Correct question:

if a nondisjunction occurs at anaphase I of the first meiotic division, what will the proportion of abnormal gametes (for the chromosomes involved in the nondisjunction)?

Answer:

100%

Explanation:

Nondisjunction at meiosis-I means that two homologous chromosomes of at least one homologous pair fail to separate from each other during anaphase-I. This would result in the formation of one cell with one extra chromosome and the other with one less chromosome by the end of meiosis-I. Meiosis-II in these two cells would maintain this chromosome number in the daughter cells. Therefore, out of the total four gametes formed by the end of the meiosis, two would have one extra chromosome and would be denoted as "n+1". The rest of the two gametes would have one less chromosome and would be denoted as "n-1".

garik1379 [7]

A man with hemophilia (a sex-linked recessive condition) has a daughter without hemophilia, the probability of their children having hemophilia is 50%, out of 4 children probably 2 will have hemophilia and 2 will not have hemophilia.

<h3>What is recessive and dominant?</h3>

The dominant term is related to the genetic transmission of a trait and is represented, in biology, by a capital letter (A, B or V). While recessive, represented by a lowercase letter (a, b or v), they represent genetic traits transmitted only in the absence of the dominant gene.

With this information, we can conclude that Recessive genes produce proteins considered “defective” as they become inactive. That is, they are hidden (recessive) with the presence of a dominant gene manifesting their characteristics in the absence of their dominant allele.
