Answer #1

In insects, sex is determined on the basis of ZZ/ZW system. The female is heterogametic (ZW) and male is homogametic (ZZ).

In a karyotype, the last two chromosomes are sex chromosomes. If they are same than it is homogametic and they are different than it is heterogametic.

The one on the right side is female (ZW, heterogametic) and the one on the left side is male (ZZ, homogametic).

    Birds, unlike mammals, have a sex determination system in which females have Z and a W chromosome (ZW), while males have two copies of Z (ZZ). Another fun fact: most bird species, including chickens, do not have penises. This makes it hard to determine the sex of baby chicks! There’s a gene required for pigmentation located on Z. The “barred” allele (b) of this gene is recessive to the black allele (B). If you would like to easily determine the...

    Solve It: Does Sex Determination Have Only Two Possible Outcomes: Male or Female? One of the most fundamental aspects of personhood is your biological sex: "It's a girl" or "It's a boyl" is often the first statement about who you are. Most people view biological sex as a straightforward, eitherfor issue-either a person is biologically male or biologically female. Like all biological characteristics, however, sex determination is achieved through a developmental process. All developmental processes exhibit variation, and sex determination...

    (2points) You are studying a species of alga. Haploid cells have 17 chromosomes. Is this surprising that this is an odd number? Why or why not? (2points) You are studying a species of single-celled yeast. For a group of cells that you are studying, you notice that during mitosis, some cells have 5 groups of chromosomes on the metaphase plate and others have 10 groups of chromosomes. What do you think is going on? 2. You are studying a species...

    You are working with two forms of progressive retinal atrophy (PRA) in dogs--one form in Siberian Huskies, which is a sex-linked recessive allele, and one form in Labs, which is an autosomal recessive. Each breed is normal for the disease allele in the other breed. Assume you mate a Siberian male with the disorder to a female Lab with the disorder. (Assume homozygosity for the normal allele.) A) What is the phenotypic distribution of the progeny from this mating (include...

    Drosophila Genetics predictions exercise-L113 (25 pts.) Part I. Meiosis and Punnett Squares Remember, whenever you use Punnett Squares to solve genetics problems, be sure you are completing each of the following steps: 1) Identify the genotypes of the parents. 2) For the specific traits of interest, figure out what kinds of haploid gametes each parent can make. In each gamete, there should be one allele for each trait of interest. If there is more than one trait, make sure all...
