Bottlenecks and founder effects. Genetic drift can cause big losses of genetic variation for small populations. Population bottlenecks occur when a populations size is reduced for at least one generation... reduced genetic variation from the original population

In maize, a dominant allele A is necessary for seed color, as opposed to colorless (a). Another gene has a recessive allele wx t

Gelneren [198K]

Answer:

1/2 Aa Wx wx (colored seeds, normal starch)
1/2 aa Wx wx (colorless seed, normal starch).

Explanation:

A (colored seed) is dominant over a (colorless)
Wx (normal starch) is dominant over wx (waxy)

Both loci are independent.

A Aa WxWx individual was test crossed (crossed with a homozygous recessive aa wxwx individual).

The homozygous recessive can only produce a wx gametes.
The dihybrid individual can produce two types of gametes, all of them with the same frequency because the genes segregate independently: 1/2 A Wx and 1/2 a Wx

The possible offspring resulting from the combination of those gametes is:

1/2 Aa Wx wx (colored seeds, normal starch)
1/2 aa Wx wx (colorless seed, normal starch).

If a physicist performs an experiment, who would likely try to replicate it?

Alenkasestr [34]

Answer:

The physicist himself

Explanation:

Replication in an experiment means to repeat an experiment as many times as possible using the same conditions. This is done to minimize error and ascertain the reliability of the experimental outcome.

An experimenter is responsible for repeating his/her experiments. According to this question, a physicist performs an experiment. The physicist himself should replicate his experiment.
