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
Eukaryotic cells are larger than prokaryotic cells and have a “true” nucleus, membrane-bound organelles, and rod-shaped chromosomes. The nucleus houses the cell's DNA and directs the synthesis of proteins and ribosomes.
So..the answer should be D. Eukaryotic cells have a true membrane-bound nucleus and prokaryotes do not
All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. Prokaryotic cells lack a nucleus and membrane-bound structures. Eukaryotic cells have a nucleus and membrane-bound structures called organelles.
So..it can't be C. or A. or even B.
