You have crossed two Mexican hairless dogs, and the offspring are 1/3 hairy and 2/3 hairless. Given this phenotypic ratio, draw the Punnett square for this cross. Indicate the phenotype for each of the possible offspring. What are the genotypes of the P1 and F1 dogs in this crosList the predicted genotype as well as the phenotype for each of the offspring. Which genotypes are hairless and which are hairy? List the predicted genotype as well as the phenotype for each of the offspring. Which genotypes are hairless and which are hairy? Can you design a genetic cross that would yield a true breeding hairless line-where all offspring is hairless?
Answer:
- Punnett square:
H - h
H - HH (lethal) Hh (hairless)
h - Hh (hairless) hh (hairy)
- Cross: Hh × Hh (all genotypes are Hh)
- Genotypes of the P1 dogs: heterozygous (Hh)
- Genotypes of the F1 dogs: 1/3 hh; 2/3 Hh
- It is not possible to design a cross where all offspring are hairless because the H allele for hairless is lethal in homo-zygous condition (the maximum possible is 2/3 hairless individuals)
Explanation:
As you can see in the Punnett square above, the 1:2 ratio (i.e., 1/3 hairy and 2/3 hairless) is indicative that the hair phenotype is a single (monogenic) trait associated with a lethal allele (H allele). In this case, it should be impossible to design a true-breeding cross because the homo-zygous HH genotype is lethal. Alleles that cause the death of an organism are known as lethal alleles (in this case, the H allele). A recessive lethal allele is only lethal in the homo-zygous individuals, thereby heterozygous individuals survive and they may exhibit a normal/altered (non-lethal) phenotype.
10. Most cells are microscopic. Very few, like the eggs we eat, are visible to the unaided eye. Why have cells evolved to be small versus very large structures visible to the human eye
Answer: Efficient functioning.
Explanation:
Cells require a lot of substances to both come into and leave the cell in order for the cell to accomplish it's functions. These substances can be anything from carbohydrates to water and they come into the cell through diffusion and osmosis.
The thing about diffusion however, is that it happens faster over shorter distances than longer distances. This is why cells are so small. They evolved to be that size to ensure that diffusion of these substances takes place relatively quickly so that they can use these substances to carry out their functions at a faster rate.

True or false. The cell's chromatin condenses into chromosomes during prophase.
Answer:
False
Explanation:
Microtubules move chromatids to the poles of the cell during anaphase. Chromosomes reach the poles of the cell during metaphase. The cell's chromatin condenses into chromosomes during prophase. ... false, centrioles migrate to the poles of the cell during prophase.
If organisms inherited traits via blending inheritance, rather than Mendelian inheritance, what would we expect the offspring (F1 generation) of a blue-flowered plant and a yellow-flowered plant to look like
Answer:
green-flowered plants
Explanation:
In biology, blending inheritance refers to an erroneous theory from the XIX century, which proposed that the progeny (F1) inherits phenotypic traits as an average of parental phenotypic values. If this theory would be true then a crossing of a blue flower variety with a yellow variety of the same species would produce green-flowered progeny (since green is a combination of blue and yellow). Charles Darwin used pangenesis, a hypothetical mechanism for heredity that implied blending inheritance, in order to understand the transmission of hereditary characters. Darwin believed that different parts of the body generated heredity particles called 'gemmules' that aggregated in the gonads, and contributed to the transmission of heritable information to the next generation. The blending inheritance theory was replaced by Mendelian inheritance during the early 1900s.

Part C - Follicles Kate thought it was interesting that, after the release of a mature oocyte from the ovary, the follicle it was released from took on a new role. What happens to the follicle
Answer: The follicle assumes a new role which is:
--> the secretion of hormone PROGESTERONE and
--> OESTROGEN
Explanation:
The cycle in the female reproductive system of humans which tak s 28dayd to complete is known as menstrual cycle. At the beginning of the menstrual cycle, several primary oocytes begin to develop. Each oocyte is surrounded by actively dividing granular cells from which it receives nutrients. The whole structure is called a FOLLICLE.
A developing follicle secretes OESTROGEN.
Usually, only one of the developing follicles becomes mature to produce an ovum. As the follicle matures, it becomes filled with fluid and the oocyte is pushed to one side. Ovulation occur when there is release of an ovum from a mature follicle.
The ruptured mature follicle develops into a CORPUS LUTEUM which is a solid yellow body that secretes the hormone PROGESTERONE. This is the hormone that helps to maintain the early stages of pregnancy if fertilization and implantation of embryo occurs. In the absence of pregnancy, the corpus luteum shrivels.
In a female, several main oocytes begin to mature at the start of the menstrual cycle. Each of the oocyte is surrounded by granular cells that are actively dividing and provide it with nourishment forming a ball like mass structure. This structure is known as a follicle.
After the release of a mature oocyte from the ovary, the follicle it was released from takes on a new role and becomes the Corpus luteum.
The ruptured mature follicle after releasing the one main oocyte that develops into the egg develops into a Corpus Luteum. This structure functions in the secretion of the hormone known as progesterone.
If fertilization and embryo implantation occur, this hormone helps to maintain the early stages of pregnancy. The corpus luteum shrinks in the absence of pregnancy.

Which of the following is the best example of homeostasis in the human body?
Answer:
Humans' internal body temperature is a great example of homeostasis. When someone is healthy, their body maintains a temperature close to 98.6 degrees Fahrenheit (37 degrees Celsius). Being warm-blooded creatures, humans can increase or decrease temperature internally to keep it at a desirable level

Explanation:
In Drosophila, the genes r and s are linked. Flies of genotype r s/r s and rs /rs are crossed and an F1 obtained. The F1 allele arrangement is called:
Answer:
repulsion (trans)
Explanation:
Repulsion refers to the phenomenon by which each homologous chromosome contains one dominant and one recessive allele from two different linked genes. A trans arrangement occurs when an individual is heterozygous for two linked genes, where the recessive allele for one particular gene is located on the same chromosome as the dominant allele for the other linked gene, thereby dominant and recessive alleles are said to be “in repulsion”. Conversely, a cis arrangement occurs when both dominant alleles are located on one chromosome and both recessive alleles on the other.
