Explanation: The buck is homozygous dominant, meaning he has two of the brown (B) allele. The doe is white, and since the allele for a white coat is recessive, it has to have two white (b) alleles.

Set up a Punnett square with BB on one side and bb on the other. The results of this are 4 offspring all with the genotype Bb. Because brown (B) is dominant, all of them are brown.

To find the chance of getting a brown deer, take the number of brown deer (4) and divide it by the total number of outcomes (4). This gets you 4/4 or 1. As a percent, that would equal 100%.

Answer fast please <br><br> How are tundra biomes good/bad for the environment?

Answer:

Threats to the tundra biome

The oil, gas, and mining industries can disrupt fragile tundra habitats. Drilling wells can thaw permafrost, while heavy vehicles and pipeline construction can damage soil and prevent vegetation from returning. This activity also increases the risk of toxic spills.

What is the environment like in the tundra?

Tundra ecosystems are treeless regions found in the Arctic and on the tops of mountains, where the climate is cold and windy, and rainfall is scant. Tundra lands are covered with snow for much of the year, but summer brings bursts of wildflowers.

What will happen to the frequency of the recessive allele for the hbs gene when there is an outbreak of malaria? the frequency w

Ad libitum [116K]

In the outbreak of malaria, the frequency of the recessive allele for the HbS gene will increase. The correct option is A.

HbS is a beta-globin gene known as sickle hemoglobin.

It causes sickle cell disease in humans.

The disease is expressed by two HbS variants or one HbS variant or one another beta-globin gene.

Malaria is caused by the plasmodium parasite, which is present in the saliva of the mosquito.
