The question is incomplete as it does not have the options which are:

aneuploids

allopolyploids

amphipolyploids

autopolyploids

Answer:

Autopolyploids

Explanation:

Autopolyploid refers to the ploidy condition in organisms in which the ploidy level of organism increases that is multiple set of a single chromosome is formed in tissues.

The autopolyploids condition is observed more frequently in the plants than the animals when the tissue cells divide.  In the given question, the chromosome number increases or double that is from 18 to 36 to 54, 72 and 90. This shows that the ploidy level is increasing.

Thus, Autopolyploids is correct.

Brown hair is dominant over red hair. What will the genotypes and phenotypes of the offspring of a cross between a homozygous br
beks73 [17]

Answer:

1) The alleles for homozygous brown hair will be BB.

2) The alleles for heterozygous brown hair will be Bb

3) Let's make a punnet square to check for the outcomes:

       B          b

B   BB        Bb

B    BB       Bb

4) The results from the punnet square depict that the phenotype of all the children produced will be brown hair.

5) The punnet square depicts that there will be a 50% probability of the child to carry the heterozygous genome (Bb) and there is also 50% probability for the child to carry homozygous dominant genome (BB).

Rabbits.

Explanation:

The different organism and non native species are known to reach the plague proportions. They are responsible for the disease formation in their as well as in other species as well.

Rabbits are one of the species that has reached the plague proportion. They were brought under the control after the disease has been introduced that affected the rabbits species only.

Thus, the answer is rabbit.

Alja [10]

The correct answer is: A) metabolic enzymes require vitamin cofactors, and affected individuals have significant nutritional deficiencies.

Garrod exanimated urine chemistry because he believed that it is reflection of systemic metabolism and disease. He wanted to understand disorders of metabolism such as alkaptonuria. By studying urine of mother that has disease and later her child’s urine he made a conclusion that it is inherited (Mendelian pattern of inheritance).
