Svetradugi [14.3K]

Answer:

2.Less than 73% of the populations would have only one allele present.

Explanation:

The two alleles chosen do not affect the fitness of flies in the lab environment, so Kerr and Wright could be confident that if changes in the frequency of normal and forked phenotypes occurred, they would not be due to natural selection.

Using a larger breeding population would not be expected to alter the outcome of the experiment.

Which of the following is the adaptation that allows animals to survive in high altitudes which contains lower levels of oxygen
Law Incorporation [45]

The correct answer is option B. Higher levels of haemoglobin

A higher level of the haemoglobin allows the organism to survive in low oxygen condition. The low oxygen level decreases the amount of oxygen delivered to the cells, to cope up this condition, there is an increase in the haemoglobin content. The increased haemoglobin concentration allows the delivery of  the sufficient amount of oxygen, as the number of haemoglobin increase, the capacity of oxygen carried to the cell is increased.

Pea flowers may be purple (P) or white (p). Pea seeds may be round (R) or wrinkled (r). What proportion of the offspring from th
Mumz [18]
When crossing alleles for color, you get
25% pp
50% Pp
25% PP
White flowers are recessive, so there is a 1/4 chance

And when crossing alleles for shape you get
25% rr
50% Rr
25% RR
Wrinkled seeds are recessive so there is a 1/4 chance


Since you are looking for white flowers AND wrinkled seeds, you need to multiply 1/4 x 1/4, giving you a 1/16 chance that the offspring will have these two traits

-Dominant- [34]

Answer:

Ralph is looking at a vein (likely a muscular vein).

Explanation:

Of all three great types of vessel present in vertebrates (arterial, venous, lymphatic), only veins and lymphatic vessels may normally contain valves.  This is an essential feature of vessels which present low pressure flow, since it ensures that such flow is unidirectional.

Since blood cells are not typically found in lymphatic vessels, the vessel in question can be assumed to be a vein.
