individuals there are always two copies of genes are present. So, a heterozygous individual is a diploid condition, not a haploid condition. Hence, option c. is incorrect.

Hence, the options a. and c. are incorrect.

Conclusion

Therefore, the alleles of a gene on both homologous chromosomes would be different in a heterozygous individual. Thus, the correct option is b.

Three of the many recessive mutations in Drosophila melanogaster that affect body color, wing shape, or bristle morphology are black (b) body versus grey in wild type, dumpy (dp), obliquely truncated wings versus long wings in the male, and hooked (hk) bristles versus not hooked in the wild type. From a cross of a dumpy female with a black and hooked male, all of the F1 were wild type for all three of the characters. The testcross of an F1 female with a dumpy, black, hooked male gave the following results: Trait Number of individuals Wild type 169 Black 19 Black, hooked 301 Dumpy, hooked 21 Hooked, dumpy, black 172 Dumpy, black 6 Dumpy 305 Hooked 8 Determine the order of the genes and the mapping distance between genes. Determine the coefficient of confidence for the portion of the chromosome involved in the cross. How much interference takes place in the cross?

What happens to a microbes membrane at colder temperature?

Genes at loci f, m, and w are linked, but their order is unknown. The F1 heterozygotes from a cross of FFMMWW x ffmmww are test crossed. The most frequent phenotypes in the test cross progeny will be FMW and fmw regardless of what the gene order turns out to be. What classes of testcross progeny (phenotypes) would be least frequent if locus m is in the middle? What classes would be least frequent if locus f is in the middle? What classes would be least frequent if locus w is in the middle?
