Answer #1

Sex determination in grasshopper is determined on the basis of XO system. The males are heterogametic with the genotype of XO and the females are homogametic with the genotype of XX.

XO, 23 (male) × XX, 24 (female)

Gametes X, 12 X, 12
X, 12 XX, 24, female XX, 24, female
O, 11 XO, 23, male XO, 23, male

The description are sex chromosomes and chromosome number in male and female offspring is written in the table itself.

Please rate high.

    AP Question 4 In the tongue sole fish (Cynoglossus semilaevis), sex is determined by a combination of genetics and environmental temperature. Genetically male fish have two Z chromosomes (ZZ), and genetically female fish have one Z chromosome and one W chromosome (ZW). When fish are raised at 22°C, ZZ fish develop into phenotypic males and ZW fish develop into phenotypic females. However, when fish are raised at 28°C, the Z chromosome is modified (denoted as Z*). Z*W individuals develop as...

    The sex of an organism is typically determined genetically, but environmental factors can also play a role. Scientists examined the roles of genes and environmental temperature in the sex determination of a lizard species. Individuals with a ZW pair of chromosomes are always female (ZWf), while individuals with a ZZ pair of chromosomes can be either male (ZZm) or female (ZZf). Scientists mated ZWfor ZZf females with ZZm males and incubated the eggs produced in 20 clutches at temperatures ranging...

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...
