Answer:
50%
Explanation:
According to the given information, the genotype of the mother who is homozygous recessive for gene "A" and homozygous dominant for gene "B"= "aaBB". Likewise, the genotype of the father who is heterozygous for gene "A" and homozygous recessive for gene "B"= "Aabb".
A cross between aaBB and Aabb would produce a progeny in following genotype ratio= 1/2 AaBb : 1/2 aaBb
Therefore, there are 50% chances for this couple to have a child heterozygous for both A and B genes (AaBb).
Answer:
cornea
Explanation:
When light rays reflect off an object and enter the eyes through the cornea (the transparent outer covering of the eye), you can then see that object. The cornea bends, or refracts, the rays that pass through the round hole of the pupil.
Arterial blood pressure reflects two factors:
How much the elastic arteries close to the heart can be stretched (their compliance or dispensability)
The volume of blood forced into them at any time. If the amounts of blood entering and leaving the elastic arteries in a given period were equal, arterial pressure would be constant. Blood pressure rises and falls in a regular fashion in the elastic arteries near the heart.
What feature distinguishes an arteriole from a venule in a systemic capillary network? An arteriole carries oxygenated blood to capillaries, while a venule carries deoxygenated blood away from capillaries.
The answer is seminiferous tubules to epididymis to ductus deferens to urethra. In the Test is where the spermatozoa are produced, epididymis is the room place for the sperm cells. The ejaculation path of the sperm is formed by the two vas deferens, both ejaculatory ducts, and the urethra.
