The cramps can be caused due to anaerobic respiration in the muscles and lactic acid formation.

During intense physical activity the muscles become deprived of oxygen, in this condition, anaerobic respiration takes place in the muscle cells causes the formation of the lactic acid.

The physical training increases the strength of the muscles, which can help the muscles not to get tired easily. that is why, physical training is required before any marathon.

The most likely cause of cramps in Bradley's thighs would be the build up of lactic acid. This is a side effect of longer and strenuous activity during which you continouosly tax your body - or rather your muscles where they would need a lot of energy to properly function.

Can plants be heterozygous?
svet-max [94.6K]

The plants ploidy is decided based on the chromosome within the nucleus . Plant can be either heterozygous or homozygous.

The major distinction between homozygous and heterozygous individuals is that the former have two identical alleles while the latter have both dominant and recessive alleles. Over several generations, kids with the same characteristic are produced through self-breeding between homozygous individuals.

Heterozygous and homozygous chromosomes are seen in human beings. Allele pairings are categorized as Heterozygous and Homozygous. A heterozygous person possesses various alleles, whereas a homozygous person carries a pair of identical (RR or rr) alleles (Rr).

Let's take the gene for hair colour as an example. This gene has two alleles, one of which is responsible for black (r), and the other for black (R). On a homologous set of chromosomes, such as RR or rr, homozygous people will carry the same colour allele, but heterozygous people will carry distinct colour alleles.

Hence, depending on type allele can be homozygous or heterozygous.
