What is the probability that the propositus is a heterozygote. In a normal human

Question

What is the probability that the propositus is a heterozygote. In a normal human cell, how many telomeres would be present in each nucleus during meiotic telophase 1? Below are a wildtype and mutant DNA sequence. Identify the type of mutation observed. When would the synaptonemal complex break down? During which phase of meiosis docs synapse begin? A testcross yields offspring in the ratio of 50% heterozygous and 50% homozygous recessive. What are the genotypes of the individuals in the cross? What is the order of condensation or packaging of a chromosome as it progresses through mitotic Prophase? Identify- the most likely mode of inheritance for the following pedigree. Identify- the most likely mode of inheritance for the following pedigree of rate trait.

Explanation / Answer

Answer 7 - Option c - 0

Propositus is a member of a family which is usually exceptional in phenotype. Generally the phenotype of Propositus might be dwarf. Thus the probability of propositus being a heterozygous is zero. The dwarf or recessive characters expressed themselves only under homozygous conditions.

Answer 11 – option b – Zygotene

Synapse begins during zygotene phase of meiosis.
