What form of genetic drift occurs from

belka [17]

Answer:

The correct answer is - B. disruptive selection.

Explanation:

Adaptive radiation is a type of genetic drift that relatively fast evolution of many species from a single common ancestor which means there is a big drift in a very small time.

Disruptive selection is a type of natural selection that shows phenotypes (individuals with groups of traits) of both extremes but has very few individuals in the middle. An example of this type is the evolution of mammals after the extinction of dinnosaurs.

Two phenotypically normal parents have a child with CF. i. What are the genotypes of each parent? ii. What is the probability th

katen-ka-za [31]

To first dive into your question, here are some vocabulary terms that I will be using and will be helpful to you as well.

Homozygous dominant (BB): Is not affected by cystic fibrosis.
Homozygous recessive (bb): Is affected by cystic fibrosis.
Heterozygous (Bb): A carrier for cystic fibrosis.
Phenotype (Ex: Having cystic fibrosis): The appearance of an allele pair.
Genotype (Ex: bb): The genetic makeup of an allele pair.

We know that if both of the parents are phenotypically normal, there is no way that they can be homozygous recessive (bb), or have cystic fibrosis. We also know that since they have a child with this disease, they can't be homozygous dominant (BB) either. This means that both parents have to be carriers (Bb) in order for them to have a child with cystic fibrosis.

Below I have attached a Punnett square with both of the heterozygous parents.

Each child they have will have a 1/4 or 25% chance of having cystic fibrosis.

4. A plant can have yellow (Y) or green (y) leaves. It can also have smooth (S) or rough (s) seeds.?

navik [9.2K]

A.) The phenotype is yellow, smooth

This is because (Y) yellow is dominant over (y) green. If an organism has a trait that is dominant, it will show up with no exceptions (YY, Yy, Ss, SS). Recessive traits on the other hand will only show up if both the maternal (Mom) and the paternal (Dad) copy given are both recessive (yy or ss).

b.) It depends on what the YySs plant is paired with. Will it be paired with another YySs, with YYSS, yyss, YySS, yySS, YYss...? For example, if it is paired with another YySs, make a punnett square.
