1)Ganarles contain one kind of each chromosome because the homologous chromosomes separate during meiosis. True or False? 2)In humans, there are two alleles possible at the chromosome locus that determine blood type. True or False? 3) Mendel was a famous naturalist who developed the concept that lead to the laws of evolution. True or False? 4) Embryonic stem cells come from embryos made for research. True or False? 5) An organisms environment history, in addition to the phenotype, can influence the genotype. True or false? 6) During métodos homólogos chromosome sorteaste and the daughter cells have one copy of each kind of chromosome. True or False? 7) the surtidor include all the pair of chromosome except the X and Y Chromosome. True or False? 8) during DNA replication, the patent DNA molecule unerring and unzips. Then reach old stand serves as a template for a new stand. True or False? 9) mutations due to replication errors and environmental factors are quite common due to the proof reading function of DNA repair enzymes in cells. True or False? 10)dominant and recessives alleles have the same pattern of inheritance. True or False?

Expert Solution

Step 1

Homologous chromosomes are the chromosomes having two pieces of DNA in a diploid organism which have the same genes, one inherited from each parent. Both parents provide the complete genome. Furthermore, these chromosomes are homologs having set of one maternal and one paternal chromosomes and they pair up together inside the cell during fertilization.

Step 2

ANSWER

1. TRUE

The homologous chromosomes separate at the stage of Anaphase 1. At this stage each cell gets only one set of chromosome which results in the formation of haploid cell having one type of chromosome. Hence, the statement is true.

Step 3

2. TRUE

Each individual has two ABO blood type alleles which are I^A for A, I^B for B and i for O. There are two alleles at the chromosome locus that determine the blood type because each inherit one blood type allele from father and other blood type allele from mother.
