Which of the below statements is correct? choose the correct answer from the following choices, and then select the submit answer button. answer choices if a diploid organism has identical alleles at different loci, it is considered
a. a homozygote an organism with one gene per trait is considered
b. a homozygote a heterozygote diploid organism has a different genotype and phenotype
c. an organism with two different genotypes is considered a homozygote
d. a diploid organism is heterozygous for a trait if it has two different alleles

The correct answer is option D.

Explanation:

In diploid organism, chromosomes are present in pair. One chromosome is inherited from mother and one from father. The chromosomes pair is termed as homologous chromosomes. They are similar in shape, size, number of genes present, sequence of the genes, position of centromere, et cetere.

Thus, option A is incorrect.

However, the genes may have different allele. For example chromosome 1 (maternal) contains one dominant allele, say T, while chromosome 1 (paternal) contains recessive allele at the same locus, say t,.

So, if an organism contains same alleles for the trait then, it is termed as homozygous for that trait. It can either be homozygous dominant (TT) or homozygous recessive (tt).

Thus, option B and C are incorrect.

However, of an organism contains two different alleles for the trait then it is termed as heterozygous for that trait (Tt). The phenotype is usually resulted from the expression of dominant allele.

Hence, option D is the correct answer.

because they want 2 and yea

1. what is the relationship between the shape of an enzyme and the reactions they catalyze?

2. how does an enzyme inhibitor work?

separate your answers so i dont get confused : )
