2. In crossing a homozygous recessive with a heterozygote, what is the chance of ... In cattle, roan color (mixed red and white hairs) occurs in the heterozygous (Rr) ... with another roan (Rr x Rr), will result in 1:2:1 genotypic and phenotypic ratio. ... In humans, the allele for short fingers is dominant over that for long fingers.Answer:
Explanation:
Two genetically identical daughter nuclei.
Answer:
Explanation:
A. There is a greater risk of E.coli infection from hamburger consumption than in steak. Hamburger is made with ground beef and bacteria which includes E.coli spreads more in ground beef. On the contrary, steak is not ground meat so the spread of bacteria in it is reduced compared to hamburger.
B. Food poisoning can still occur. Though staphylococcus aureus can easily be killed by the heat associated with warming, it's toxins which are responsible for food poisoning are heat resistant and can still cause diseases even after reheating of food.
Answer:
b. Synergistic dominance
Explanation:
The stabilizing muscles will always be <u>synergistic</u>, since only from the synergies (hence the term synergist) that arise from joint work is efficient and controlled movement possible. However, not all synergists will be stabilizers. Stabilizer will be one that, thanks to the geometric arrangement of its fibers, will have the ability to maintain alignment in the joint and stable the axis of rotation.
In the case of knee extension, we would have as stabilizers all the antagonists who, because the flexion axis is virtual and not physical, must maintain the stability of said axis. If the axle were physical, such as the wheel in a horse carriage, or on a skateboard through the bearings, the antagonistic muscles would not be necessary for this purpose, because the fixed axis would maintain the position. Since the joints of living beings do not have a fixed physical axis, it is the muscles themselves, specifically the antagonists, who must be responsible for maintaining the stability of the joint creating a virtual axis on which rotation occurs.
