Answer:

Dog breeding

Explanation:

Humans select traits they desire in pets,

Some of these traits would be selected against by nature:

Ex: Toy breeds have fragile bones, poor health and few defensive capabilities, meaning they are a snack to any predator even small ones like a fox.

Nature wants healthy, strong individuals, in the wild big enough to hunt and strong enough to fight off other predators.

In rats, the allele for long whiskers is dominant to the allele for short whiskers. At another gene locus, a dominant allele pro
PilotLPTM [1.2K]

Answer:

25%

Explanation:

We have 2 independent genes with 2 alleles each: L/l and W/w

  • W_: whiskers
  • ww: no whiskers
  • L_: long whiskers
  • ll: short wiskers

Individuals with short whiskers will have the genotype <em>WWll </em>or <em>Wwll</em>.

<u>A cross between a rat heterozygous for both genes and a homozygous recessive rat is done:</u>

<h3>WwLl x wwll</h3>

-The homozygous rat will produce only <em>wl </em>gametes.

-The heterozygous rat will produce the following gametes: <em>WL</em>, <em>Wl</em>, <em>wL</em>, <em>wl</em>.

If you do a Punnett Square, you'll get that 25% of the offspring will be WwLl and will have short whiskers.

Hemophilia is a disease that causes uncontrollable bleeding. If a father has it, all of his daughters will be carriers of the di
Ipatiy [6.2K]

Answer:

<em>Yes, the following description is true.</em>

Explanation:

Hemophilia is a sex-linked recessive disorder. This means that only one allele recessive allele for the trait in males will cause the disease to occur in males. However, for females, there should be two recessive alleles present for the gene for the trait to occur. A female carrying one recessive allele for the trait will be a carrier.

If a father is hemophiliac, this will mean that all the daughters will be carriers for the disease as they will have one of the allele for the trait from the father. On the other hand, about half of the sons will have the disease if they get the recessive allele from the father for the trait.
