-Dominant- [34]4 years ago
8 0

Answer:

The hypothesis that states that viruses originated from more complex cells is called the regressive hypothesis.

Explanation:

The regressive hypothesis -also called <u>degenerative hypothesis</u>- raises the possibility that viruses originally were cells that behaved as symbionts or parasites of other cells, and this condition of dependence could have originated the disappearance of genes, becoming structures formed by nucleic acid inside a viral capsid (virus).

Some evidence gathered to support this theory suggests that some bacteria, such as rickettsia, need to parasitize a cell in order to replicate, just as viruses do.

A male is heterozygous for the trait that produces freckles on the skin, and he has freckles. if he marries a woman who is also
kakasveta [241]
<span>F- allele for freckles
f- </span><span>allele without freckles

1) The man is heterozygote and has freckles, its indicating that the allele for freckles is dominant.
A cross between him and a woman who is also </span><span>heterozygote: Ff x Ff
it would result in the following probabilities:
- 1/4 - homozygote with freckles: FF
- 2/4 - </span><span>heterozygote with freckles: Ff
- 1/4- </span><span>homozygote without freckles:ff

Their son would have a probability of 75% of being born with freckles.


2) The cross resulted in this probabilities:
</span><span><span>- 1/4 - homozygote with freckles: FF
- 2/4 - </span><span>heterozygote with freckles: Ff
- 1/4- </span><span>homozygote without freckles:ff
So, the chance of being born heterozygote for this gene is 2/4, which is the same as half (50%).
