What are two types of genetic drift?
Founder effect- isolation of few individuals from larger population; new population forms with different gene pool. Bottleneck effect- Drastic reduction of population size leading to a restrictive gene pool in wich the population must use to recover. Forms population with different gene pool.
What does being heterozygous for some genetic trait mean?
the 2 alleles of the gene for the trait are different on the 2 homologous chromosomesBeing heterozygous for a trait means that they have different alleles for a trait. For instance: Tt would be heterozygous and TT or tt would be homozygous because they are both eitehr little or big t's.it mean the gene is not pure or for example suppose a person is blood group A but actually he is having A and O; because O is recessive trait the gene express the A trait instead, making the person having blood group A.
What are dominant and recessive genes?
A dominant gene- A gene That is "stronger" than a recessive geneA recessive gene- A gene that must have 2 of the same to have that look.ex: A gene for being tall=T (CAPITAL T)A gene for being short=t(lowercase t)TT=TallTt=talltt=shortThe GENES WHICH ARE EXPRESSED IN THE PROGENY ARE CALLED DOMINANT AND WHICH DO NOT EXPRESS ARE CALLED RECESSIVE
What gene is masked if it is paired with a dominant gene?
The different forms of a gene are called alleles. In Mendelian genetics, a gene has a dominant allele and a recessive allele. The dominant allele masks the recessive allele if present. So there are two possible dominant genotypes: homozygous dominant, in which both dominant alleles are present; and heterozygous, in which one allele is dominant and the other allele is recessive. The only way to express a recessive trait is to have the homozygous recessive genotype.
