I think it’s Rhizobium I’m not sure though
A
A haploid cell formed in the male seminiferous tubules
The reproductive tissues of male and female humans develop similarly in utero until a low level of the hormone testosterone is released from male gonads. Testosterone causes the undeveloped tissues to differentiate into male sexual organs. Primitive gonads become testes; other tissues produce a penis and scrotum in males.
C is what i think is correct.
Genotype is 1:2:1 (1 Homozygous tall, 2 heterozygous tall, 1 homozygous short)
Phenotype ratio is 3:1
The heterozygous Tt and recessive tt could produce short pea plants if they were crossed.
Explanation:
Genotype is the alleles present for a particular gene. In the Punnett square we can see there will be three tall pea plants and one short pea plant but they can be either homozygous or heterozygous.
While phenotype is the exhibited trait by particular allele that is 3 tall pea plants and one small pea plant.
If Tt and tt are crossed 50 per cent chances of short pea plant is there.
