What form of reproduction enables reshuffling of genes?
Asexual Reproduction
Which types of mutation can add genes to a chromosomes?
insertion and deletion
Which causes more variation within a population from generation to generation mutation or sexual recombination and Why?
Sexual recombination only takes genes already extant and make new combinations. Mutation presents a brand new variation ( if not neutral or deleterious ) to the eye of natural selection. So, mutation, from generation to generation.
If a gene is changed in a way that causes a new trait to appear?
A mutation is a change in genes or chromosomes that causes a new trait to be inherited. Mutations play a part in both normal and abnormal biological processes such as evolution, cancer, and the development of the immune system.
What are Stability Genes?
Stability genes are one of the three main genes, that when mutated are associated with cell progression towards tumorigenicity. It's normal function is to control the rate of mutation, but if mutated it off-balances, effecting oncogene and tumor suppressor function. In other words, accelerating the mutation process.
What form of reproduction enables reshuffling of genes?
Asexual Reproduction
What type of mutation causes autism?
The mutation that causes Autism is a rare genetic mutation. There are three different genes that are linked to the cause of different disorders on the Autism Spectrum.
What causes a four-leaf clover?
four-leaf clovers is caused by somatic mutation of genes
Which types of mutation can be add genes to a chromosome?
A deletion mutation can take genes away from a chromosome.
What are three categories of genes that when mutated can lead to tumor formation?
· 1) Genes involved in cell division · 2) Oncogenes o Dominant-acting stimulatory genes o Normally low levels or expression is turned off o Mutation causes increased/hyper expression · 3) Tumour suppressor genes o Recessive-acting genes o Normally expressed to inhibit cell division o Mutation causes defects in product or no expression
Is the source of brand new genes in a population called mutation?
Yes, brand new genes can only come from mutation.
Sometimes genes are damaged or are copied incorrectly resulting in faulty?
A mutation.
Which types of mutation affects more genes a gene mutation or a chromosomal?
a gene is passed on from generations and a chromosome is just found in certain cells
How does different genes happen?
New genes appear in individuals by random mutation.
What is a non polar mutation?
a mutation in a gene that does not affect the downstream genes in an operon. ie. a polar mutation is one that DOES affect the transcription or translation of genes in the same operon downstream of your gene of interest.
How is cockayne syndrome caused?
Cockayne syndrome is a autosomal disorder caused by a mutation in two genes. It causes short stature and sometimes aversion to sunlight.
Why are the white tigers white?
It is a mutation of genetic genes.
