Answer: Option B
Diploid means that organism has a pair of all the chromosomes. Since M. pilosula has only one chromosome, diploid female will have a set of it, which means it will have a pair of homologous chromosomes. That means each chromosome will have an allele for F and an allele for G.
Add Answer to:
The ant M. pilosula stores its entire genome on one chromosome. Females are diploid (2n). Two genes F and G are identif...

The figure below shows one unreplicated chromosome with its centromere (left side) and then the same chromosome after DNA replication "S") (right side). The letters by each dash represent alleles for two different kinds of genes: there is the "r" allele for one type of gene and the "H" allele for a second kind of gene. In genetics, letters represent different kinds of genes and uppercase vs lowercase letters represent different alleles for the same gene: e.g., purple allele (P)...

2. A diploid cell contains two pairs of chromosomes, which we will call 1 and 2. Assume chromosome! is clearly larger than chromosome 2. Each chromosome pair contains a maternal and a paternal member (e.g. 1 and 1 & 2 and 2"). An allele called G is localized to 1" whereas an allele called g is on chromosome 1P. Allele R is localized to 2m whereas alleler is localized to 2. Using these designations and clearly drawn and labeled chromosomes,...

Merfolk have three pairs of autosomes and one sex chromosome; males are X0 and females are XX. In merfolk the genes controlling tail fin shape and scale colour are on different autosomes. Solid tail fin (Ff) is dominant to forked tail fin (ff), and the F allele is recessive lethal. There are two alleles of the scale colour gene – CB(blue) and CR (red)– CB and CR show incomplete dominance with heterozygotes being purple. The silent trait is X-linked and...

A cell's genome is its blueprint for life. However, what is the bare minimum number of genes needed to sustain a free-living cell? This is a question that microbiologists at the J. Craig Venter Institute (JCVI) have attempted to answer ever since they sequenced the genomes of several Mycoplasma species in the 1990s. Because Mycoplasma species are parasitic bacteria, their genomes are already reduced in size and hence provide an excellent foundation for creating a "minimal cell." However, little did...
