Given two guinea pigs with genotypes Bb and bb.
We use a Punnett square to show the possible phenotypes.
B b
b Bb bb
b Bb bb
So there are two possible phenotypes, Black fur (heterozygous) and white fur (heterozygous recessive).
She's making a karyotype.
A karyotype is some sort of image to be ablo to make an analysis to a persons chromossome. To make one, scientists take a picture of the chromossome in a cell trough a microscope of course, and then cut it out leaving only the chromossome.
Hope it helped,

Answer:
<em>The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the atmosphere and the surface of the Earth.</em>
<u> Allele frequencies to change from one generation to the next.-</u>
<u>B. </u><u>Mutation</u><u>; C. Random genetic drift; D. </u><u>Migration</u><u>; F. Natural selection</u>
- Selection, mutation, migration, and genetic drift are the mechanisms that effect changes in allele frequencies.
- When one or more of these forces are acting, the population violates Hardy-Weinberg assumptions, and evolution occurs.
Why do allele frequencies change from one generation to the next?
Random selection: Allele frequencies may fluctuate from one generation to the next when people with particular genotypes outlive those with different genotypes.
No mutation: Allele frequencies may fluctuate from one generation to the next if new alleles are produced via mutation or if alleles mutate at different rates.
What are 5 factors that cause changes in allele frequency?
- A population, a collection of interacting individuals of a single species, exhibits a change in allele frequency from one generation to the next due to five main processes.
- These include natural selection, gene flow, genetic drift, and mutation.
