Given what you know about hymenopterans (bees and ants) how genetically related are two half sisters produced by the same mother (queen) but fathered by two different males (drones) who are themselves brothers? ( 75% ) 50% 25% unknown

In the species Chinchilla chinchilla, Neotropical crepuscular rodent of the parvorder Caviomorpha, a mating between a homozygous long-tailed chinchilla male and a homozygous short chinchilla female will produce all medium length tail chinchilla offspring. When these medium length tail chinchilla offspring F₁ are mated, their offspring consists of 3 tail-less chinchillas, 24 long-tailed chinchillas, 120 medium-length tailed chinchillas, and 15 short-tailed chinchillas. What genetic interaction may be occurring in this population? Please explain

Explain this to me…..

Are mules sterile because they are hybrids of two different species or because they have an odd number of chromosomes?

In the world of Weeping angels, those with pointy wings are (A_), while those with round wings are (aa). In the efforts to explore this extraordinary species, you wish to determine the genotype of a pointy winged angel. Luckily, you have trapped a round winged angel that you can cross your pointy winged angel with. If the pointy winged angel is homozygous what phenotypic ratio do you expect from their offspring? (Pointy wing: round wing) Group of answer choices a. 1:0 b. 2:1 c. 1:1 d. 3:1

Let's go back to the image from the "Think About It." Use your new vocabulary, evidence from the lessons, and scientific reasoning to support the claim, "While there are many types of asexual reproduction, all types result in offspring identical to each other and the original parent." You may include a model or sketch as support for the claim. Submit your optional hand-drawn or digital model or sketch in the file upload question. B I iii !!! (a) (b) (C) (d) (e)

* b. Briefly explain how the use of this molecule (CA1P) disrupts both stages of photosynthesis while the Rubisco enzyme is associated with only one stage. Codule 3: The principles of heredity 1. Let's take the example of the gray kangaroo (Macropus fuliginosus) whose ploidy is 8 and the sexual determinism of this species is carried out according to the XY mode. From a male kangaroo: a) Draw the karyotype of this individual, obtained by stopping division at metaphase. Your drawing should include: a. All maternal and paternal chromosomes involved (different colors) b. An example of autosome and heterochromosome c. An example of homologous chromosome, sister chromatid and centromere. d. The total number of chromosomes in a metaphase kangaroo cell. e. A sentence to explain the difference between the terms gene and allele that might apply to this species.

Q2

In fruit flies, the wild type (red) eye colour is dominant to white eye colour. This gene is carried on the X chromosome. The allele for wild type body colour is dominant to ebony body colour. This gene is carried on the autosome. A wild type female fruit fly that is homozygous for both traits mates with a male fruit fly with white eyes and ebony body colour. What phenotypic ratio would be expected in their offspring? Ratio: A female with red A female with white A male with red A male with white Phenotype: eyes and wild type eyes and ebony eyes and wild type eyes and ebony body colour body colour body colour body colour
