Traits And A Golden Retriever

Homozygous: Refers to expressing the same alleles for a particular trait. If black was dominant for the above chicken, and the alleles were coded for by B, if it was homozygous, the chicken’s genotype would be BB.

p2 + 2pq + q2 = 1 ; where ‘p2’ represents the homozygous dominant genotype, ‘2pq’ represents the heterozygous genotype, and ‘q2’ represents the homozygous recessive genotype

Traits get passed down from one generation to the next through Meiosis (cell division), where each parent gives you one Gene for each trait.

If your offspring genotypes include 1 GG, 2 Gg, and 1 gg, the ratio would be: 1 GG : 2 Gg : 1 gg

---If given traits and parents, be able to use a Punnett square or patterns to predict the probability of offspring for a given cross and express it as a fraction, percent, or ratio.---

* How is it possible for an offspring to exhibit a recessive trait if neither parent exhibited that

Imagine that you are crossing two plants that are heterozygous for flower color and seed shape. The dominant and recessive alleles for these traits are:

While studying eugenics, genetics plays a detrimental role in determining heredity. Genetics is the study and behavior of genes ("Genetics"). These genes are encoded pieces of information that comes from both parents, these genes are found on any of the 23 pairs chromosomes; these chromosomes that contain genes form the human genome. 22 chromosomes all contain the same genes although slight variations of alleles, alleles are alternate forms of genes, and the 23rd chromosome contains the information for the zygote's gender.

Now you have determined some facts about the grounded allele and the trait that it causes. Given what you know, do you expect the mutant F1 flies to be homozygous or heterozygous for the allele that causes the grounded trait? According to your reasoning, if you mated two mutant F1 flies, what percentage of flies would you expect to be wild type versus mutant in the F2 progeny? Draw a Punnett square of this cross to justify your answer.

You are also provided with a heterozygous female, and a homozygous recessive male for a genetic cross. In this particular female, all the dominant alleles are on one chromosome, and the recessive counterparts are on the other homologous chromosome. Due to a chromosomal condition, in the female no recombination occurs between the M and N loci. Normal recombination occurs between the L and M loci. Diagram this cross, and show the genotypes and frequencies of all offspring expected from this cross.

33. What is the phenotype ratio of the offspring in the Punnett square shown in Figure 11-2?

Based on your results for the female offspring, predict whether color blindness is a dominant or recessive trait. Explain your reasoning.

I agree that I am a golden retriever because the qualities of a golden retriever match my personality the best. I don’t think any other animals best match me. I don’t think any other animal match me because I don’t have the qualities of the other animal such as lions, otters, or beavers. I believe I possess qualities such as witty, caring, and loving so I am a golden retriever. I am not a conflict maker, but I will make conflict if I am forced to, I am not scared of conflict but try to avoid it. But will face it if need being. I am a quiet person unless we are on a topic I care about, then I will voice my opinion and much more. Generally, don’t talk over people when they are speaking unless talking to a friend. Also, Mrs. Fette told me to add

Chromosomes line up in different orders (random assortment) so when they go to either new cell on cell might have dominant for one characteristic (e.g. brown eyes), recessive for another (e.g. blond hair), and dominant for a third one (e.g. can roll tongue) whereas the other created cell might be dominant, dominant dominant (brown eyes, brown hair and can roll tongue.

This table helps show all the possible genotypes from one set of parents. The table shows that the genotypes purple and starchy are dominant, and the genotypes yellow and sweet are recessive.(stallsmith)
