In guinea pigs the allele for black fur (B) is dominant over the allele for brown fur (b), and the allele for short fur (F) is dominant over the allele for long fur (f). What percentage of the offspring from a BBFF x bbff cross would be expected to be heterozygous for both traits?

Answers

Answer:

100%

Explanation:

This question involves two genes in guinea pigs; one coding for fur color and the other for fur length. The alleles of black fur (B) and short fur (F) is dominant over the alleles for brown fur (b) and long fur (f).

In a cross between two offsprings with genotypes: BBFF x bbff, the following gametes will be produced by each parent:

BBFF - BF, BF, BF, and BF

bbff - bf, bf, bf, bf

Using these gametes in a punnet square (see attached image), one will notice that all of the offsprings will have the genotype: BbFf i.e all or 100% of the offsprings are heterozygous for both of the genes or traits.

question



A student poured a solution of bromothymol blue indicator into three test tubes. Then he placed an aquatic plant in two of the test tubes, as shown below. He placed a stopper on each test tube and placed them all in the dark for 24 hours. Bromothymol blue turns from blue to yellow in the presence of CO2


Predict what will happen to the test tubes in Figure 9–9 after 24 hours in the dark.

Answers

In the dark the aquatic plant won't do photosynthesis. Instead it will do cellular respiration in which it will produce CO2. Therefore after 24 hours of letting the plant in the dark introducing Bromothymol in the solution will cause it to turn yellow.

What is terrestrial species?

An animal or plant that lives on land or in the ground, as opposed to the sea, trees, or the air, is said to be terrestrial. There are occasionally aquatic and terrestrial animals seen sleeping next to each other under a loose stone.

These animals can run quickly because the majority of them have legs. They must move quickly to capture their prey or avoid being an animal's next meal (predators). Komodo dragons and red-tailed boas have so many differences, even though they share a common ancestor.

Therefore, Order Urodela has amphibian with aquatic and terrestrial species with very flexible bodies, has a tail, and retains its juvenile features throughout its life.
