Sentences with phrase «resulting gametes»

Activity includes: • original cells in Prometaphase I showing bivalents and chiasma • cells in Prophase I showing chromosome line up during independent assortment • resulting gametes • (includes also - for an easier activity - cells in Interphase II showing cells after first round of division) Students to find matching cards (Prometaphase I, Prophase I and 4 resulting gametes) Aim: to get a greater appreciation of the variety in gametes created through crossing over and independent assortment during meiosis Print, laminate, chop up all cards, mix them up, go!

In this scenario, if a locus i contains a drive element and the next locus does not, then the drive cuts both wild - type alleles at that locus until both copies are disrupted, rendering resulting gametes nonviable (ci = 1).

Not exact matches

As part of these ongoing research activities, the DNA of Dravet patients without SCN1A mutations was analyzed by trio exome sequencing, which searches across the active parts of the genome for de novo mutations that have arisen in these patients (de novo mutations are DNA copying errors that occur in the parents» gametes or in the fertilized egg or embryo, resulting in the afflicted family member being the first person in their family to have this genetic condition).

During meiosis, the genome of a diploid germ cell, which is composed of long segments of DNA packaged into chromosomes, undergoes DNA replication followed by two rounds of division, resulting in haploid cells called gametes.

Recombination ensures that each gamete ends up with a unique copy of every chromosome, but when the process goes awry, it can result in chromosomal abnormalities.

Most of the few studies on children born as a result of gamete donation show them to be well adjusted psychologically.

The causes of infertility, which affects around 10 % of couples, are often unknown, but may in some cases result from the body's inability to produce viable gametes — also known as sperm and egg cells.

In meiosis, which is required in sexual reproduction, one diploid cell (having two instances of each chromosome, one from each parent) undergoes recombination of each pair of parental chromosomes, and then two stages of cell division, resulting in four haploid cells (gametes).

This was attributed to «recombination» taking place between the marker and the actual gene during the formation of gametes (sperm and eggs), resulting in the marker normally associated with the mutant gene and that associated with the normal gene being «switched over».
