Answer:
The result when heterozygous male and homozygous recessive female crosses is Mf, Mf, mf and mf
Explanation:
let Mm represent heterozygous male
let ff represent homozygous female
i.e Mm X ff= Mf, Mf, mf and mf
this implies that their would be two dominant heterozygous male and two recessive heterozygous female
<h2>Answer:</h2>
When the crossing over results in both mutant alleles on one chromosome and the other chromosome will be mutation free.
<h3>Explanation:</h3>
During the meiosis chromosomes are present in homologous form in a pair.
They exchange their genetic material with each other. This exchange is random and usually genetic material on the ends/telomere changes with the homologous chromosome.
In given condition the exchange is in such manner that the mutant allel of one chromosome shifts to other during crossing over. While other chromosome also contains its own mutant allele and does not exchange it during crossing over.
Se denomina “energías renovables” a aquellas fuentes energéticas basadas en la utilización del sol, el viento, el agua o la biomasa vegetal o animal -entre otras-. Se caracterizan por no utilizar combustibles fósiles –como sucede con las energías convencionales-, sino recursos capaces de renovarse ilimitadamente.
