A black guinea pig crossed with an albino guinea pig produced 12 black offspring. When the albino was crossed with a second black one, 7 blacks and 5 albinos were obtained. What is the best explanation for this genetic situation? Write genotypes for the parents, gametes, and offspring.Black appears dominant to albino
B - black (both BB and Bb genotypes)
b - albino (bb genotype)
This is a problem showing that 1 phenotype (black color) can be the result of two different genotypes (BB and Bb). These two crosses would be the equivalent of test crosses to determine genotype.
A black guinea pig crossed with an albino guinea pig produced 12 black offspring. This is the result (all black offspring) you would expect when breeding two true breeders (Two homozygotes BB x bb).

When the albino was crossed with a second black one, 7 blacks and 5 albinos were obtained. This looks like the results you would expect between a heterozygote and an albino (Bb x bb).

Answer:

A black guinea pig crossed with an albino guinea pig producing 12 black offspring

b b

B Bb Bb

The genotype of the black gunea pig will be BB in this situation and the genotype for the albino pig would be bb.

The gametes formed will be B, B,b, b.

The offsprings will have genotype Bb. They will be heterozygous black.

When the albino was crossed with a second black one, 7 blacks and 5 albinos were obtained

b b

B Bb Bb

b bb bb

The genotype of the black parent will be heterozygous i.e Bb in this condition. The genotype of the albino parent will be bb.

The gametes formed will be B,b,b,b.

50% of the offsprings will have the probability of having heterozygous Bb genotype. 50% of the offsprings will have the probability of having albino bb genotype.

The hydrophobic tails of a phospholipid bilayer are oriented toward the:

Answers

The tails point inwards. Since the outside layer of the bilayer is in a watery environment, it needs to be hydrophilic. Therefore, the hydrophobic tails point inwards while the hydrophilic heads point outwards.

If a plant has a mutation and cannot produce Casparian strips, what process won't it be able to do?

Answers

If a plant has no Casparian strips, it will not be able to control the amount of water it absorbs and solutes. Casparian strips regulate the amount of water that gets to the xylem. Without it, a plant won’t be able to control the amount of water going to the xylem.

If a plant has a mutation and cannot produce casparian strips, the process that it will not be able to do is to control the amounts of water and solutes it absorbs. These casparian strips are found in the roots of plants.

Which of the points of natural selection is also referred to as "survival of the fittest"? More offspring are born than can be supported by the environment.
