The genotype of the short-haired parents that produced some long hair offsprings is probably heterozygous.
<h3>What is heterozygosity?</h3>
Heterozygous means an organism which has two different alleles of a given gene.
An organism that is heterozygous posseses two different alleles of the same gene. For example, in this gene coding for hair length;
- L represents short hair (dominant)
- l represents long hair (recessive)
Therefore, if two short-haired parents produce 100 offsprings and 25 of them are long-haired, it means that they were probably heterozygous for the short hair.

Answer:
Explanation:
Crop rotation
Rotation of crop is important to help conserve nutrients that are available in the soil and prevent total use up of the nutrients. The same type of plants all year round on the same soil keeps on draining the land of the same nutrients needed for their growth. Rotation of different can help maintain soil nutrients level as some crop fixes nutrients in the soil.
Natural mulching
The use of cover cops as mulch helps protect the soil and allows for retention of nutrients. When cover crops are harvested the leaves can be turned back into soil to release nutrients that are stored up in the plant part.
Composting is the process of decomposing organic matter this could include animal waste such as dung,leaves both green and dead, kitchen. This waste are stored up, little water is added to moist and then allow to decompose it can be mixed together after few days to aerate after. After decomposing to form compost it can be added to the soil. It is usually rich in nutrients.
Answer:
The most closely related are amphibians and reptiles.
The least related are amphibians and mammals
Explanation:
Amphibians broke off from reptiles, birds, and mammals around 260 millions years ago and next up are the reptiles which broke off around 225 million years ago. So they are the most closely related
Mammals are the last to break off, around 200 million years ago. So they are the least related to amphibians.
