Justify your answer by filling in the blanks. Both parents have white fur. way that this can happen is if their genotypes are bo
MissTica

Answer:

Both parents have white fur. <em>The only</em> way that this can happen is if their genotypes are both <em>homozygous (bb)</em>. Therefore, both parents pass the (b) allele to every offspring. When you combine two of these alleles, the resulting genotype is <em>(bb);</em> therefore, the resulting  offspring have white fur.

Explanation:

A homozygous trait can be described as a trait in which both the alleles for a gene are similar. A heterozygous trait can be described as a trait in which both the alleles of a gene are different. If an allele masks the effect of another allele, it is said to be dominant. the allele that gets suppressed is termed as recessive.

Hence, for a recessive trait to occur both the alleles of a gene should be homozygous recessive.

The punnet square for the above cross is shown below:

        b       b

b       bb     bb

b       bb      bb

PLEASE ANSWER ASAP I AM BEING TIMED!!!
gayaneshka [121]

Answer:

Apart from poisoning the fish, this toxic fishing activity kills animals that are essential to the aquatic environment, such as corals, and provide food and shelter for a number of marine species. One square meter of coral reef is lost with every fish captured using this method. Also, overfishing has the potential to deplete main reef habitats and damage coral habitat. In many places, rapid human population growth, increased demand, the use of more advanced fishery technology, and insufficient maintenance and regulation have resulted in the extinction of key coral species and habitat damage.
