Answer:
Parent´s chances:
- Mom´s chances of giving their children the big feet allele are 2 out of 2, or 100%
- Mom´s chances of giving their children the small feet allele are 0 out of 2, or 0%
- Dad´s chances of giving their children the big feet allele are 1 out of 2, or 50%.
- Dad´s chances of giving their children the small feet allele are 1 out of 2, or 50%
Offspring chances:
- The offspring have 4 out of 4 or 100% of probability of having big feet. And 0 over 4 or 0% of probabilities of having short feet.

Answer:
i only have #1 but it is mainly because of chemicals and an increase of moths themselves
Explanation:
It might be stated that his reliability might be compromised because he writes the story many years later and his memories may be skewed. he is the narrator and the protagonist of the story and it is written in first person so he retells what he remembers from his life experience since he was a child.
Answer:
Few crosses
The complexity of cat genetics
Crosses not controlled by the researcher
Explanation:
The purpose of this question is to determine why Megor Grendel is less famous than that of Gregor Mendel.
Gregor Mendel examined pea plants, which have a number of benefits for deducing genetic rules, including:
- The researcher has total control over the crosses.
- Because the peas have both self and cross-fertilization, it is possible to alter the crosses in the simplest way possible.
- Pea plants may be examined for a greater series of generations than cats or other animals.
- Because plant genetics is not overly complicated, several traits may be investigated at the same period.
As a result, the primary factors why Megor Grendel's experiments are not well-known:
- The presence of only a few crossings: It is impossible to establish a genetic theory with such a small number of crossings on the test subject of the organism.
- Cat genetics is too complicated therefore, the fur gene color on the X-chromosome, a characteristics mosaic inheritance. As a result, It is much too complicated to deduce an inheritance pattern.
- Crossings that the researcher cannot fully control. Unlike plants, crosses in animals cannot be totally controlled by the researcher.
As a result, it is impossible to draw any conclusions from them.
Answer:
a.There are three signaling pathway
1- Reception in which molecule binds to receptor
2- Signal transduction in which activation of intracellular pathway and enzyme occur.
3- Cellular response in which specific response of cell occur according to receptor and ligand.
b. Three types of receptors are
1- autocrine
2- paracrine
3- endocrine.
Explanation:
autocrine receptors are signaling pathway in which cell releases its molecule and bind to its own cell receptor example cancer cells while paracrine in which ligand binds to other nearby cell receptor and it is used during development and in endocrine cell target distinct cell and travel through blood stream like hormones functioning.
