A scientist crosses a rabbit with short fur and a rabbit with long fur. which of these outcomes would show that the trait for fu
maks197457 [2]

Answer:

d. all of the offspring have medium length fur.

Explanation:

Incomplete dominance is a phenomenon in which offspring produce a trait that is intermediate between the two forms of a certain trait.

For example: In four o clock plant, some plants produce red flowers while some plants produce white flowers. When plants with red flowers are crossed with plants with white flowers, all the offspring have pink flowers.

Why is that so?

This is because no allele is completely dominant over the other and therefore both contribute their individual effect by producing intermediate phenotype.

Example in question:

Cross between a rabbit with short fur (SS) and a rabbit with long fur (LL)

P1:                                SS        x        LL

Gametes:                     S     and  L

Offspring                        SL :SL

SL: Medium length fur

Therefore this is a case of incomplete dominance.

Hope it help!

What form of natural selection is acting on beak length in soapberry bug populations feeding on the different fruits?soapberry b
Lilit [14]
Bugs with shorter bills had more access to sustenance, enabling them to deliver all the more posterity. Bugs that happened to have short breaks were better ready to feast upon the little organic products. Their expanded access to nourishment enabled them to deliver all the more posterity, which likewise had little snouts. In any case, bugs with little bills did not emerge so as to feast upon the little natural products. Transformative change comes to fruition as the extent of people in the populace showing a specific characteristic increments from age to age. The characteristic does not change step by step in all individuals from the populace.
