When a dominant gene is paired with a recessive gene, the characteristic associated with the dominant gene will be expressed.

Explanation:

Recessive gene is not expressed when paired with a dominant gene as the alleles of the dominant trait will mask the recessive gene expression. The trait appearing in the offspring will be the dominant type. In other words, the dominant allele would dictate the protein to get appeared in the offspring.

What are the ways in which captive breeding helps protect biodiversity? Check all that apply
IgorLugansk [536]

Answer:

Following are the ways captive breeding helps conserve biodiversity:

  1. Captive breeding can increase population numbers
  2. Captive breeding can help remove species from the Endangered Species List
  3. Captive breeding can result in the eventual release of offspring into the wild.

Explanation:

Captive Breeding:

Captive breeding is an ex-situ conservation technique (taking the animal out of its natural habitat to increase population numbers in zoos or sanctuaries). Captive breeding involves selective breeding of endangered species to help produce a sizable population that can later be introduced back into the wild when their habitat improves.

Captive breeding programs include zoos, sanctuaries located away from the animal's original habitat. For example, the Toronto Zoo has operated a captive breeding program for the Blanding's turtle since 2012. The turtles are kept their for 2 years after birth and then released back into the wild.

In a hypothetical population of plants, flower color is determined by a single gene with two alleles. In a population of 500 pla
blondinia [14]

Answer:

In the F1 generation

RR = 0%

Rr = 50% (or 0.5)

rr = 50% (or 0.5)

Explanation:

A pink flowering plant has the genotype Rr. It is heterozygous for the allele. The alleles for this gene appears to show incomplete dominance, as the heterozygous phenotype is a blend of the two homozygous genotypes.

A white flowering plant has the genotype rr. It is homozyogous for the white allele

A punnet square of the cross is shown.

The resulting punnet square shows that only Rr and rr genotypes are possible, at a ratio of 50:50 (or 1:1). Therefore, the genotype frequency of Rr is 50%, and rr is 50% in the F1 generation. This can also be written as 0.5. It is not possible to get a red plant, as the genotype RR can not come from this cross
