Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells.
The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.
Heterozygous Red- Rr
Homozygous Red-- RR
Homozygous white-- rr
Monohybrid cross- Rr
Recessive allele- homozygous white i.e rr
Explanation:
Heterozygous have 2 different alleles of a gene as both Red and white alleles are present in the example Rr.
Homozygous: If the 2 alleles at a locus is same then they are homozygous, it can be dominant as RR or recessive as rr.
Recessive gene are the ones that can be masked by the dominant genes as red is dominant on white.
Monohybrid cross is the result of cross between the individual having either homologous dominant or recessive genes or genotype. The result is generally masking the recessive allele resulting in dominant phenotypic trait but the genotype changes.
From the example given in question:
A cross between dominant red as RR
and a cross between recessive white as rr
The punnet square shows:
r r
R Rr Rr
R Rr Rr
it can be seen that all progeny are red but genotype changed to heterozygous red as Rr
Answer:
"You need to take a swab from the zone of inhibition and use it to inoculate a new plate without the antibiotic. If the organism grows then it was simply held in a static state by the antibiotic."
