Question

The type of sex determination in honey bee is:

• A. Haplo-diploidy
• B. Haploidy
• C. Diploidy
• D. ZZ-ZW

Answer 1

The Correct Option is A

Haplodiploidy is seen in honeybees. It is a sex-determination system in which males develop from unfertilized eggs and are haploid, and females develop from fertilized eggs and are diploid.

Answer 2

The fertilization and non-fertilization of eggs is the primary method used to determine sex in honey bees. This method of sex identification was developed in 1845 by Johann Dzierzon.

The male progeny in the haplodiploid system develops from unfertilized eggs.

 

The eggs only contain one set of chromosomes since they are haploid. Drones or male honeybees are what they are. The fertilized honey bee eggs, which have two sets of chromosomes and function as diploid eggs, give rise to the queens and worker bees.

In honeybees, this sort of haplodiploid sex determination can be seen.

In birds, sex is determined via the ZZ and ZW types of sex determination, where females are heterozygous (ZW) and males are homozygous (ZZ).

Thus, the choice is the right response (A).

 

Answer 3

As opposed to the presence or lack of sex chromosomes, the fertilization or non-fertilization of eggs often determines the sex of honeybees.

The male honey bee is haploid, whereas the female is diploid.

Due to the parthenogenetic development of male insects from unfertilized eggs, they are haploid.

Arrhenotoky is the name of the phenomenon.

Females are diploid because they develop from fertilized eggs.

Certain insects, like bees, ants, and wasps, are haplodiploid.

In addition, the haploid drones contain 16 chromosomes whereas the diploid queen has 32. Drones generate sperm cells that are genetically similar to one another aside from minor changes since they carry their full genome.

So, the genetic make-up of male bees derives fully from the mother, whereas the genetic make-up of female worker bees derives only partially from the mother and a half from the father.

2. In honey bees, all of the sperm are similar when the father is haploid (except for a small number where gene mutations have taken place in the germline). Therefore, the chromosomes of the father are passed down to all female kids.

3. If a female has only mated with one guy, all of her daughters will inherit all of that male's chromosomes.

4. In Hymenoptera, the males often generate enough sperm so that, after only one mating with that male, the female can utilize those sperm from her spermatheca for the rest of her life.

5. The complementary sex determiner (CSD) gene was discovered as a result of the isolation of the sex determination locus in honey bees.

6. Female development requires the CSD gene product because the silencing of the

CSD gene product in female embryos causes a full switch to male development.

Recently, the target of the CSD gene product was identified as the feminizer (fem) gene.

So, the answer is B. Haplodiploidy
