The careful use of resources is called CONSERVATION. You can remember this because we are CONSERVING resources, which means to only use them when necessary.

Answer:
The parent with the genotype Aa BB Cc dd can produce 4 different types of gametes.
Explanation:
<em>The law of independent assortment states that the alleles for a trait separate when gametes are formed. </em>
In the parent genotype Aa BB Cc dd, the allelic pairs with variation present are Aa and Cc. Therefore, the source of variation in the possible combinations during meiosis, largely arises from these 2 allelic pairs.
Independently assorting these pairs, we have ; A, a, B, B, C, c, d, d
The possible combinations therefore are:
Answer:
The result will be two gametes with a normal haploid number (n), one gamete containing an extra chromosome (n + 1) and one gamete missing one chromosome (n − 1).
Explanation:
Nondisjunction is caused by the failure in the mechanism of separation of homologous chromosomes or sister chromatids during meiosis and/or mitosis. The failure in the separation of sister chromatids during meiosis II is referred to as 'secondary nondisjunction' and it produces two daughter cells with abnormal chromosome numbers.
The fusion of one gamete containing an extra chromosome (n + 1) with a normal (n) gamete will lead to trisomy (2n + 1), while the fusion of one gamete missing one chromosome (n - 1) with a normal gamete will lead to monosomy (2n-1).
