The following responses are true;
a. A cross between this cat and another curly ear cat will result in 100% curly ears
c. The genotype of the cat in the picture is $$
g. The genotype of the cat in the picture is S$
h. A cross between this cat and a homozygous normal ear cat will result in 100% normal ears
Explanation:
Because the allele for curly ears is recessive, then all the cats with curly ears have a homozygous recessive genotype ($$) because the don't have a domiant allele (S) to mask the effect of the recessive allele.
A cross between two curly-eared cats (which means they both are homozygous recessive individuals) will result in 100% curly-eared offspring with homozygous recessive genotypes.
A cross with homozygous dominant individual will result in all offspring being straight-eared but with heterozygous genotypes.
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:
Bacteria
Explanation:
Bacterial are prokarotes, that inhabit virtually all habitats..Although some may be pathogenic, ,most bacteria are beneficial. They live in mutual relationship with their living hosts.where they help most in catabolic reactions especially in digestion of food and in nutrient cycle.
They lack membrane bound organelles,they have cell wall made up of peptidoglycan, their nucleus is not bounded with double membrane like Eukaryotes.They vary in shapes, most are spherical in shape, with the shape determined by the cell wall and the cytoskeleton in the cystosol.
