Telomere (ends) Centromere (middle) 2A 2B Chimpanzee Chromosomes Human Chromosome 2 What does the diagram tell us about the evolutionary history of humans and chimpanzees? Select all true statements. O Humans and chimpanzees have a different number of chromosomes and are therefore unrelated. Human chromosome number 2 is a fusion of chimpanzee chromosome 2A and 2B. Human and chimpanzees share a common ancestor.

Why do some genes express themselves later in life? Why not earlier? How many chromosomes in a human that has trisomy-15? How many chromosomes in a human that is triploid?

Homologous chromosomes are Group of answer choices inherited from 2 parents are sister chromatids are different in size and length different genes

A human protein, MC1R is responsible for telling human cells what type of pigment proteins to produce. One version of MC1R causes cells to make red pigments, while another version causes our cells to make black pigments. The red version causes red hair. The black version causes black hair. The two versions are called O homozygous and heterozygous homologous chromosomes alleles sister chromatids
