Question

A scientist observes a pair of separate chromosomes that have genes for the same trait arranged in the same order. However, some of the alleles for the genes are different. What is the scientist most likely observing?
A. homologous chromosomes with heterozygous alleles
B. homologous chromosomes with homozygous alleles
C. heterozygous chromosomes with heterozygous alleles
D. heterozygous chromosomes with homozygous alleles

Answer 1

Arranged in the same order, seen in homologous. 'homo' the same. however alleles for the genes are different so a heterozygous alleles. ''hetero'' meaning different and most likely seen a recessive gene that's why alleles are different.

Answer 2

so A
