The  mode of Protenor butterfly sex determination is based on ________.   ZW and ZZ for females and males, respectively. XX and XO for hermaphrodites and males, respectively. XX and XY chromosomes for females and males, respectively. XX and XO chromosomes for females and males, respectively. XO and YY chromosomes for females and males, respectively.

Non-disjunction occurs during meiosis II. This will result in _____ abnormal gametes being produced.   Question options:   2   3   1   4

Match each hypothesis to its theory. Preformationism Genetic information is inherited from one parent or the other, not both. Pangenesis concept Reproductive cells have complete genetic codes for their species. Germ-plasm theory Cells in different tissues have unique genetic codes that are transferred to the gonads to produce gametes.

In meiosis _______ are separated during anaphase I, and _______ are separated during anaphase II

In humans and fruit flies, males have a Y chromosome and only one X chromosome. Compared to females, males are __ for X-linked genes. O haploid homozygous heterozygous diploid

Usually, if a gene that affects a particular genetic trait is NOT located on a sex chromosome, then consequently (click all that apply) it is an autosomal gene. a diploid cell should have at least two copies of this gene during G1 phase. this gene will be absent from the genomes of gametes. this trait should appear with roughly equal frequency in males and females. this trait must be “dominant.”

it is possible that an alternative mechanism for generating germ cells could have evolved. consider meiosis in a germ cell precursor. if the S shape were skipped, whic meiotic devision would no longer be required.

Based on this karyotype, what proportion of this women's gametes (i.e., eggs) would produce viable embryo's? By viable I mean normal phenotype where the baby can survive without any genetic disease.

In fertilization,  select answer   a male gamete and a female gamete two female gametes two male gametes  fuse to produce a      select answer   zygote female germ cell male germ cell

A Tasmanian Devil has a diploid number of 14. How many chromosomes would be in a Tasmanian Devil zygote? _________ In a Tasmanian Devil gamete? _______ In a Tasmanian Devil liver cell? ________
